Does your car need new transmission fluid? If so, you’re about to find yourself in the great transmission flush vs. change debate. What’s the difference between these two services, and which one does your car need? We want to give Annapolis, Highland Beach, and Hillsmere Shores shoppers the answers.
Read ahead as we take you through the different services. If you have any questions or want to schedule transmission fluid service, reach out to us at BMW of Annapolis!

When you have a transmission fluid change, the pan is drained and the filter is replaced. Not all your old transmission fluid will be removed during a change, however. Up to half of it might remain in the torque converter or cooler lines. It’s an effective way to replace some of your old fluid.
Mechanics will often drain and replace the fluid many times to dilute the old fluid and maximize the new fluid levels. Your new fluid, even if not 100% new, will still be more effective than the old fluid.
How often should you have your transmission fluid changed? The interval differs for every car, so check your maintenance schedule to know for sure. Most drivers won’t need a fluid change more than once every 30,000 miles or two years—whichever comes first.
Transmission flushes are often considered a more effective way to drain your fluid. When the system is flushed, all your old fluid will be emptied via a cooler line flush machine or a pump inlet flush machine. This optimizes your transmission’s performance since it runs on 100% new and clean fluid.
Since this service effectively acts as a replacement for a fluid change, you can have your fluid flushed at the same interval as you would have your fluid changed. If you choose to flush your fluid, you may be able to extend your fluid service interval.

Transmission fluid is used to lubricate moving parts in your transmission. It reduces wear and tear to the transmission caused by friction and helps keep the system from overheating. If you want to avoid costly transmission repair, replacing the fluid every so often is essential.
Fresh transmission fluid is usually a bright pink or reddish color. As your transmission fluid ages, it turns brown and then black. You can physically check the condition and color of your fluid to know when it’s time for a change.
Annapolis, Highland Beach, and Hillsmere Shores drivers can boost their cars’ performance with either a transmission flush or a fluid change. A transmission flush is more thorough and can possibly extend the life of your new transmission fluid.
Feel free to reach out to the service technicians at BMW of Annapolis for a consultation on your vehicle. We’ll be happy to help you determine whether a flush or fluid change makes sense in your case. Contact us to schedule transmission service today!
BMW of Annapolis, Old Mill Bottom Road, Annapolis, MD, USA
This is by far the best BMW dealership in the country. The people are all great and amazingly helpful. Sean Peria is exceptional and always very knowledgeable. If you are considering a new automobile purchase, visit these people. They will not disappoint.
Ester was an amazing experience. She was really transparent and really helpful in the decision of what cars were better for us. We really enjoyed working with her.
The team at BMW Annapolis is awesome! Lead by GM Dan Bailey, my sales contact, Esther Adekoya, & finance manager, Reina Boucher. My family & I had a great experience!
We bought a brand new BMW and we were in and out of there in no time. Our Salesperson, Kai Davis made every effort to ensure I got exactly what I wanted. He made the whole process smooth and easy. Best car buying experience ever!
Third time visiting service department had good services. No complaints was able to schedule appointment within 30 mins of needing one.
BMW Annapolis is the only dealer I go to for maintenance. Their staff and service is outstanding. My guy is Justin Phipps, he always explains everything and is patient on every visit. Calls to give updates and gives you his honest opinion about your repairs.
Andrew Coughlin has the best service mentality ever! He truly cares and goes the extra mile to give you an A++ experience
I had an amazing experience at the dealership from start to finish. Nat was outstanding…knowledgeable, patient, honest, and never made me feel pressured. He made the entire process smooth and stress-free and went above and beyond to make sure I got the right vehicle. I highly recommend asking for Nat if you’re looking for a great car-buying experience\!
Amazing helpfull and efficient Ben knows his stuff and takes time to explain. THANK YOU
I decided to take my car to BMW of Annapolis for a repair because it is closer to my home than BMW of Silver Spring, which has been my service provider for years. Big mistake.
Unfortunately, my experience with BMW of Annapolis was extremely disappointing, particularly when it came to customer service and communication.
I was assigned a service advisor who was able to assist me during our initial conversation. However, he did not inform me that he would be going on vacation the following day for an entire week, nor was I referred to another advisor who could assist ... Read More

Easy scheduling, honest friendly service and really enjoyed the new modern comfortable waiting area with tv's, coffee and snacks. Knowledgeable staff. Will definitely continue to trust them with my car.
I always get excellent service at BMW of annapolis. The service team is always courteous and customer oriented knowledgeable and professional. This is my third x5, and I always bring my cars to BMW of annapolis because i'm assured that the technicians will maintain my car properly... No guesswork!
Top notch, the staff is super pleasant and easy to deal with answering all concerns and questions with courtesy. Great job!
I had an excellent experience in the service department. Nick and my service tech provided a detail explanation of the issue and was able to correct the issue without it costing me an arm and a leg. I appreciate their integrity and commitment to providing excellent service and next steps.
I've been researching for a nused vehicle for weeks, and after having not-so-good experiences at other dealerships, I finally landed at BMW of Annapolis. I had found the vehicle I (thought I) wanted, but it was at a partner dealership. Bing, the salesman, drove to pick it up, but they had sold it the day before without updating the inventory. Being the superhero he is, Bing scoured the lot and found something that was even better. It was a year newer, had about half the mileage, and was loaded to the brim with features. And the cherry on top? ... Read More

Much improved in promptness and efficiency.May not be the most econical place to get work done.
Always a pleasure to visit and be serviced… I’ve been a client since 2012 and I have never had a bad experience… keep doing what your service agents are doing!!!!
Outstanding experience. My second. Leased by my agent from a Virginia dealer. I had an early problem they wouldn’t support me with and since I also own a home in Annapolis I asked for their help. They welcomed me and my car, and solved the problem immediately. Brought the car back for routine service, same great experience. Another recent problem, so do I reach out to, BMW of Annapolis. Found me a cancellation so accommodated me very next morning with service and loaner car. Allow me to get back home and start seeing planned telemedicine patients during the schedule ... Read More

Noise from left front tire while traveling from Virginia to Annapolis got progressively worse . Upon unanticipated arrival at Annapolis BMW it was repaired immediately upon arrival. Outstanding service!
Was very satisfied with all the services I received from the time I walked in that establishment would recommend to family & friends for buying a car check out sales rep Chloe
Nice atmosphere, and the staff are great. Highly recommend! They cleaned the vehicle after it was serviced.
Very detailed checkups and explanations with honest advice. State of the art reception waiting areas for owners, fully stocked for your convenience. I have had the same advisor for 10 years!
Had a great experience at BMW of Annapolis on Friday, July 11th. My i4 had an unrepairable flat on the right rear tire that they installed for me back in May. Called the service department and they were able to fit me in the same day while ordering the tire for delivery in the afternoon. My service advisor, Justin, noted the flat tire had a road hazard warranty in effect that saved me the cost of the tire. During installation thy found my left front tire had a bubble and were able to replace that one as well during the ... Read More

I have been using BMW of Annapolis for the last 8 years for my regular X3 and for the last 3 years for my X3M. They really understand M cars. They perform only the maintenance that is necessary, without trying to upsell me services that I know I do not need. I did some cosmetic customization to my X3M and they did not say a thing (another dealership gave me a long spiel about voiding the car's warranty). Also, the recently renovated waiting area in the service building is super nice.
Service rep was very nice and helpful. We had a minor problem with my aftermarket wheels not being compatible with BMW alignment procedures. I was able to go home and swap them and the rep made certain that my car was taking care of. Great service!
My 2nd BMW. Purchased both at this dealer. Very nice to work with. I recommend this dealer
Donate was super helpful and the entire experience was great. Everyone was friendly, I was in and out in 90 minutes and appreciated the regular updates I was provided.
Thank you to BMW Of Annapolis helping me keep my 15-year vehicle in perfect running condition. My vehicle is at the age with extremely high mileage -where repairs are expected (regular service/maintenance helps keep to minimum). Recently had front brakes replaced - vehicle is back on the road and running smoothly. Quality vehicle and service team -I am keeping the vehicle despite buying new 2026 BMW. Shoutout to my Service Advisor Jane King and the entire service team. Thank you.
Effecient, professional service center. While my vehicle is serviced, I am kept abreast of status without prompting.
I had my oil light come on and was able to get an appointment the same day. The staff was amazing and very professional.
Paul is great and always takes care of me! He addressed all of my concerns and then some.
I've brought my vehicle here several times, and unfortunately the experience has been consistently disappointing.
From the moment I arrive, the service advisors often seem annoyed or unwelcoming. More than once, I've been left standing at the service desk for several minutes without being acknowledged or greeted.
Communication throughout the service process has also been lacking. During my most recent visit, I never received a call or update that my vehicle was ready and had to reach out twice myself to find out the service had been completed.
What concerns me most is that my vehicle often seems ... Read More

The new service facility is very nice (they just need more outlets to charge devices) and the checkout process was a bit confusing in terms of where to go to pay. Otherwise, everything else was great!
Best service department around! Robert Kozora was my service advisor and he was great to work with highly recommend!
I was told the oil change service would take 1.5 hours. It took 3.5 hours.
Easy drop off. Good communication with the service department. Vehicle was ready when requested. No other issues
Great dealership, Andrew helped us throughout the process and helped with setting up the vehicle.
I have serviced with them for 10 years. Great team… from front desk to technicians!
They identified problem. Presented the solution . Did the work at cost estimated. Done in timely fashion. Thank you!!
Oil change required a little over 2 hours. It included an inspection and wash but still required too much time. The waiting area was respectable. Not sure why it took as long as it did, I was not given an explanation.
The mechanic who worked on my X5 did not complete the job. I had 4 tires replaced and 1 rim. I now get a error message when I start the vehicle advising me to return the vehicle to the service department I contacted Andrew ( great sales person) who sold me the vehicle. He called me back with 10 minutes with corrected action Thank you Andrew
Devon Binns is an excellent sales manager. He understood my goals and was able to get a win win deal. My new car is beautiful.
Came in for an oil change with coupon. Service completed in under 2 hours. Recommended tire change for 4 wheels. Advisor informed me of how many more miles I could go before it became absolutely necessary. Clear and prompt communications without any pressure to service immediately.
I purchased my used 2018 430i Gran Coupe 3 mos ago and brought it in for an oil change. At which time I was told there were several things that needed my attention but nothing significant. I purchased the oil package and declined the additional repairs..
I went in yesterday for another oil change because I have been traveling slog and I was due. Ome of the first things I mentioned was my oil package at check-in. Fast forward I receive the service video at 9:17am, about an hour later I’m presented with a quote for items not even mentioned on ... Read More

The service advisor, Jane, was condescending and began recommending services before the vehicle had even been properly inspected. Unlike previous visits, no thorough check of the car was performed to determine its actual service needs. Instead, the recommendations appeared to be based solely on prior service history rather than the current condition of the vehicle.
Additionally, I did not receive the inspection video that is normally provided, which further reduced my confidence in the service experience. Overall, I was very disappointed with the level of professionalism and customer care I received from this advisor. Based on this experience, I would ... Read More

I made a quick visit to the sales area and the person who directed me to the service department was incredibly unwelcoming. We bought several cars from this dealership.
Just bought my 5th car from BMW and as always tge experience was outstanding. Andrew, Dan and David are the best. Thank you!’
Sevice was fast and on time, my advisor kept me up to date on what was going on and was done in the time they stated.
Quick and efficient. Love video from tech and the text messages keeping me updated. Of course the cost was high.
Great service operation. Drop off and pickup were smooth with attentive attendants. Nice facility also
Sean pereia is my service advisor. He was very attentive and helpful with my concerns. He updated me appropriately with the progress on my car.
Very prompt and professional service. Plus, my advsior, Jane, got me a last minute loaner.
Ayan was great to work with and great communication.Efficient experience , car was spotless when I test drove it. 10/10.
Professional members of the Services Team... Initial meeting transparent and open about approximate time the fix would take...after the mechanic reviewed my vehicle, he offered a video to show me what else was needed... this digital touch saved us both time and any possible misunderstanding... after my approval...I received a new approximate completion time... communication is the key here and much appreciated!
Excellent service and was able to get me taken care of quickly and with a great deal
My service person, Shawn, was amazing, professional and very helpful. I am grateful to him and would recommend him to anyone.
Great service and like the new renovation. Justin was very helpful. Thank you. I don’t like the mandatory word count on this.
Very dependable, they are concerned about the upkeep of your vehicle, they help you with the cost of your final bill. They also clean the exterior of your car before you get it returned back to you. They serviced both of my vehicles in 3 months.
Donte was my service advisor today. He was very nice and knowledgeable. He even went the extra mile for me. He was easy to access and communicate with. Which had been a problem in the past I give Donte five stars.
Very good to deal with. Up front on pricing. I have confidence in the work they do.
Shawn on the front deck representative is always amazing. Amazing amazing I enjoy working with him always pleasant.
Outstanding! Everyone is professional and caring takes the time to explain the problem. The dealership is beautiful and very clean Relaxing and comfortable waiting area
Communication from service department was very poor. Failed to call back to confirm tire was in stock so I could schedule an appointment, then failed to timely provide pricing for tires. This resulted in insufficient time for an oil change to be done as part of the requested services.
Always give a video of inspection and have your car ready when they say they will. Always willing to work with the customer.
I have to assume the service/repair was good. But I know the customer service was great because Jeremy Connie kept me informed throughout the process. Outreach to the customer is king!
Andy and David were very professional & they were very open & honest concerning my recent vehicle purchase. The customer service was outstanding!
Thank your Jeremy and Jeff for the quick service times and fitting me in the packed schedule. I will always service my BMWS Here!
My visit was very pleasant and my service advisor, Dontae was very friendly and attentive. I waited in the lounge area while my car was being serviced. The lounge is very comfortable and there are plenty of snacks and beverages available. An overall very positive experience.
Fantastic new facility! Sean is always amazing - efficient, friendly & very professional. Would highly recommend him & his team
Staff was nice, waiting area was clean. took 3 1/2 hours for an oil change.
Dealership was really nice and organized. I was able to make my appointment and drop off my car at my leisure and the turnaround time was quick.
Trusted source for all of your car needs. Speedy, professional, and knowledgeable staff. Book your appointment now!
Great service! I always appreciate the excellent customer service. Special thank you to Jeremy and Nicholas.
Service department is state of the art upgraded experience for customers waiting for their vehicles. Transport to work is also available at the dealership. Nick was professional, responsive and very attentive. Overall experience was five stars.
Totally pleased with my Service Advisor, Dontae for his professionalism and honesty related to the needs of my SUV serviced today, 4/18/26 and also to Charles for the inspection and expertise with acknowledgement of a needed service - not imminent but necessary. Honesty and Expertise is vital and so appreciated at BMW Annapolis demonstrated by these employees. Dealership's get a bad reputation for overcharging for unnecessary service but I have confidence this is not exhibited at Annapolis BMW with their visual inspection sent to Customers - thank you.
BMW of Annapolis service center, and especially Jane King, are phenomenal. Knowledgeable and customer friendly does not scratch the surface of just how superb this agency treats us each and every time we stop in for routine maintenance. We even had a refresher course with Daniel Anderson on just how much our BMW can do with its connectivity to our phones and with just asking Hey BMW…. I cannot finish writing a glowing review without mentioning Andrew Coughlin our sales person and contact who always has time for our questions. Overall this agency is an absolute pleasure.
I have received service at multiple BMW dealerships across North Carolina, New York, and Maryland, and Justin Phipps is by far the best service advisor I’ve encountered. He is professional, welcoming, and truly puts himself in the customer’s shoes—anticipating needs and addressing concerns promptly and thoughtfully. Thank you, Justin, for delivering such an exceptional service experience!
I’ve been trusting your service manager Jane King for over 20 years. She’s been my go to for exceptional customer care. I’ll recommend her/your dealership to any BMW owner!!!
They went above and beyond to get my flat tire fixed that I had to tow to them. It was completed in a day and even made time to add an oil change I had asked if they could do. The sevice manager Eric was great and went out of his way to talk to me and get my car back to me without any inconvenience to me. Thank you!
Jane King, Service Manager, explained in detail the work that was required . Very satisfied with service.
Very quick, friendly and polite. Great waiting area with coffee and WiFi. Always makes the wait for my car easy.
Great service! Justin and Dontae were very supportive of my plight with this car. See you in a couple of months for my next oil change.
We’ve bought three 540 IX drives from them. We are always satisfied with the service team.
Friendly employees and no pressure approach during test driving and purchase of the 2018 X3
I recently had an unforeseen situation occur with my vehicle the end of January. I unfortunately hit a pothole and I had to be towed to BMW of Annapolis since I have only had my vehicle serviced through them the last few years of ownership and trust their customer service. Jane King contacted me the following morning to introduce herself, as well as to let me know that my car had arrived safely the night before. With the pending snow storm rapidly approaching the area, Jane let me know that my vehicle was safe and that she would keep in ... Read More

Love the online shopping experience. The price was negotiated online with ease. The salesman, Andrew, was the most courteous and knowledgeable. He made our leasing transaction a very pleasant experience.
Great fast service. Honest analysis of issue. The only negative is there is no shuttle service. I had to take Uber to get home.
All the staff was professional courtesy and makes you feel so welcoming there. It’s alway a great Nick is the best he really time to explain in detail with you thanks
Great service. It's the only dealership that I go to service my car. I have only had good experiences.
Excellent service and environment! The new service bay renovation is absolutely beautiful. Such a welcoming environment, along with the welcome vibe from the service advisors and techs. I highly recommend BMW of Annapolis and will continue to use them for all my BMW needs.
All 4 wheels exhibited damage after new tires were replaced on 740 Ld! Not happy!
Nice workers, horrible wait time. Oil change and brake fluid took a little over 3 hours.
I purchased my car from BMW of Annapolis in 2017. I’ve had all of my maintenance done through the dealership. The customer service is always top notch and my last visit even went beyond that excellent service. I had quite a bit of planned maintenance scheduled. My service advisor, Sean Peria took the extra step to research the dealership current discounts and saved me over $500! BMW of Annapolis is awesome!!!
Great First Experience After recently relocating to Maryland, I had my first service visit at BMW of Annapolis and couldn’t be more pleased. I was able to get a quick appointment with a loaner car, my BMW iX xDrive45 charging issue was resolved promptly, and they completed my Maryland state inspection for registration during the same visit. My service advisor was professional, pleasant, and very helpful. The entire process was smooth and stress-free. I look forward to returning for future service.
Very professsional and pleasant experience.everyone was helpful and good communication. Let me know all steps of my serbice
Service was needed and resolved efficiently. Tpms tire issue. Kudos for the renovated service building. Beautifully executed. Seating is varied and comfy. The view is great, parking area full of shiny new cars. Tempting.
The service department is very nice to deal with including letting me know that my brakes and tires are close to needing replacement.
My truck now has engine issues after spending $5000 worth of work done and all the suggested work done I needed. They did a full diagnostic. 2 weeks later my trucks engine is overheating. I think they are purposely sabotaging vehicles.
Service department is excellent. Jeremy Miller always addresses my issues and concerns. Highly recommended. Would not take me vehicles to another dealer service department.
The Annapolis BMW dealership has taken care of my BMW since I’ve had it. They are always been polite and thorough in their service.
