When To Change Transmission Fluid
For most manual transmissions, you should change your fluid every 30,000 to 60,000 miles; for most automatic transmissions, you should change your fluid every 60,000 to 100,000 miles. Of course, these numbers can vary significantly from model to model, so we urge you to check two resources:
- Your Car’s Factory-Recommended Maintenance Schedule
- Our BMW of Stratham Team of Expert Auto Technicians
After all, we’re here to help all of our New Hampshire customers with their automotive issues: from Stratham to Portsmouth to Exeter and beyond. Contact BMW of Stratham today to set up your appointment!
What Is Transmission Fluid?
Transmission fluid is a slippery, low-viscosity liquid that lubricates the incomprehensible number of moving parts that make your transmission tick. From the torque converter or the clutch to the gears themselves and beyond, transmissions have a host of whirring parts that need to play nice together.
Automatic Transmissions. It should be no surprise that ATs use automatic transmission fluid.
Manual Transmissions.On the other hand, however, MTs can use a variety of substances, from traditional motor oil to heavyweight hypoid gear to automatic transmission fluid. It all depends.
What’s The Importance Of Changing It?
If you don’t change your transmission fluid, you’re going to have a variety of issues, depending on which type of equipment your vehicle is running (i.e. automatic or manual). Here’s a breakdown of the issues.
Automatic Transmissions. These produce a lot of heat, which can actually degrade and break down your fluid over time. Degraded automatic transmission fluid won’t lubricate all those parts properly, so you’d better schedule an appointment if you’re overdue on your maintenance schedule. Get in touch with us!
Manual Transmissions.While the fluid won’t degrade like above, it will become contaminated with bits of shaved-off metal from your manual transmission’s various parts: synchronizers, bearings, gears, etc. Contaminated oil doesn’t lubricate as well as clean oil, so reach out to us to schedule your appointment.
How To Check Your Transmission Fluid
Last, but certainly not least, we’ll share a few tips on how you can check your transmission fluid yourself.
Automatic Transmissions. This is a cakewalk – just pull out the dipstick and look for the consistency. Make sure that you do this while the engine is warmed up and the vehicle is safely in park.
Manual Transmissions.This is so difficult to check on your own that it’s almost in possible. In fact, for most makes and models, you need to have a car up on a lift in order to check it. So, call a mechanic!
Schedule Transmission Service
We’ll conclude by offering you an expert tip – your transmission fluid won’t burn up in the same way as your engine oil. So, if you check the dipstick and the levels are low, that means that it’s probably leaking. In that case (or in any other case), our guys and gals can help. Just schedule service online in a few clicks.

Our Reviews:
Friendly service, I didn't have to wait long. Quick and easy. Offered a loaner vehicle.
I moved from Illinois where I serviced my BMW’s for years. The customer service there was fabulous and I was a bit nervous going to a new place after 25 years. My worries were wasted as the client service by Cory was fabulous and the work on my car was phenomenal. I had new brakes, tires rotated and my car detailed and it is like new. Thoroughly impressed!!! My new favorite place!! Thank you!!!!
Pawel always goes out of his way to make things easy and get things right.

Andrew and salesman weee great. Finance manager should be fired for his high pressure outright lies. Terrible time cancelling unwanted extras for his commission. Still trying to cancel one
Everyone always very kind, helpful and knowledgable. Great communication. Dealership is always clean. They are usually on time with car being taken in and ready.
Had a great experience at BMW of Stratham. They completed multiple service requests while I waited, and I was on my way by lunchtime. They even informed me of an open recall item that I wasn’t aware of and took care of that at the same time! That was much more convenient than having to schedule an additional visit. Our service advisor Cory was courteous and professional.
BMW of Stratham went over & an over to accommodate me picking my car up & returning it when the service was done. I highly recommend their service department!
Great service at fair price. Appointment kept on time service updates received while I waited in comfortable waiting area well stocked with complimentary beverages and snacks.
I had an excellent experience with the dealership. My prior BMW x5 was purchased new less than a year ago and was totaled by a reckless driver hitting me. The thought of buying another car was pretty stressful, but I knew to reach out to Scot Murby since I had just worked with him less than a year ago.
I had a few things that were really important to me—the color, the driver-assist features, and the tow hitch—and I didn’t have the time to build something custom. Scot searched the country and was able to find a ... Read More DealerRater - Apr 27, 2026
I am fully satisfied with your service. I always remember my BMW service technician for their extraordinary job
Excellent service and communication between service advisor and the customer. I would recommend this dealership without reservation.
I had to take my X5 in after the engine light came on due to a prior accident and repair down in Florida. I am not a previous customer but they still worked with my insurance and the original repair shop to help me get the issue resolved promptly.

Always a good experience when I work with Paul in the Service Center, this time was no different
I had a very positive experience at BMW of Stratham. I stopped by near the end of the day to pick up brake parts I had ordered online, and while I was there, I checked in with the service department to get a quote for installing rear brake pads and rotors.
Even though Adam Webster was about to leave for the day, he still took the time to help me. He let me know about a brake special they were running, which ended up saving me money. Since my brake light was on, I was hoping to get the work ... Read More DealerRater - Apr 14, 2026

BMW of Stratham really came through for me when I needed them! I was traveling from Connecticut to Dover and had a tire puncture while on I95.

Very good customer service and efficient repair time. Also provides clear overview of the issues
The service here is always top notch very well organized, and the communication is outstanding very friendly environment
