How and When Should I Change My Transmission Fluid

Transmission fluid is the lifeblood of your transmission. Transmission fluid acts as a lubricant to help keep everything running smoothly and efficiently. That is, of course, assuming that you have good levels of clean transmission fluid in your transmission. To ensure this at all times, you should regularly change your transmission fluid. But how and when is sometimes a matter of debate.

Transmission fluid

There are many transmission problems that can be caused or exacerbated by an inadequate quantity or quality of transmission fluid. If you are driving around with either very old or not enough transmission fluid (or worse still, both), you are accelerating the wear and damage on components within your transmission. Taking the time to change it out when necessary could save you loads of time and money in the end by extending the lifespan of your transmission.

When to change your transmission fluid

Just when you should change out your transmission fluid will vary depending on what kind of transmission you have, what vehicle you drive, where you drive, how you drive, and how much your drive. But for a very rough estimate, for an automatic transmission, you ought to change your fluid every 50,000-100,000 kms. 100,000 kms is in the far reaches of the acceptable range, mind you. The Automatic Transmission Rebuilders Association suggests every 50,000 kms or every two years.

For manual transmissions, you should change the fluid about every 50,000-90,000 kms, however, under intense use, some manufacturers suggest changing it as often as every 25,000 kms. The reason for the difference between automatic and manual transmissions is because they take different fluids. Automatic transmissions take –get this– automatic transmission fluid. For manuals, it is a bit more complicated. They might take any of a variety of oils: regular motor oil, heavyweight hypoid gear oil, or even automatic transmission fluid in some cases. Your owner’s manual will tell you which is best for your transmission.

How to change your transmission fluid

To change out your transmission fluid, first let your car idle for a few minutes. After turning your ignition off, raise and secure the vehicle. Lay down at least a two-gallon catch pan, then carefully remove the bolts from one side of the transmission pan and then the other bolts, allowing the pan to tilt and drain. Once you’ve removed all the bolts, lower the pan and dump the remaining fluid into the catch pan.

After that, remove the old transmission filter and O-ring. The filter contains fluid, so keep the drain pan underneath. Install the new transmission filter, and make sure that the O-ring is in the appropriate place. Attach the new gasket to the pan with oil-soluble grease – not gasket sealer or adhesive.

Screw in all the fasteners finger-tight. Torque the pan bolts to spec in a spiral pattern starting at the center. Maximum torque is often about 12 pounds per foot. Then, lower your automobile and fill the transmission with the recommended amount of fluid. Finally, turn your engine on to check for leaks.

I went into Mister Transmission to have what I thought was a Transmission problem. It wasn't but they found the issue in no time being a transfer case and right front axel. Only the work required was performed. Could't be happier.

Went off-roading and had my Jeep fall into a giant mud hole that ruined the engine. Decided to take my Jeep to Off-road addiction in St Thomas who were going to do an engine swap. After 2+ months, they weren't able to complete the work nor figure out the issue. They said to take it into a dealership. Dealership quoted me $10k for a new transmission. Was recommended to checkout Mister Transmission and I wish I knew about them sooner.Pete was awesome to work with, he explained everything that was wrong, documented it and took pictures. Previously the engine and transmission weren't seated properly and had cracked the transmission pump. These guys were able to rebuild my transmission, put in a new transmission pump, seat the engine and transmission properly, and have the whole thing running properly with the quoted estimate in both cost and time. I was completely amazed by how quickly they were able to fix my issues.This is the only shop I'll take my Jeep in for any work done in the future. Last year I had my gear and pinion swapped from 3.23 to 4.56, again with flawless work and 0 issues.100/10 recommend you take your vehicle here for any servicing needs. These guys know their stuff and I'm happy to throw money at them any time I need work done.

Megan Wood
I called Georgio and told him that I was having an error message on my transmission. I brought my car to his shop and he diagnosed the problem. He told me that I should take my car to the dealership (Ford) as the issue should be covered under an extended warranty. Luckily, it was covered under warranty. Georgio did not charge me anything for the diagnosis and was very honest, professional, and kind. I would recommend him to anyone! Thanks again Georgio!!

Dylan Toutant
We've all dealt with the shops who nickle and dime us and cost us time and money only to be left with the same problem or worse, no ideas, and a large bill.Not here. They told me everything wrong, (even beyond what I initially thought i had identified) what they can and cannot do to remedy it, and empowered me to make the final choices on how to proceed with sound information and expertise which only re-asserts the quality of service received. To me this was the right place to bring my vehicle.DO YOURSELF A FAVOUR, and give them a call, (or email), and while I mostly spoke to Denise, literally anyone I spoke with there gave me the time of day and treated me and my vehicle with respect. This wasn't one of my shops before, but it is now.Thanks for the terrific experience and if I ever need to, I'd be happy to return.TL;DR This shop is worth the visit. Honest, upfront, quality service. Customer service professionals!
