How to Change Transmission Fluid

By Mister Transmission

Determining the frequency of transmission fluid and filter changes hinges on many factors

Transmission fluid: it is the lifeblood of your transmission. Without it, your vehicle would cease to run. You need to have the transmission fluid and filter changed at recommended intervals as per your vehicle’s owner’s manual, and a transmission flush ought to be performed at least once every three years.

Transmission fluids serve three purposes: it serves as the hydraulic element within the transmission regulating gear changes, it keeps the transmission clean and lubricated, and it cools the entire transmission system.

There is a lot of friction happening within the transmission. These mechanisms are designed to work with the full capacity of transmission fluid. If the levels drop, that friction is less productive and more damaging. Over time, heat will break the fluid down and be unable to lubricate the system effectively. That puts pressure on the transmission to work harder to pump fluid through the filter.

Checking Your Transmission Fluid Level

If you are experiencing performance issues with your vehicle, you may wish to check your car’s transmission fluid level. But be advised: checking your transmission fluid level can be risky as you need to keep the engine running.

Moreover, in some modern vehicles, it is no longer possible for the average motorist to perform a transmission fluid check. It is advisable to have trained, experienced transmission technician inspect your transmission and the quality of the fluid in it.

Though your vehicle’s owner’s manual will make recommendations as to the required frequency of changing the transmission fluid and filter, you should also weigh the type of driving you do, and the environment where you drive. If you have high mileage on your vehicle, drive in mountainous or hilly terrain, regularly tow a trailer or boat, or if you’re hauling heavy loads, have your transmission inspected annually.

Preventative Maintenance Is Your Best Protection

Although there are no guarantees you can avoid a transmission failure no matter how well you treat your vehicle, you can reduce the risk of a transmission malfunction by ensuring preventative maintenance is performed regularly by a professional.

For more than 50 years, Mister Transmission has kept Canadian motorists on the road by ensuring the transmissions in their vehicles are in tip-top shape. If you have a question about your transmission or want to book a service appointment, contact the Mister Transmission service centre nearest to you.

My transmission failed on my Nissan Xterra Pro 4X last week. I called around and a lot of places would not even do the job, I was referred to this shop by a few friends. Spoke to Blair on the phone. Really great service, they did a great job in a very reasonable time frame and the price was fair also. Would come back again for sure

Meredith Armstrong
Mark from Mr.Transmission was absolutely awesome to deal with. After having transmission problems multiple times, he was able to fix everything 100% and with what was able to go through warranty, he did. My truck was not easy to deal with, so his patience level was amazing. I wouldn't go anywhere else for transmission problems in the future.

Darren James
Wes and crew did a great job tracking down and repairing an unusual transmission leak for me. Obviously knowledgeable, they were also persistent, adaptable, and skilled. Rather than rack up a huge bill without keeping me in the loop, Wes made sure to keep me informed and gave me the choice of continuing with previously unplanned (and potentially expensive) repairs or calling it a day. He was also very keen to make sure I understood exactly what had gone wrong and what was needed to fix it, and the extra effort he took to demystify the problem and the solution was very much appreciated. I hope that I won’t need any more transmission repairs in the future, but if I do I would not hesitate even for a second to bring it directly to this crew. Top marks!

I thought my transmission was going.(it had been slipping) so I took it to Mr Transmission on Centennial spoke to Dan. I was in absolute hysterics! Dan calmed me down and told me not to worry he would take care of it. When he came back he told me all it needed transmission fluid. I can't tell you how much I appreciated the honesty and understanding. I'm sure I wasn't the first person nor the last to come in loosing their cool. I will recommend Mr Transmission to anyone . Thanks Dan.

Denise Ruck
I'm a single mom. My transmission blew before Christmas. The staff were empathetic. They understood how much stress this caused me. Customer service was outstanding. They were honest and extremely helpful. Payment plans were an option that helped a great deal. They called me with updates and were honest with their work and their pricing!!! No surprises. Thank you, Mr. Transmission. Great experience. D. Ruck
