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.

Had my transmission rebuilt and these guys did an amazing job! The quality of work exceeded my expectations. Thanks to Gus for explaining procedures, letting me know the labour cost upfront and what to expect in terms of cost when the transmission is taken apart. I commended Mr. Transmission for this; rebuilding a transmission is costly!

Susan Reynolds
Last week, on our way to a family reunion, we experienced trouble with the transmission and fluid leaking from rusty lines. We stopped at Mr. Transmission and experienced the best customer service! They worked hard to find the parts required and repaired our vehicle in a timely and cost effective manner! Kudos to the Mr. Transmission team! They could give lessons in customer service! Just an aside as we were struggling to move forward and find out what was even wrong with the vehicle, we pulled into Green & Ross. A person came out and expressed their concern that we were blocking their available and empty parking spots. They didn't seem to be interested in assisting us which is when we quickly decided to move on and we googled Mr. Transmission - a fantastic choice!
