Why Is It Necessary To Change Your Transmission Fluid?

Why Is It Necessary To Change Your Transmission Fluid?

Do you really have to change your transmission fluid or is it just one of those things that you’re supposed to do. We hate to tell you, but, yes, you do have to change your transmission fluid at some point to ensure a properly functioning transmission.

What Is Transmission Fluid?

Your transmission fluid is the lifeblood of your transmission. Most Canadians drive automatic transmission vehicles, which require automatic transmission fluid to lubricate the components within the transmission and it also acts as a coolant. Continuously variable transmissions (CVTs) also use transmission fluid. Manual transmissions vary. Some use transmission fluid, some use something called transmission oil, and some use standard motor oil. Automatic transmission fluid is optimized for automatic transmissions, but all these fluids provide lubrication.

What Problems Might You See With Your Transmission Fluid?

Checking your transmission fluid every month gives you the best chance of catching small problems before they grow big. But what are you checking for? First, check your fluid levels. If your fluid isn’t at the line, top it up. If you have to top it up every month, you probably have a leak, and your transmission needs to be resealed. But also check the quality for your transmission fluid. It should be mostly clear with a reddish hue (or in some rare cases, greenish). If your fluid is opaque or if it smells bad, then this is indicative of a larger problem. Apart from whatever other repair is necessary, your transmission fluid will need to be changed.

Do You Only Need To Change Your Transmission Fluid When There Are Problems?

If your transmission overheats, it can burn your transmission fluid. Burnt transmission fluid needs to be changed. To check your transmission, a tech might perform a pan examination, in which they will check your fluid for particulate matter. Some material in your fluid is normal, but there shouldn’t be a lot of it. Friction surfaces often wear down and, if left alone for too long, they’ll contaminate your fluid to levels that are too high. Then your fluid will have to be changed.

All these issues that require transmission fluid changes start somewhere else. But do you need to change your transmission fluid just as a precaution? Some manufacturers offer “fill-for-life” fluids and some transmissions are designed to be complete systems in which nothing goes in or out. But claiming something doesn’t make it true. No matter what kind of automatic transmission you drive, what kind of fluid you use, or where you drive, the Automatic Transmission Rebuilders Association recommends a transmission fluid change every 50,000 kms, or every two years.

We went to Mr. Transmission thinking there was an issue with our trucks transmission. Bryan was so honest and transparent - told me that my trucks transmission was absolutely fine and actually told me what the problem was. I appreciate his honesty and kindness! You don't always find that kind of service but when you do, it definitely needs to be recognized! 100% recommend! Thank you again!

Had a wonderful experience at the Dixie Road location managed by Aki Sahaye. My very first impression from speaking to him on the phone was that he was very respectful. I met him when I took my vehicle to his shop, and I must say, he is a very sincere and caring person. He takes pride in his work and the employees' work, and what he delivers in terms of customer service and satisfaction. He was very patient in explaining the details of the issues, and he and the few staff member I saw were all very courteous and friendly. They constantly kept us updated with their investigations of the problems, advice and estimated cost. We were expecting that we would have to do an entire change over of the transmission, but it was the sensor, battery and oil leak issue. They were honest indeed in advising of the issues. Aki was very reassuring, in terms of contacting them back if I have any problems, and I was given 3 months warranty on the work done. They looked at the vehicle very quickly and within three days I got back my vehicle as they had to order a part from the dealer and wait for it. They were expensive, but the trust, reliability and other factors mentioned above have to be taken into consideration. I left there with a feeling of being treated and respected as a family and would definitely recommend them for any transmission issues.

Leanne B
We brought our Rav4 to Mister Transmission after receiving contradictory diagnostics from the dealership, The two people that helped us out were thorough and direct with their review of the car and plan moving forward. They didn't jump to the most expensive solution and found smaller steps to solve the problem.
