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.

Christy McMurray
Thank you, Mister Transmission! After taking my vehicle to the dealership where I bought it, and paying $150 for them to tell me what I already told them was wrong, the Dealer gave me a quote of $6,500 to replace my 9 year old transmission with a factory rebuilt one, because it couldn't be fixed or rebuilt by them. Thankfully I called Mister Transmission and Chris knew exactly what the issue was, how to fix it, and it only cost me $385 for everything and it was fixed in a day. I am so grateful that Chris and Dawn run an honest operation and provide genuinely great service. Thanks again!

Cambridge Mister Transmission was awesome. We ended up having a small issue but they still took the time to show me where on my vehicle the problems were and fully explain the possible issues. They were prompt in getting back to me the following day and I had my vehicle back in no time. Chris and Nick were amazing and the office is so clean and pleasant. Great customer service!

Mazda 3 AT light came on one with some bad noises and clunking. Dealer said need a new transmission for only $4400. Took it to this and a quick check they determined it needed new TCM which is very common on the mazdas. They took care of it and even did a bunch of extra work fixing a wiring harness all for the cost of the TCM . cannot say enough about how we were treated by Chris and Dawn. Would recommend them. FIRST CLASS!!!!!

Kieran Massicotte
I took my differentials down to get rebuilt and Steve was very professional and the total was 200 bucks cheaper than the quoted price and there was a few things during the whole process that didn’t go as planned as I had brought all the bearings parts and some bearings were the wrong ones and I had brought 4.88s to put in end they would not work and before continuing with anything Steve would call and double check to let you know what needs to be done and get the ok from me first before they would continue overall amazing place Steve and the guys were awesome and the work was done perfect and the diffs have never been more smooth highly recommend.
