When to Change your Transmission Fluid

When to Change your Transmission Fluid

“When do I need to change my transmission fluid?” It’s one of the most common questions that we get asked here at Mister Transmission. It’s a good question to ask. Your transmission fluid is vitally important to the wellbeing and efficacy of your transmission. But the answer to that question is nuanced; there’s not one simple answer. However, this article will attempt, in the broadest terms possible, to describe the times and situations when you should change your transmission fluid.

Checking Your Transmission Fluid

Your transmission fluid is important for two reasons. First, your transmission won’t work without it, so that makes it pretty important. Depleted or degraded transmission fluid can damage your transmission and reduce its efficiency. But beyond that, your transmission fluid is key to demonstrating if you have a transmission problem. For example, if you have degraded transmission fluid then there is probably something wrong within your transmission to have caused this.

That is why checking your transmission fluid is key to maintaining your transmission. You should check your transmission fluid every month. Use your dipstick to check your transmission fluid levels. If it is low, top it up. If you find that you’re topping up your fluid every single month, you probably have a leak somewhere. Good transmission fluid is reddish-clear and has a neutral odour. Foul smelling and/or opaque fluid is a sign of a problem. If you see such fluid during your transmission check, you should bring your vehicle in to have your transmission fluid changed and to have your transmission checked for problems.

Multi-Check

Sometimes there are issues with your transmission that you can’t tell by yourself. This is why bringing your vehicle in for regular transmission service is important. At Mister Transmission we provide a Multi-Check Inspection, an exhaustive inspection of your transmission. The last step of the Multi-Check Inspection will determine the condition of your transmission.

Regular Transmission Fluid Changes

Some transmission manufacturers boast that the fluid in their transmissions need never be changed because it is a completely closed system. These claims don’t stand if there is something wrong with your transmission, though. Even so, sometimes transmission technicians will recommend changing the fluid in such transmissions anyway, just to be safe. Most auto manufacturers recommend changing your transmission fluid every 45,000 to 90,000 kilometres. That’s a big range. At Mister Transmission, we recommend erring on the smaller side of that range. If you regularly drive in harsh conditions or drive a truck that tows material, you will probably want to change your transmission fluid even more frequently than that,

Ultimately, every vehicle, transmission, and drivers are different. There is no universal rule that pertains to all vehicles, so ask your transmission technicians what they think. If you notice that your transmission fluid is damaged, have it changed and have your transmission inspected. If you’ve gone 45,000 kilometres without incident, you might as well have it changed just to be safe.

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.
