Facts About Transmission Fluid

Transmission fluid is the lifeblood of your transmission. Your transmission requires fluid to operate properly. Without fluid, it won’t work. It’s as simple as that. But transmission fluid itself can be quite complex. It can tell you lots about your transmission’s health and efficiency. If you know how to read it. That’s why transmission fluid is so important to transmission service. Not only must the fluid be serviced itself, but it can also indicate what else in your transmission might require service.

Transmission fluid

Let us begin with the basics. What do most people know about transmission fluid? They know that it’s the fluid that works in the transmission to keep it operating properly. Every transmission needs fluid. As such, they know that patches or streams of fluid underneath their vehicle is certainly not a good sign. Such a sight indicates that your transmission has sprung a leak and requires service immediately.

Furthermore, most people (we hope) know that transmission fluid should be changed regularly. At Mister Transmission, we can change your transmission fluid for you as part of the routine transmission service that we offer. Changing your fluid will help ensure that your transmission keeps running at optimal levels for years to come.

Frequency

Everybody wants to know how often they should change their transmission fluid. But of course, there is no one answer to this question. Just how frequently you should change your transmission fluid depends on the make and model of your vehicle, how much you drive, where you drive, and a number of other factors. You should consult your vehicle’s owner’s manual for more information, or you can bring in your vehicle for transmission service to Mister Transmission and we can help you figure it out. For a very rough number, the Automatic Transmission Rebuilders Association recommends changing your transmission fluid about every 50,000 kilometers or every two years. But again, this is just a rough estimate.

Pan examination

As part of our transmission service, we at Mister Transmission perform a multi-check inspection. In doing so, we examine multiple facets of your transmission for problems. Including your transmission fluid. If the the fluid is a clear red colour, your transmission is probably working well. However, discoloured fluid and/or fluid with an unpleasant odour indicates that your transmission has experienced wear and damage.

As part of our pan examination, we check for metallic particles and friction material. We expect to find these in all transmission fluid, but an inordinate amount of particles or material indicate wear and damage. As part of our transmission service, we will survey the amount of particles and material present in the fluid and then determine further action from there. If a minor adjustment cannot fix the problem, we will suggest an inspection service to determine exactly what is going wrong inside your transmission.

If you have concerns about your transmission’s fluid or would like to know more about transmission service in general, please get in touch with us today. We will do our best to have your transmission up and running perfectly in no time.

Karla A.
I had a great experience trusting Mr. Transmission to make the rebuild of my 2020 Ford explorer Transmission. I was desperate about the car issue at the beginning, because it was a serious and costly issue, but Julie was very regardful, she took the time to explain all the costs and procedures until the car is fixed. She also was very patient with me and my husband because we had to take our time and figure out if would be worth to fix or just sale it the way it was, once we decided to fix, it was a matter of 8 days to have the transmission completely rebuild. The car is working perfectly as it was before the issue and I really recommend them to take care of any transmission related issues. Thanks Mr. Transmission

Kirsten Hasler
amazing experience! I recently brought my 2018 GMC Sierra to Mr. Transmission, Matt was amazing to deal with, my truck was having issues with the torque converter shutter over 100km/h and a hard shift between 1st and 2nd gear. Matt and his team did a rebuild on the transmission, explained everything in detail and had different options and they were extremely patient and understanding when it came to warranty, and picking/dropping off the truck! definitely a happy customer!!!!
