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.

Contact Us

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.

Kevin Hnatiuk
Blair and his team at this location seem to be the go-to for known and unknown transmission types and were recommended by another mechanic shop. For example, I needed to replace a transmission on a 2003 Right-Hand-Drive (RHD) Hybrid Toyota Estima I imported and they were able to swap it out. I appreciated that someone in the city was willing to get creative and not turn me away because it wasn't part of a pricing template.During a more recent visit, I needed a diagnostic for a Used Nissan Pathfinder I had purchased and requested a CVT fluid change. The diagnostic returned a faulty Mass Air Flow sensor. The front desk (Darren) went with an OEM sensor ($600) versus one of the $200 sensors you find on Amazon and his rationale for doing so seemed sound as many of the reviews showed that oversea-sourced sensors from Amazon fail within a year.Perhaps I'm of a more curious nature than most, and I have plenty of questions about the work being performed, what's being used, and the condition of the fluids being removed. I appreciate when shops help me understand their rationale. Darren is a pleasant-enough fellow, however, I did not feel on my last visit that we were in sync when I was seeking information on the condition of my transmission and fluids. At one point I was told that, "Curiosity killed the cat," which I found an odd response to a straightforward question. I'll chalk it up as a misunderstanding. My advice to this location is that a little information goes a long way to reassuring the customer. If Darren had been a bit more curious about the work being performed, I would have felt in a better position to say it was money well spent. My vehicle doesn't drive or perform any different since having the sensor and CVT fluid changed, so in my case, I would have welcomed a confident accounting of the condition of the fluids and work. Dare I suggest photos as some of the other shops are now doing. I'm glad we have Blair and his mechanics here in the city doing the work they do. My suggestion for improvement is that they modernize some of their process and systems (eg. photos on file) so that customers like myself can feel reassured throughout the interaction and beyond.

Great service, very transparent pricing. They kept me in the loop through the entire process with updates, got my transmission rebuilt in about a week. Warranty was the big reason I went with them.
