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.

Dirk Bag
I have waited a full year to leave a fair review.Got me a 2018 Ford F150 with that faulty 10 speed that started to act up. I called 2 or 3 transmission shops that quoted thousands above, 1 nearly doubled what this shop quoted and 1 shops that said they will not work on this transmission... unbelievable..lol.Took it to Mr. Transmission and got it rebuilt. This truck runs like new now, better than new imo. I even went to test drive a newer 2020 model with much lower kms to compare and that one didn't shift as well as my 2018.Amazing transmission shop!Thank you!!

Recently I received a van off of a family member and it wasn’t shifting properly. The RPM’s were running high, and it was running a bit rough, so I called Mister Transmission in Lindsay and had the pleasure of speaking to Jim. I explained to Jim what had been going on, and he was quick to assist me and give me ideas of what could be happening. The next day I received a call, and Jim had told me the problem and the estimated range of cost for repair.Jim is an honest and reliable transmission mechanic, he fixed my vehicle up for me and told me in great detail what was happening with it. Knowing how expensive and tedious some transmission repairs can be, he saved me a lot of money with his knowledge on my vehicle.I would recommend taking your vehicles to Mister Transmission in Lindsay and I for sure will be back if I have any transmission problems in the future. My van is now running great thanks to Jim at Mister Transmission in Lindsay.
