Facts About Transmission Fluid

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.

糖糖
I brought my Range Rover Evoque in with tricky “Gearbox Fault” and “Traction Reduced” warnings. Other shops could not pinpoint the root cause. Bobby at Mister Transmission was very knowledgeable and took time to run full proper diagnostics.It turned out the issue was caused by a faulty battery. Even though they do not perform battery replacement on‑site, Bobby immediately helped me connect with another suitable specialist shop. He carefully communicated all my vehicle symptoms and concerns to the other shop on my behalf.Bobby and his partner were gentlemanly, friendly and extremely patient throughout the whole process. He provided a transparent upfront estimate before starting any work, explained everything honestly and never pushed unnecessary expensive part replacements. Communication was smooth, and I am really grateful for their help. Fair‑priced and professional service. I would definitely recommend Bobby and this location.
