Everything You Need to Know About Transmission Fluid Changes

Transmission fluid is (almost literally) the lifeblood of the transmission. An automatic transmission simply won’t work without transmission fluid. Now, you would have to have a very large leak to have absolutely no fluid in your transmission. However, you still need to have the right level and the right quality of transmission fluid or else you’re inviting transmission problems to happen. To have your transmission in perfect working order, you might require a transmission fluid change.

Transmission Fluid

Transmission fluid works as a lubricant and it is optimized for the functions of the transmission. These functions include valve operation, brake band friction, and the torque converter. Transmission fluid is required in all automatic transmissions. Some manual transmissions also use transmission fluid, but some use engine oil or gear oil.

Transmission Fluid Problems

Not all transmissions are the same; not even all automatic transmissions. But all transmissions experience wear and tear that can cause debris to collect in the fluid. Furthermore, there can be problems within transmissions that cause the fluid to be damaged or degraded, and this in turn can cause further problems.

And then there are leaks. Any transmission can fall foul of a leak. The key sign of a leak is a patch of reddish liquid that has collected underneath your vehicle as it is parked. Leaks have to be patched and the lost fluid needs to be topped up.

Symptoms of using Poor Quality Transmission Fluid

If the fluid in your transmission is lacking in either quantity or quality, you will begin to notice symptoms in how your transmission operates. You may experience a temporary delay while shifting gears. Your transmission may take a moment to register the gear shift. Your transmission might also grind or clunk when you shift. Alternately, your transmission might slip from one gear into another (usually neutral) which can be very dangerous. And without enough fluid, your transmission can become overheated.

Transmission Fluid Changes

You should periodically check your transmission levels using your dipstick. Sometimes you can lose some fluid without experiencing a leak. In this case, you can top of the transmission fluid yourself or you can bring it into a transmission shop for a top up.

Transmission fluid changes can sometimes be a bit more complicated. Typically a fluid change is required when the fluid has become degraded or burned. You might be able to tell this yourself. Normally, transmission fluid is translucent with a reddish hue. If your fluid is opaque and/or has a foul smell to it, it is probably damaged. Also, transmission fluid can pick up too much impure matter from wear and tear within your engine. If this is the case, it has probably been detected by a technician during a pan examination.

How Transmission Fluid Changes Work

You might be able to do a transmission fluid change on your own, depending on the type of transmission you have. But sometimes it is necessary (and always a lot easier) to bring it in to a transmission shop. Here, technicians can flush out the bad transmission fluid and change it with new, better quality fluid.

Mackenzie Spencer
Top notch service at this location. I had a very specific situation with the transmission in my car, they were comfortable with me bringing my own part & had it installed for a very fair price. Other locations gave me insane quotes, I was very happy with my experience with Chris. My silly little Honda CR-Z is good as new.

Gary at Mr. Transmission was attentive and thorough in diagnosing my truck, taking the time to properly test everything. He determined it wasn’t a transmission issue, didn’t charge for the diagnostics, and even referred me to a trusted local shop for the actual fix. Thank you!

Miguel Dixon
This place is the only place to go for your transmission. Service and level of knowledge is unmatched. Everywhere else I looked and checked third party reviews, warranties, prices. This place is unequivocally the number one transmission place to go in Alberta. Stu I talked briefly on the phone but he was very knowledgeable and helpful. Upon entering the shop was met by Stu and Joe. Both extremely friendly, knowledgeable all around. Great people to deal with. A gentleman in front of me was relaying a story that his in-laws had told him that Mister Transmission was the only place to take his truck for a transmission. As all my research I have come to the same conclusion because of reviews and their long-standing history. This place will take care of you properly. Help with financing if need be all around and not find a better place in Alberta. Maybe anywhere.

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!!

Sushil JK
I had a great experience getting my TCM and control arm replaced here recently. Even though the repair involved some cost, the team took the time to clearly explain everything in detail before proceeding, which I really appreciated. They thoroughly diagnosed the issues, dug into every possible cause, and made the necessary fixes with care and precision.After the repairs, the difference in driving is noticeable the car feels much safer, smoother, and more reliable. It’s clear they take pride in their work and focus on doing the job right rather than rushing through it. Highly recommend this place if you want honest advice and quality service.
