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.

Christy McMurray
Thank you, Mister Transmission! After taking my vehicle to the dealership where I bought it, and paying $150 for them to tell me what I already told them was wrong, the Dealer gave me a quote of $6,500 to replace my 9 year old transmission with a factory rebuilt one, because it couldn't be fixed or rebuilt by them. Thankfully I called Mister Transmission and Chris knew exactly what the issue was, how to fix it, and it only cost me $385 for everything and it was fixed in a day. I am so grateful that Chris and Dawn run an honest operation and provide genuinely great service. Thanks again!

Cambridge Mister Transmission was awesome. We ended up having a small issue but they still took the time to show me where on my vehicle the problems were and fully explain the possible issues. They were prompt in getting back to me the following day and I had my vehicle back in no time. Chris and Nick were amazing and the office is so clean and pleasant. Great customer service!

Chris Elmquist
Mazda 3 AT light came on one with some bad noises and clunking. Dealer said need a new transmission for only $4400. Took it to this and a quick check they determined it needed new TCM which is very common on the mazdas. They took care of it and even did a bunch of extra work fixing a wiring harness all for the cost of the TCM . cannot say enough about how we were treated by Chris and Dawn. Would recommend them. FIRST CLASS!!!!!

Kieran Massicotte
I took my differentials down to get rebuilt and Steve was very professional and the total was 200 bucks cheaper than the quoted price and there was a few things during the whole process that didn’t go as planned as I had brought all the bearings parts and some bearings were the wrong ones and I had brought 4.88s to put in end they would not work and before continuing with anything Steve would call and double check to let you know what needs to be done and get the ok from me first before they would continue overall amazing place Steve and the guys were awesome and the work was done perfect and the diffs have never been more smooth highly recommend.
