Why You—Yes You—Need To Check Your Transmission Fluid!

Why You—Yes You—Need To Check Your Transmission Fluid!

Checking one’s transmission fluid is an integral part of vehicle ownership. If you don’t check your transmission fluid regularly, you are not taking the best care of your vehicle. So, check your transmission fluid!

“Do I Need To Check My Transmission Fluid?”

Yes, you do. Automatic transmissions require transmission fluid to operate properly. Without the right level and right quality of transmission fluid, you are damaging your transmission every time you drive. Manual transmissions can also use transmission fluid or transmission oil mostly for lubrication.

“When Should I Check My Transmission Fluid?”

When was the last time you performed a transmission fluid check? If you have to think about the answer for more than six seconds, it has probably been too long. In that case, you should check your transmission fluid right now.

“How Often Should I Check My Transmission Fluid?”

We recommend checking your transmission fluid once a month. Ideally, you will not have to do anything beyond checking your fluid when you do. Transmission fluid should not have to be topped up every month. However, by checking every month, you’re increasing the chances that you can identify the beginning of a transmission problem before it grows into a major transmission problem.

“What am I checking my transmission fluid for?”

You are checking your transmission fluid for two things: quantity and quality. On transmission models with dipsticks, the procedure is simple. First, most models recommend that your vehicle should be running while you check transmission fluid, so turn on your vehicle and make sure it is in park with the parking brake on. Locate your dipstick, wipe it off with a rag, and insert it into the tube where you pour your transmission fluid in. Then remove the dipstick. There is a line on the dipstick. If your fluid level is below that line, it needs to be topped up. If you have to top it up every month, you either have a leak or another problem.

To check for your quality, you need your eyes and your nose. How does the fluid look? Healthy transmission fluid is largely clear with a reddish hue. Now give it a smell. Healthy transmission fluid is largely odourless. If your transmission fluid is opaque and/or foul smelling, something is wrong with your transmission. You should bring it in to a transmission shop for service as soon as possible.

Mister Transmission

Checking your transmission fluid is not difficult if the type of transmission you have has a dipstick.  If not, the vehicle needs to be inspected on a hoist by a Mister Transmission trained professional. We can also investigate any issues you notice with the way your transmission is operating. Please contact us to learn more about our services.

Brian Jones
So, I take my truck into Mr. Transmission in Orillia, for an assessment, because I thought I heard some noises when it was shifting gears. He takes it out for a test drive and hooks it up to the computer. Spends a half hour with my truck. Comes back and tells me it’s in perfect running condition. Says nothing comes up on the computer. I ask him if there’s any maintenance I can do he says “no nothing”. Ask what I owe him and he says “Nothing”. I want to give him 20 bucks at least... he won’t take it. That’s honest service. The least I can do is give him a good review!

Angela Lee
Excellent experience. My car was throwing transmissions codes and the mechanic shop recommended Mister Transmission for a specialist to look at. These guys know what they are doing. They knew right off the bat the possible issues and were able to recommend my next steps. Turns out my transmission wasn't causing issues, but it was more of a engine problem. Thanks again for for all your guys help! Cutest worker Pepsi was on duty and she did a great job of entertaining me. Highly recommend to check these guys out if your car is having tranny issues/codes!
