5 Common Automatic Transmission Problems

Transmission problems can be a real hassle. If your muffler isn’t working properly or if you’re tires are not properly pumped up, these are problems that should definitely be attended to as quickly as possible, but they’re unlikely to ruin your whole day. A problem with your automatic transmission, however, that can cancel all your plans for an extended period of time. It can also be very dangerous. But knowledge is power, so let us arm you against potential automatic transmission problems by discussing five of the most common problems, their causes, and their solutions.

  • Insufficient Levels of or Degraded Transmission Fluid

This is perhaps the most common problem, but if it is caught early enough, it can also be the easiest to fix. Transmission fluid is the lifeblood of the transmission. An automatic transmission cannot work properly without enough transmission fluid. Furthermore, that fluid needs to be of a sufficient quality.

The truth is that there is no automatic transmission problem that cannot be caused or exacerbated by a lack of quality transmission fluid. Checking and topping up one’s transmission fluid is a very easy and painless process. You can do it yourself or bring it into Mister Transmission and we can do it for you. However, if you’ve perceived problems with your automatic transmission, the first thing you should do is check your fluid.

Sometimes a transmission will have the correct level of fluid but the fluid itself will be degraded. Good fluid will be a reddish, translucent colour. An unpleasant odour or discoloration indicates that the fluid is no longer in good shape and/or there are other problems with your transmission. Mister Transmission can remove your fluid and replace it with new fluid if we suspect that is the problem.

  • Slipping

Automatic transmissions sometimes have the problem of slipping. This happens when your transmission “slips” out of one gear and into another. As you can imagine, this can be a very unnerving, annoying, and even dangerous problem. Slipping transmissions also often cause the vehicle to have trouble accelerating.

As mentioned above, a slipping transmission can be caused by a lack of transmission fluid. This should be easy enough to fix, but this problem could also indicate a more serious problems. A slipping transmission could also be caused by worn out or broken transmission bands, clutches or gears or by solenoid problems.

  • Grinding

Grinding is the opposite problem of slipping. An automatic transmission will sometimes grind when you try to shift gears, making it difficult to do so. Interestingly, a grinding problem can be caused by all the same things that can cause a slipping transmission.

  • Noises

It pays to listen to your transmission. Generally, it should not be very noisy. Unusual and especially loud noises are often a sign of a problem with an automatic transmission. If you shift the gear to neutral and it’s still noisy, you likely have a transmission problem. Also, keep an ear out for whining, clunking, and humming.

  • Check Engine Light

If your check engine light is flashing, please don’t ignore it. Bring it to your local Mister Transmission for a free multi-check and diagnosis as it could indicate an automatic transmission problem.

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.
