What Is an Automatic Transmission Rebuild?

Learn how an automatic transmission rebuild works, when these rebuilds are necessary, and the benefits of a rebuild over a complete transmission replacement.

What Is An Automatic Transmission Rebuild?

An automatic transmission rebuild, also called a transmission overhaul, is the meticulous rebuilding of a transmission piece by piece. Rebuilds are necessary when a transmission has experienced a catastrophic failure. When a transmission is thoroughly damaged, a technician may decide that replacing a few parts won’t solve the problem. Sometimes technicians can’t find the source of a problem, and so they need to inspect every component within the transmission.

In such scenarios, a technician might give you two choices. They’ll say they can replace your transmission entirely with a completely different one, or they can replace each damaged part individually. Many car owners initially prefer the transmission replacement option. It’s simpler, and it seems like it should be faster. At Mister Transmission, our technicians usually recommend a transmission rebuild, though.

Why Is A Transmission Rebuild Better Than A Transmission Replacement?

Replacing a transmission with a totally new one seems like a great option, until you realize that, despite how they’re marketed, these transmissions are rarely ever “new”. They’re typically aftermarket transmissions that have been rebuilt themselves. You don’t necessarily know where they came from and who did the work. And you certainly don’t know the provenance of each individual part. These components may not even be compatible with one another.

If you replace your transmission, you really don’t know what you’re getting. This can cause major problems in the future. Why replace a broken transmission with another malfunctioning one? It doesn’t make sense. That’s why we typically recommend a transmission rebuild to our clients.

The Process Of Rebuilding A Transmission

When the technicians at Mister Transmission perform a rebuild, they remove the transmission from the body of the vehicle and take it apart piece by piece. They inspect each individual part. They replace damaged parts and clean the operational parts in a special solution. As a matter of course, they replace all parts that have friction surfaces, such as bands and clutches, as well as all seals and gaskets. They also replace the torque converter, usually with a remanufactured one. At the end of a transmission rebuild, you have an automatic transmission that may not be completely new, but it’s at least one that’s completely certain to function properly. It’s a lot of work, but it gets the job done.

Tim V
Had outstanding service from this shop, particularly the Manager George S. who is about one the nicest individuals you will ever meet. He put me at ease for what was suspected to be a very large issue as diagnosed from another shop. In the end, it was another issue entirely, one significantly more affordable than expected. George was prompt with follow ups, went the distance to find a new part, and had me back on the road in a few days. George is a gem, and the work done at the shop was top notch. Highly recommend for any transmission/driveline issues.

Would like to say I was pleased with the service I received. They towed my vehicle in as I was unable to get it in under its own power. I assumed it was a transmission or transfer case issue, but it ended up being a broken axle that caused my grief. After they were able to get it rolling again they did a courtesy check of the engine / drive train to make sure they didn't miss something else, and noted a couple of other items that could become bigger problems down the road. They were able to repair those for me as well. Darren was very professional and polite. They got the truck in and out in a very respectable time frame, and they were very close to the estimated cost when I was paying the bill. I actually paid a couple C notes less. Overall would recommend you guys, as you do more an just transmissions, you guy take care of it all. Thanks again!

We had purchased a used honda civic from a used car dealership for our son to commute to university. Just our luck not even 3 months later a check engine light was on as well as a flashing D light and check transmission on the information Center console. We had taken it to a reputable dealership on Mapleview drive to get it diagnosed, after a full service that included a transmission fluid service the technician told us that he would erase the code and if the code came back to find a transmission shop . Well the code came back! I had called several local garages and was told that they don’t work on Honda civic C V T transmission. Luckily I called “Al” at (mister transmission Barrie) I told “Al” the history and he said to bring the civic to Essa road location and where he can diagnose it for free . Al gave me an Honest diagnosis with a break down of how much it would cost . And within a week we had a total rebuilt transmission and I feel he was a trustworthy person to deal with no matter what transmission problems you have even if it’s a Honda C V T .

Burak Ozbek
So i was basically trying to figure out if Honda CVTs were reliable. I was doing research and decided to call this place to see if they could humour me briefly. The guy i spoke to, cant remember his name, 43 years old, very friendly, told me everything i needed to know, clearly takes customer service very seriously and was willing to HAVE A CONVERSATION which no one does anymore. Will be going here for everything from now on. And if you want to know, without insulting other car makers, toyota and honda are the usual suspects for reliable CVTs.
