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.

These guys have been the best to work with! When I needed a new transmission, they squeezed me in and got me back on the road in no time. Then when I had trouble down the road with said transmission, they again got me in quickly and back on the road in only a couple days.They went over and above guaranteeing their warranty and I wouldn’t hesitate to refer anyone. They were nothing but helpful and understanding. This a place where they’ve got you covered for whatever tranny troubles you may be having.👍👍👍👍👍

I brought my vehicle here...
Olivia Blum
I brought my vehicle here for a second opinion after my regular mechanic said it needed a new transmission. They were able to find a service bulletin for a reprogramming and suggested I get that looked at first. It is sometimes hard to find a mechanic who doesn’t take advantage of women/people who don’t know much about cars. However, their suggestion saved me $5000 when they could have just told me I did in fact need a new transmission and done the work themselves. I am very grateful for the honesty and customer service at Mr.Transmission and would recommend them to anyone who asks!
