If you can avoid ever having to rebuild your transmission, you’ll be better off for it. But that’s not always possible, so, when is a transmission rebuild necessary?
A transmission rebuild, also called a transmission overhaul, involves removing the transmission from the chassis and then taking it apart, piece by piece. At Mister Transmission, when we do a transmission rebuild, we carefully remove and examine each part of your transmission. When we find parts that are significantly damaged, we replace them. When we find parts that are still in good working order, we clean them in a special solution. As a matter of course, we replace the torque converter, all seals and gaskets, and all components that have friction surfaces, such as bands and clutches.
We also check for any manufacturer updates. Manufacturers sometimes recommend modifications to correct design flaws that were discovered after the transmission was built. Automobile manufacturers often provide upgrade kits to transmission shops to fix these design flaws.
Transmission rebuilds are major transmission repairs. Most repairs are not this involved, so to necessitate a rebuild takes a lot. This is for transmissions that are fully shot, completely overheated, damaged by a collision, or otherwise damaged to the point where most of the transmission no longer functions properly. However, rebuilds are not only performed on transmissions that are totalled.
Sometimes you need a transmission rebuild when the cause of your problem isn’t evident. Some parts of your transmission can be accessed while it remains in the body of your vehicle. These are accessible parts. However, there are many inaccessible parts in your transmission, as well. Sometimes a transmission is having problems because one or more of these inaccessible parts are malfunctioning. A transmission rebuild allows technicians to go searching for the problem parts which they can then replace as they find them.
If your transmission is so damaged that a technician is suggesting a rebuild, you basically have one other option: a transmission replacement. This involves replacing your transmission entirely with an old or “new” transmission. But these “new” replacement transmission are usually aftermarket transmissions built with new parts.
Replacing your transmission with an entirely different used one with an unknown provenance and questionable history might seem easier and faster, but it leaves a lot of open-ended questions. You don’t want mystery when it comes to your transmission. A rebuild ensures that every part in your transmission works properly.
At Mister Transmission, we offer both transmission replacements and rebuilds, and many other services. To learn more about transmission rebuilds, please contact us.
