How Do You Rebuild A Transmission?

The decision to rebuild a transmission is not to be taken lightly. While a fascinating process, rebuilding a transmission is not a quick fix. It should only be undertaken when absolutely necessary.

The Majority Of Transmission Problems Are Relatively Minor And Do Not Require A Transmission Rebuild.

Just as you don’t require surgery for a head cold, your transmission won’t need a rebuild for most of the issues it’s likely to face. There are so many problems caused by a lack of transmission fluid that it’s almost comical. That’s all the more reason to check your transmission fluid levels every month and top them up when necessary. Newer transmissions are computerized, which makes them run more efficiently, but does add something else that can go wrong. Top of the line transmission shops have technology that can interface with a vehicle’s onboard computer which allows for quick diagnoses and fixes.

Occasionally, parts of your transmission will probably have to be replaced. But don’t fret, this is not the end of the world. Often, parts that need to be replaced can be accessed while the transmission is still in the body of the vehicle. These are referred to as accessible parts. When an inaccessible part needs to be repaired, then we get into larger transmission repair jobs. But even in these cases, if the problematic part can be easily identified it can still be a relatively quick job. Then there are transmission rebuilds.

You Only Need To Rebuild A Transmission When There Is Extensive Damage Or If The Transmission Technicians Cannot Identify The Cause Of Your Transmission Problem.

Extensive damage or a complete transmission failure can necessitate a transmission rebuild. This involves removing the transmission from the chassis and examining each and every part for damage. Depending on its condition, each part is then cleaned in a special solution or replaced with another part. Parts that have friction surfaces, such as bands and clutches, are replaced regardless, as are all seals and gaskets and the torque converter.

Is It Better To Rebuild A Transmission Or Replace It Piece-By-Piece?

If the description above makes rebuilding a transmission sound labour intensive, that’s because it is. Wouldn’t it be much quicker and easier to simply replace the transmission with another one? It would but, in most scenarios, we advise against it. You would be replacing your transmission with a used one with an unknown provenance which could create a whole new set of problems. And “new transmissions” are extremely expensive compared to a rebuilt transmission.
