What Goes Into a Transmission Rebuild

The transmission rebuild is a specific kind of transmission repair. For many transmission problems, the necessary solution is a relatively simple one. Maybe a change of transmission fluid or switching out a solenoid pack. Unfortunately, however, not all transmission jobs can be done so swiftly. Sometimes, a transmission rebuild will be necessary. So what goes into a transmission rebuild?

Transmission repair

As mentioned above, the transmission rebuild is one of only many types of transmission repairs. It is also the most involved type of transmission repair. It’s a type of repair that is not meant to fix every problem. Many problems do not require such an endeavour. A transmission rebuild is necessary either when the cause of a transmission problem cannot be accurately identified or when the damage that a transmission has incurred is total or at least far reaching.

Transmission rebuilds

The first step in a transmission rebuild is the complete removal of the transmission from the body of the vehicle. This is necessary when the part that is thought to be causing the problem is not accessible while the transmission remains within the body of the automobile. When the suspected problematic part is replaced, this might solve the problem. However not all problems are solved so easily.

In some cases a complete rebuild is required. A complete rebuild consists of the removal and disassembly of the transmission in its entirety. Every part is inspected for wear and damage, and then it is cleaned in a special cleaning solution, or it is replaced with another part depending on its condition. Parts that have friction surfaces, such as bands and clutches, are replaced as are all seals and gaskets. The torque converter should also be replaced, often with a re-manufactured one.

Technicians will also check technical service bulletins to see if the auto manufacturer recommends any modifications to correct design flaws that were discovered after the transmission was built. Automobile manufacturers often make upgrade kits available to transmission shops to resolve these design defects.

As you can see, the transmission rebuild is a significant undertaking and takes hours of labour to complete. But it is a holistic approach; any problems your transmission has been experiencing are bound to be addressed through this process. The transmission rebuild should add a number of years on to the life of your transmission.

Rebuild or overhaul

You may have heard of transmission overhauls before. If so, you’re probably asking yourself what the difference is between a transmission rebuild and a transmission overhaul is? Well, that’s a simple question to answer. A transmission rebuild is a transmission overhaul; they mean the same thing.

If your transmission requires a rebuild, you have two options. The first is to remove your existing transmission and rebuild it, then put the rebuilt unit back in your car. The second option is to replace your existing unit with another unit that has already been rebuilt or re-manufactured.

However, used transmissions often have questionable histories that could create a whole new slew of issues. New transmissions, meanwhile, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts.

After a catastrophic failure of the CVT in my 2013 Subaru Outback I was glad to find such Professionals. Chris, Janna and the Technicians went above and beyond to get my vehicle back in service. Due to Covid-19 restrictions I had to send the Outback to Moncton on a flat deck. All the time it was there I was kept up to date on their every move and diagnoses. From the first Phone Call until I picked it up there was no doubt "This was the right place". Thanks again Mister Transmission !!!
