What Goes Into a Transmission Rebuild?

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.

What is a transmission overhaul?

transmission overhaul

As with many components of your automobile, the earlier you spot an issue with your transmission and bring it in for a repair, the greater the chance that the repair will be relatively quick and simple. Of course, it is not always easy to identify transmission problems nor can all problems be, “nipped in the bud”, so to speak. Nevertheless, it is always best to bring your vehicle in for an inspection and possible repair at the first sign of trouble.

If you don’t, (and, sadly, sometimes even if you do) you could be facing a transmission overhaul. A transmission overhaul is a very detailed and involved type of repair. Just what goes into it can be complicated, so this article will endeavour to explain the details of a transmission overhaul.

Transmission repair

The truth is that a great deal of transmission repairs can be done relatively painlessly. It’s impressive how many problems can be resolved by topping up or changing out the transmission fluid as well as maybe repairing a leak. But this is not a catchall; there are a number of transmission problems that this won’t repair.

Sometimes, a part needs to be replaced. Skilled technicians can often identify which part it is by running various tests and diagnostics, both physical and digital in the case of computer controlled transmissions. There are a number of parts that are accessible without requiring the removal of the complete transmission from the body of the vehicle.

The parts that are accessible, however, vary from transmission to transmission and most transmission repair facilities would hesitate to provide meaningful warranties on external repairs for the simple reason that they cannot see if there are any additional internal problems in the components that are only accessible by transmission removal. And of course, there are many parts that are not accessible. In these cases, you’re looking at a complete overhaul.

A transmission overhaul (also known as rebuilding a transmission) requires the removal and disassembly of the transmission in its entirety. Every part of the transmission is inspected for wear and damage, and then it is cleaned in a special cleaning solution, or 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 is also replaced, usually with a re-manufactured one. Technical service bulletins are checked to see if the auto manufacturer recommends any modifications to correct design defects 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 tell, a transmission overhaul is serious business. It is not a first resort nor is it a quick and simple job. Responsible technicians will only recommend a transmission overhaul if the problem your transmission is experiencing is a severe or unknown one. However, the plus side of a transmission overhaul is that it is so complete that it often prevents the development of any future serious transmission problems for a long time to come.
