What is a transmission overhaul?

By Mister Transmission

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.

Transmission 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.

I broke down just outside...
Norm Buda
I broke down just outside Richmond Hill 3 days before Christmas and dropped off my broken vehicle with Gary. I was on a spiritual journey across Canada and that was where things got put on hold. Slow down is the message.Long story short folks, Gary and his men gave it back to me first week of January and I immediately headed back to Alberta. I drove 4km on a rebuilt transmission, transfer case and universal joint replacement. I drove through some of the worst conditions I have ever done before and all the time didn't even have a single worry or thought about the work that was just done cause I just knew they were professionals and I was at peace. Thanks again Gary for your help. God bless you guys! Have a prosperous 2022.

Colin Puchala
Driving through Toronto from out of town we had transmission problems with our van. Ray at Mister Transmission was an absolute star!! After calling several places, I talked to Ray and he was very welcoming and said to bring it over and he would take a look. From the very beginning, I totally trusted his advice and he was accomodating considering our situation. He gave us the straight facts and information that we needed and truly helped us out. Too bad that we are not from the area as he would definitely be someone that I would trust with my vehicles and who would become our "go to" guy. Thanks Ray so much for your help!

Henri R
Excellent and quick service. Addressed the complaint I came in with and identified that it would be covered under warranty from a previous service. No charge and yet I wouldn't have known the difference had they charged me for the issue. I'm a repeat customer here and they have treated me kindly and provided very good service each time.
