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.

Jasbir Singh
Took my 2012 Nissan Altima to the dealer in Mississauga because the car wouldn't pick up speed properly. They said the transmission needed replacing and gave me an estimate that was really expensive. Another customer in the waiting area at the dealer recommended I try Mister Transmission so I called the store in Brampton because it was close to my work. I am very glad I did. They fixed my problem for a lot less and they were very professional in explaining what was wrong. I picked up my car 3 days ago and it is working great now. Thank you Mister Transmission.

If your looking for the best service and work ethic, in Alberta, these guys are it. Transmission shops are notorious for bad reputations. I own a 2003 custom land rover and trust it with basically no one but these guys now. I waited for 3yrs to find the right people to do the work. They not only did what I asked, but way over and above. Mel is an absolute pleasure to deal with.I was referred to Excel by Family that own Popo and Sons on Lacombe. Best advice in yrs.

Was convinced I had a transmission failure and was prepared for a big bill but they spent the time to diagnose that it wasn't transmission related. Let me know where to go with no charge. Very honest.

Colleen Whalley
Gary at North Bay transmission was amazing. My 2016 Rogue had some major issues. He was able to find a second hand one. These are common issues with the Nissans CVT transmissions. Which after speaking with Nissan doesn't seem to be a concern. Repairs all total $7600 plus rental $575. Gary ensured that i received their rate from Enterprise. It was suspected that the awd unit had leaks/issues. When I went back for the 10 day check after repair. It was confirmed the awd needed some repair. When I brought it back in for that repair. Gary did not charge me the cost of taking the unit out again. He absorbed the almost $600 i would have been charged. I was treated with respect and fairness! Their estimatex time frames for work completion were kept. Keep up the good work Mister Transmission in North Bay!

Renee Lauzon
It is a rarity when you come across an honest mechanic who puts looking out for your vehicles safety and longevity as well as the the owners best interests firsthand. Although I was not happy with the news that I received from Kris (honest mechanic) he did help me get my lemon (my SUV) on the road again and even offered to inspect my next used vehicle prior to purchasing it FOR FREE!!! When was the last time you received a diagnostic check on your vehicle without having to pay?I thought Kris was a straight forward, no BS, and very kind mechanic that everyone wit a vehicle needs!!! Thank you Mister Transmission, You are my newest BFF!!!🤗
