Replacing and Overhauling Transmissions

Replacing and Overhauling Transmissions

Many transmission problems can be fixed with relatively minor repairs. Highly skilled technicians are trained to spot problems by surveying a transmission and figuring out where the trouble is. Many of the common problem spots in transmissions are accessible without having to remove the transmission from the vehicle. Unfortunately, not all transmission repairs are so simple. In more serious situations, transmissions might need to be removed from the vehicle in order to repair it properly. In such cases of major transmission repair, we are often dealing with the replacement and overhaul of a transmission.

Transmission Maintenance

As a point of order, it is important to note the significance of transmission maintenance. Basic and routine transmission maintenance is your best tool to avoid major transmission repairs such as replacements and overhauls. But it can be hard to stay on top of transmission maintenance, and we all make mistakes. And sometimes you can do everything right and your transmission will still require a major repair.

Transmission Repair

As mentioned in the introduction, many transmission repairs do not require replacement and overhaul. Transmission repair is often a relatively quick process. Sometimes it requires the repair of a straightforward mechanical problem. Other times, there is a computer issue, which can be more difficult, but does not necessarily equal the seriousness of a task such as replacement and overhaul.

But not even well-trained and highly skilled technicians can repair every transmission problem without the transmission needing to be removed from the body of the vehicle. If you drive your vehicle for long enough, it will become likely that an overhaul becomes necessary at some point. While replacement and overhaul is a more involved process than many transmission repairs, it is not an automatic catastrophe by any means.

Overhaul And Replacement

When the time comes that your transmission needs an overhaul, you have two options from which to choose. The first is to remove your existing transmission and overhaul 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.

In many, indeed, probably the majority of situations, replacing your transmission with a used one is unlikely to be your best option. Used transmissions often have questionable histories that could present a whole new set of problems and issues. New transmissions, on the other hand, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts. Given this, you should err on the side of overhaul. Unless your technician presents you with a cogent and comprehensive reason as to why you should replace your transmission, you should probably opt to overhaul it.

The most commonly asked question of transmission repair is, “how much will it cost?”. Of course this is the most natural question. But there’s no one answer. Every transmission repair is different and we cannot estimate a cost without first running a diagnostic test. However, at Mister Transmission, we are always up front about our costs and will explain to you why any transmission repair will cost what it costs.

On June 30th 2025 I was having such a horrible day. My boyfriend changed my transmission oil a few days prior. When I would reverse my car everything would shut off. 10 minutes to get out of a driveway is insane. The 30th of June i called Mister Transmission and Rob picked up and said I could drop my car off and he’d look into it. Rob and the man working with him were truly amazing. From the moment I walked into the building I was greeted. He didn’t try to con me as I am a female. Rob has a pure heart of gold. When my car was there it didn’t do any of the shutting off and they did every diagnosis test. I was beyond anxious and having a bad day Rob really calmed down and lightened the mood. Thank you Rob

I would first like to say the customer service and Mister Transmission is none like I have ever experienced. I had the pleasure of speaking with Denise who was so professional, patient and indescribably kind. Not only did she take the time to detail what my car needed and how long it would take, they took the time to provide alternate cost efficient options. For those looking for transmission repairs , I promise you you will find no better!!!

Hi I had my 1966 Chevelle Malibu SS in at Mister Transmission Sarnia to have the transmission worked on last year. Mike in the back shop worked on my car (pride and joy). He did the repairs that was needed done and a few extra things done without request. The car ran like a dream when I got it back. The cost was lower then they said it would be. I'm very fussy on who works on my car. The owner (manager) was awesome to deal with. Then this week 04 July 2025 I needed a shift cable repaired as I was headed out with my car . I went to the shop and they were over loaded with work. Mike made time to get my car fixed so I could use it on the weekend. They went the extra mile to get my car fixed and again I could not complain about the cost to repair the cable. I fully recommend them and the people that work there are outstanding. A special thanks to Mike who worked on my baby(my car) thanks so much guys. They are my go to shop with my Classic car and all my vehicles.

Xavier Montenegro
I had a fantastic experience with the whole Mr. Transmission team. Jordan and Jason are fantastic at their jobs, and they are truly willing to be honest and completely transparent with you. I took my 2018 Sierra to them for some transmission work (shocker), and they were quick, and the transmission now works fantastically. There were some small hiccups, the transmission initially acted a little weird, but they were quick to correct that. I had my spark plugs and a few coils swapped over here. One of the coils they got from GM blew up and took a couple of fuses with it. They comped the tow and had it fixed quickly, and were incredibly apologetic about the whole thing. Overall, if you are looking for quality service from a tried and true team, this is the place you want to go.
