How Easily Can Transmissions be Repaired?

By Mister Transmission

If the tire on your wheel becomes punctured, you can replace it. If your battery runs out of power, you can replace it. If one of your headlights burns out, you can replace it. But if your transmission breaks…then what?

Whether or not you are able to replace any of the above items yourself, you probably have a pretty good idea of what’s involved. And while any of these breakages would be unwelcome obstacles in your day, they’re all remedied relatively easily. But with transmissions? While it is possible to completely replace and overhaul a transmission, it is not a simple nor an easy process. But are all transmission repairs so complex?

Transmissions

The transmission is one of the most complicated, intricate, and sophisticated components of your automobile. This is true for a number of reasons. For starters, the transmission is not just one thing but rather a collection of parts working in synchronicity with one another to make your vehicle operate. And with multiple components come multiple points of potential problems, all of which require different types of repair, which themselves vary in complexity and difficulty. If your right tail light doesn’t work, you know what to replace. If your transmission is acting up, it’s not so simple.

Furthermore, transmissions have become increasingly complex over the years. A lot of this is due to the increased computerization of transmissions. This process has made transmissions more efficient and more in-touch with the vehicle. However, it has also increased the number of things that can go wrong. And it’s not like this is something you can solve by sliding under the car in your garage with a monkey wrench. You’ll need special computer technology for these repairs.

Transmission repair

The truth is that many transmission repairs are minor affairs that can be done without removing the transmission from the body of the vehicle. This is more or less the threshold in determining the ease of a transmission repair. Though perhaps “ease” is not the right word. If a transmission can be repaired without being removed from the body of the vehicle, then an experienced and skilled technician with the right equipment can do the repair without too much trouble.

For computer controlled transmissions, the first step in transmission repair is usually to connect computerized diagnostic equipment with the vehicle’s onboard computer. Running these diagnostics will often pinpoint the problem, whether is a faulty sensor or defective solenoid pack. If the problem lies in an accessible part –that is, a part that can be accessed with the transmission remaining in the body of the vehicle– then the repair can be done relatively swiftly by replacing said part.

Get in touch

Sometimes transmissions incur problems that require much more involved and complicated repairs. A reseal job can be easy enough if there is a clear, solitary leak. But total reseal jobs are quite a bit trickier. And we haven’t even mentioned repairs that require complete overhauls, in which technicians remove the transmission, disassemble it, and look for the problem. In such a case, the transmission repair is far from easy.

All of this is to say that transmission repairs vary greatly depending on what is required. If you have questions about a repair you think your transmission may need, please contact us today.

This St. Margaret location was awesome. They found my rear engine leak in next to no time at all. And took care of a few other random repairs too. Even though they're are a transmission shop, they went above and beyond for me and my repairs which im so appreciative of. I will be recommending them to anyone who asks. No wonder they've been in business so long. Great work!

Blair and his team at this location seem to be the go-to for known and unknown transmission types and were recommended by another mechanic shop. For example, I needed to replace a transmission on a 2003 Right-Hand-Drive (RHD) Hybrid Toyota Estima I imported and they were able to swap it out. I appreciated that someone in the city was willing to get creative and not turn me away because it wasn't part of a pricing template.During a more recent visit, I needed a diagnostic for a Used Nissan Pathfinder I had purchased and requested a CVT fluid change. The diagnostic returned a faulty Mass Air Flow sensor. The front desk (Darren) went with an OEM sensor ($600) versus one of the $200 sensors you find on Amazon and his rationale for doing so seemed sound as many of the reviews showed that oversea-sourced sensors from Amazon fail within a year.Perhaps I'm of a more curious nature than most, and I have plenty of questions about the work being performed, what's being used, and the condition of the fluids being removed. I appreciate when shops help me understand their rationale. Darren is a pleasant-enough fellow, however, I did not feel on my last visit that we were in sync when I was seeking information on the condition of my transmission and fluids. At one point I was told that, "Curiosity killed the cat," which I found an odd response to a straightforward question. I'll chalk it up as a misunderstanding. My advice to this location is that a little information goes a long way to reassuring the customer. If Darren had been a bit more curious about the work being performed, I would have felt in a better position to say it was money well spent. My vehicle doesn't drive or perform any different since having the sensor and CVT fluid changed, so in my case, I would have welcomed a confident accounting of the condition of the fluids and work. Dare I suggest photos as some of the other shops are now doing. I'm glad we have Blair and his mechanics here in the city doing the work they do. My suggestion for improvement is that they modernize some of their process and systems (eg. photos on file) so that customers like myself can feel reassured throughout the interaction and beyond.

Great service, very transparent pricing. They kept me in the loop through the entire process with updates, got my transmission rebuilt in about a week. Warranty was the big reason I went with them.
