3 Major And 3 Minor Transmission Repairs

Transmission repairs are not all equal. There are minor and there are major transmission repairs. Here, we will go over three of each.

Minor Transmission Repair #1 – A Computer Scan

It’s 2021, so of course your vehicle has a computer in it. Unless you’re driving something very old, your vehicle probably has an onboard computer, and it can play a key role in diagnosing transmission problems. While it’s not particularly difficult to interface with your vehicle’s onboard computer, it does require the right technology and knowhow; this isn’t something even the handiest of car enthusiasts can do in their home garage. But at Mister Transmission, we can connect to your vehicle’s computer to find problem areas, such as faulty sensors or defective solenoid packs.

Major Transmission Repair #1 – Finding The Right Part To Replace

The computer doesn’t always give us a clear treasure map leading us to problem parts. That’s when things can get tricky. Having to hunt around to try to find what’s going wrong in a transmission can be a lengthy and aggravating process. It might even require the removal of the transmission from the chassis, and any time that becomes necessary, it’s a major transmission repair.

Minor Transmission Repair #2 – A Partial Reseal Job

Transmission fluid is the lifeblood of automatic (and some manual) transmissions. You don’t want to be leaking it. Thankfully, most leaks can be isolated and resealed without too much trouble, for example an axel seal or pan gasket.

Major Transmission Repair #2 – A Complete Reseal Job

There are times, however, when a complete reseal is necessary, because of multiple leaks, a coming apart of a transmission, or a difficult to locate leak. A complete reseal is, as you would expect, more involved than a partial one.

Minor Transmission Repair #3 – Automatic Transmission Fluid Change

Because transmission fluid is so important, it’s vital to keep it in good condition. This means checking it regularly (ideally once a month) and topping it up when necessary. We can do this for you at Mister Transmission easily. A little more involved is changing the transmission fluid, where we let the current fluid drain out, examine it for particulate matter, and replace it with a new filter.

Major Transmission Repair #3 – A Transmission Overhaul

Sometimes, because of an inability to find the problem part(s) or because so much of the transmission is damaged, it needs to be replaced. You can replace a transmission. which is a bit less labour intensive, but we generally advise against it. The refurbished replacement often has unknown provenance which could be problematic. Instead, every part should be examined and cleaned or replaced.

Brought in my 2014 F-150 with a transmission concern. Kris and the team were upfront about what was needed and what wasn't, and completed the repair cleanly and professionally. After 30+ days of varied driving including cold starts and extended sits, pulling trailer, city driving, the truck is shifting perfectly. Honest shop, fair price, no unnecessary upsells. Highly recommend Kris and the team at Mister Transmission. There is a reason this shop is so busy!

We broke down in the Sault as we were traveling through -We were stranded! Mr. Transmission moved some things around to get us in. He ended up staying late on a Friday and coming in on a saturday so we would be able to head home. Great service, excellent communication and overall great place.

3 tries to get an appointment (Automated booking cannot be trusted, the next booking was rescheduled due to parts not in on time). I went to my dealership for another matter and asked about parts for MrT. They arrived the week before but nothing was ordered specifically for me. When I called MrT, Sara said she meant to call last week but got busy. She didn’t call me the next business day either so I recommend you call them to keep on top of things:) Other than that, service was good, fluid and filter changed, pan inspected. I dropped off my vehicle night before and it was ready after lunch the next day.
