Transmission Repair & Service Calgary, Alberta

Pinpointing the exact cause of any transmission problem takes skill, knowledge, and investigation

The evolution of transmissions has made these machines and systems increasingly complex. When transmission repairs are required, determining the cause and cure for what ails can be tricky. Why? Because transmissions have become remarkably complex and computerized and that presents both advantages and disadvantages. On one hand, transmission performance has become noticeably better in all vehicle makes and models. On the other, the increased complexity and digitization of transmission systems has made repair work a highly technical and complicated affair.


As you can imagine, there are different types of transmission repair jobs and options you can choose from depending on the nature of your vehicle’s breakdown. Understanding what those options are can help you make informed decisions when faced with a choice of transmission repairs to weigh.

A Repair for Every Type of Transmission Malfunction

Some transmission repair work is straightforward and mechanical in nature. Other times, it’s a combination of mechanical and electronic engineering that’s required to get your car back on the road. The most common types of repair work include:

  • Adjustments and in-car repairs. Most minor repairs are simple matters that are done without removing the transmission from the vehicle. If yours is a computer-controlled transmission that is not shifting properly, it is often the result of a computer sending incorrect signals due to a faulty sensor, or the transmission is not reacting to the command because of a bad connection or defective solenoid pack. If a non-computer controlled transmission is shifting too early or too late, it may require an adjustment to the throttle cable. If the vehicle has a vacuum modulator instead of a throttle cable, there is an adjustment that can be made using an adjustment screw in some designs. In vehicles with modulators, however, it is important to ensure there are no vacuum leaks and that the engine is running at peak efficiency.
  • Reseal jobs. A transmission is re-sealed to repair external transmission fluid leaks. If you see spots of red oil on the ground under the car, your transmission may need a re-seal job. To check a transmission for leaks, a technician will put the vehicle on a lift and examine the unit for signs of oil leaks. If a leak is spotted at any of the external seals or gaskets and the transmission otherwise performs well, the technician will most likely recommend that the transmission be re-sealed. Most of the external seals can be replaced while the transmission is still in the car but, if the front seal must be replaced, the transmission must first be removed from the vehicle to gain access to it.
  • Replacing accessible parts. There are a number of parts that are accessible without requiring the removal of the complete transmission. 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.
  • Complete overhauls. Also known as “rebuilding a transmission”, a complete overhaul involves the removal and disassembly of the transmission in its entirety. Every part is inspected for wear and damage, then 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 remanufactured 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.

Replacing or Overhauling a Transmission

When a transmission requires an overhaul, there are two options that you may have. 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 remanufactured.

A word to the wise: replacing your transmission with a used one may not be your best option. Used transmissions often have questionable histories that could create a whole new set of challenges. New transmissions, meanwhile, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts.

The cost of the repair is always top-of-mind and understandably so. Transmission repairs are usually unexpected (and unwelcome). The cost varies depending on the outcome of our diagnostic testing, and we will help you to understand the various factors that come into play. We also offer our customers flexible payment options.

Whichever route you choose, you can trust our transmission experts to get you and your car back on the road.

I have a 2016 f150 with the 6R80 and for a little while I had almost every symptom of a bad torque converter expecting to need a full rebuild, I called in a asked for a worst case scenario qoute and was asked to bring it in, I was expecting a $4-7k rebuild I was 90% sure it was the torque converter, with a quick scan and diagnostic it was found the output speed sensor had gone and Chris without looking at a book or a screen 1300$ was the qoute and 1250$ was the final price these guys know what they are doing but the most appreciated thing you guys did for me was rush the repair knowing I had no way to get home to wait for the repair to finish they allowed me to wait in the shop and offered me coffee I really appreciate you guys. thank you for being a HONEST shop you could've just said oh yeah needs a torque converter and i would've believed you, but you didn't so thank you I will be recommending you to anyone I come across in need of you're amazing services!

Garon Baxter
After finishing a 12 hour shift shovelling snow on Christmas Eve, our F150s transmission kicked the bucket on the way home. After postponing all of our Christmas plans and limping the truck to two shops in my neighbourhood and being told that our only option was replacing it with a used transmission, a family member told us he took his Mustang in to this exact location and had it rebuilt by Kris and the crew and the results could not have been better. So we called, and immediately knew that we would be in good hands here. They correctly identified the problem before they even popped the hood, the final cost was a hair under the quoted price and finished a few days ahead of schedule, they brought out a box of all the parts they pulled out and walked us through the process, offer free checkups afterwards, and on top of all this they are confident enough in the work to offer a 2 year warranty - something no other shop would do for rebuilds. You will not find a transmission repair shop with more professional service nor one that will offer you more peace of mind. By far the best experience with a mechanic we have ever had, and I cannot recommend them enough.

Lori Moore
The mechanics looked over my sons truck and ran diagnostics on my sons truck for no cost; then they took the time to give us numerous suggestions to stop the code being triggered on the computer. Excellent advice and saved us A LOT of issues, thus saving us money. My son needed to tweak a few things and keep moisture out to prevent a “big thing” from happening.. there’s more to it but the point is they went out of their way to explain and give helpful suggestions. Female staff member goes above and beyond for customer service, warm smile and welcoming demeanour and full of great information. Very helpful, informative, friendly staff .. again the services they shared were all free of charge just to help my son out. Above and beyond expectations!
