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.

  • The repair was priced fairly and the hop accommodated our special needs with our motorhome. Repair was done on time, however, a bolt was forgotten to be tightened and speedometer cable broke after 2km.

  • I received a quick diagnosis after having my car towed to the repair shop. The technicians were conscientious about doing a good job and not rushing to get it done quickly. They also fixed another problem I was unaware. They were knowledgeable and explained things to me over the phone and in person when I picked up my car.

  • Kris Carlson was pleasant to talk to and explained the issue with my transmission well. He also proposed different scenarios; best and worst case. Timing of repair/overhaul was excellent which was done in only two and a half days. As the final repair cost was quite significant, Kris gave a discount which was very much appreciated. Kris also went over the terms of the warranty and offered further support (to come back) should any unexpected issues arise. I hope I don't have to come back but if I do, I know I will be taken care of. I highly recommend Mister Transmission in Calgary.

  • I had replace the shift solenoid module myself after receiving ODBII code, but shortly afterwards received P0876 & P0740 codes which indicated worst problems yet transmission was working fine. I took it to Mr.T. Kris took it for test run and found it working just beautifully but told me drive it and get it to go limp mode and come back. I did. Kris then found several codes recorded. We schedule repairs. Kris rebuilt transmission, more codes showed up , he fixed those with new valve body. I pick suv up and before I even got back home it was acting worst than when I brought it first in. So back to Mr.T on Monday where Kris spend several days swapping out components to find problem. It was the shift solenoid I put in; defective. Kris put new OEM in and problem solved. Kris only charge me for that shift module; only fair since I could return the other for refund. Kris said the 1% of his jobs cause him 99% of his problems....but changed his mind to say that this "One Job" caused him that. It's hard to second guess a new part, and I'm sure he lost money on this job, but he never change his demeanour during the whole time, and he was still happy I brought my work to him; and he was happy he solve my problem. If you want a review this is it; "Mister. Transmission is even willing to loose money if need-be to fix your transmission to their satisfaction". And for the customer, it's good to know that Mister. Transmission is not going to intentionally give you a low-ball estimate and try to milked you dry later with extras. Their estimate is based on their road test and experience and any other agreements you make with them and they're willing to work with that. Dean Moss, Calgary

  • Kris at the Calgary branch was extremely friendly and treated us not as dummies as I found with other auto centres. He took the time to explain to us what they had done at mister transmission to the car. Hopefully now it will keep us on the road for a long time.
