Transmission Repair & Service Peterborough, Ontario

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.

Patrick Ritchie
I’m from Ohio and was up visiting family for the week. Monday morning at 4:30 AM 15 miles from their house my transmission went out in my 2013 F150. I called Bells garage in Bridgenorth they towed it and said it needed to go to Mister Transmission in Peterbourgh. As the holiday weekend approached I didn’t know how I was going to get back to the States. Cam called me and said he couldn’t promise but they would try to have it done by Friday. He got it done and I couldn’t be happier. Thanks for all your help you guys are the best

I had a great experience...
Trev Cushing
I had a great experience at Mr. transmission in Peterborough. Upon first contact of the shop Cam was able to quickly make an appointment for my truck to be dropped off and road tested. I was able to drop my truck off about 3 days after fist contact and it was road tested that day. I was contacted by cam and was told my transmission had internal issues and would have to come apart. In that same phone call cam was very clear and let me know that it could take a couple of weeks until my transmission would be removed due to there busy schedule. I was very happy this happened because it allowed me to have reasonable expectations for how busy they were at the time, and how long it might take to get the job started and completed. I experience very clear communication with Cam and the shop through out the process. Once they were able to pull the transmission out and diagnose the issues they built a quote and contacted me asap. They Give me some options depending on how I was going to use my truck in the process of rebuilding the transmission. Once I approved the quote it only took the shop 1-2 days to complete the work and finish the job. So far I’m extremely happy with how my truck is now running feel that my issues have been fixed. I feel throughout the entire process everything was communicated very clear to me and they took the time to explain anything I had questions about. The process may have taken longer than I had originally thought however I am very happy that I chose Mr. transmission. I feel the wait was worth it due to the Quality of work they provided. Hopefully I don’t have any issues in the future but if I do I’ll definitely be coming back to mr. transmission in Peterborough. Keep up the great work!!!! -Trevor C.

Terry and his team assessed my older Lexus and took a stepped approach to fixing it, with the least intrusive and least expensive step first. As a result, it works great and I appreciate that they didn't do any more work than was needed.
