Transmission Repair & Service Brampton, 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.

Dave Lundy
Brian was very professional and patiently answered all my questions so I could understand them. Our 2008 Mazda CX-9 now has a bit more life left in it, so that will buy us some time to make a replacement without being pressured. Besides, we like the Mazda quite a bit; it is fun to drive. If I get a late-model car in the future, I will remember from now on to change the transmission oil every 2 years. One of the useful tips Brian shared with me.

Brian Pearson
Automotive service, particularly for older model vehicles, can be hit or miss, and unfortunately mostly miss. At least this has been my personal experience in the Brampton area. Or I should say, that had been my experience until last week. The service I received from Stafford (Brampton - Mister Transmission) was a prime example of true customer focused automotive service. Stafford went above and beyond to ensure our issue was resolved. Stafford worked within their busy schedule to look at our vehicle, identify the problem and then, due to part shortages, took the time and effort to recondition the failing part and get us safely back on the road. Stafford - Thank you!

Kulwinder Dhillon
Stafford was extremely professional from start to finish and made me feel comfortable that I was in good hands. Took my 2016 Nissan Sentra to multiple places and either got outrageous quotes or incorrect diagnosis. Stafford and the team were very knowledgeable about exactly what the issues were and were upfront about it all with no shadiness. They also got the car towed from Nissan to their shop, free of charge. The diagnostic was free of charge as well. Both fees were waived because I got the work done by them. Now my car runs very smooth, better than it has in years. 10/10 would recommend these guys!

Second time we have taken one of our Ford vehicles to Mister Transmission for repair as the dealership either misdiagnosed or couldn’t do it all together. Luke and Stafford were great and they have a complete run down on everything that was needed or not needed.

Sam Gribley
I just picked up my vehicle at 28 Kennedy Rd South in Brampton. I was very satisfied with the service and staff there. My transmission broke down and I dropped it off to Tony the next morning. After they diagnosed it he called me with a time frame and estimate. A few days later I talked with Stafford who told me there was a problem finding a part. But they would do their best to complete the work on time. Sure enough, first thing this morning I got a call saying my car was ready to be picked up. Both Tony and Stafford are polite and professional. Very happy guys! Thank you.
