Transmission Repair & Service Mississauga, 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.

Stefan Pisocky
I had a shifting problem and a clutch problem in my manual Elantra. I had gone to two other Mr. Transmission locations and to a Hyundai dealership. All of them misdiagnosed the problem as a transmission problem. I told Mike what parts in the transmission they said needed to be fixed. If Mike were dishonest, he could have used that information to replace parts needlessly, and I would never have known. But he did not. It is rare to find honest hard working mechanical investigators like Mike Arbeau.

Merrilee Stoll
Excellent experience and treated with respect!! Can't ask for anything better. My car was leaking fluids, and the engine was making weird noises, all-in-all I thought it was transmission related. Ultimately, it was radiator hoses and a relatively quick fix to get me on my way. During the entire visit, I was not 'talked' down to, and I experienced the courtesy of being told my guess made sense, given the location and look of the leak. I was also given tips in case the hose replacement was not the only issue.

An unexpected, great experience. My regular mechanic was unable to take my car, and with an axle noise increasing in volume, and a long trip coming in just a few days, I was searching for a reliable place to take my car. I noted that this Mister Transmission is the current incarnation and location for a garage (‘Precision Transmission’) previously recommended by the Automobile Protection Association, so I decided to give them a call. Since an axle is part of the ‘drive train’ they agreed to take the issue on. I brought it in and they went for a 20 minute test drive to hear the noise. (The drive was long because of heavy traffic). Then they switched up some scheduling to make time on their hoist in order to run the car while observing the rotating wheels and drive train. The problem became obvious: a worn left axle — which had been changed only 6 months earlier at my usual garage. Clearly the part has been poor quality or defective. Mister Transmission assured me that I was safe in the short term to continue driving with it, AND they encouraged me to take the back to the mechanic who had done the work originally, for follow up. They would gladly have done the job, but felt it might be in my best interest to have the original mechanic follow up because of the early part failure. I asked them to please charge me for the time and expertise they had provided, but they would not, though I was persistent. I would gladly recommend this business to anyone in need of transmission or drive train service. They are trustworthy and kind, and I am grateful for their help.

Chris Brooks
The staff at this location were very helpful. I was taken care of efficiently and with great respect. They recognized that the nature of this type of repair is very stressful for the client and did everything they could to help ease the stress. I would recommend this location to anyone who wants a no nonsense approach to their transmission repair. Very fair price and they even drove me home when I dropped the vehicle off.
