Transmission Repair & Service Burlington, 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.

Sterling Jetha
Brought my car in to get a new clutch. Service was very quick and professional, answered all my questions, and gave a much better price than the dealership. Car is driving very well, like new again. Alistair and Bryan were very accommodating and informative.

Alexander Sousa
Customer service was exceptional, especially the free diagnosis. Alistair was excellent and very knowledgeable at explaining my transmission issue in detail and providing a breakdown of the problem for my vehicle in specific. Transmissions are an unfortunate expensive repair, but I was pleased with the results and my vehicle’s improved performance. My vehicle ended up being a two day fix. I highly recommend visiting Mister Transmission in Burlington instead of taking your vehicle to a dealership that will double the cost of a minor repair, just to have thicker pocket change.

Rick Owens
Although no one wants costly transmission problems, I was very pleased with my dealings with Mr Transmission. From the moment I dropped the car off until it was ready for pickup, I was kept informed on the diagnosis and repair status. I felt confident that my vehicles issues were being addressed properly. Having a full year warranty on the work completed also provides peace of mind. If your transmission is acting up I would definitely recommend the team at Burlington Mr Transmission.

Fred Zumer
I spoke with Alistair on Friday, and he had my vehicle in already for Monday morning. He took his time to explain exactly what needed to be done in terms of diagnosing the vehicle with a scanner, and from this, determine the issues I was having. Once diagnosed, the repairs began. The vehicle runs beautiful now with a complete overhauled transmission. I am very happy with the experience.

These guys are the best. They were incredibly communicative, keeping me updated on every step. They dealt with my warranty provider for me, making sure I had the most coverage possible. On top of being generally good people, their work is also top notch. I highly recommend!

Matt Rundle
Great place! Alistair looked at my car the day I called and had it back to me fast. Turned out only to be a faulty sensor so the repair was cheap as well. Didn’t try to do any unnecessary work. I would completely trust them in the future.

Raffi
I called Mister Transmission on Wednesday and spoke to Brian, and he was able to see me for an appointment within one day! Had a very pleasant conversation with him over the phone, and he basically walked me through quite a bit of information about my car/transmission ect. Brian took my car in for their free roadtest/computer diagnostic and I received a call back very quick, about an hour or so! Preparing myself for some bad, I was shocked to hear the prelim diagnosis! Brain recommended that I do some prelim maintenance with regards to my fuel injectors which may be causing some shudder in my car. As many people know, anytime you take something for an inspection or service you expect them to find something to charge you for. Not here for my case. Brian seems like an honest man and confirmed my first impressions on him over the phone. I am very satisfied with my service so far and would recommend Mister Transmission to anyone I know and hope the owners and management know they are lucky to have Brian there for them!
