Transmission Repair & Service Pickering, 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.

Mackenzie Spencer
Top notch service at this location. I had a very specific situation with the transmission in my car, they were comfortable with me bringing my own part & had it installed for a very fair price. Other locations gave me insane quotes, I was very happy with my experience with Chris. My silly little Honda CR-Z is good as new.

J. S.
serviced my ol' domestic x-over. made me read up on the matter. got to appreciate the complexity of hydraulics & kinetics involved in the transmission system. these gents parent-&-son can listen, relate/empathize, perform & deliver. doing the replacement itself is extremely tedious. a personalized approach they both do. Ken, an ex-aviator hobbyist, & his son Chris, a hands-on specialist, are like 2 gears in synchrony (some comments are a bit mean). read the way they reply to the negatives - tells me their character. professionals. Merci!

Chris Elliston
I recently brought my car to Mr. Transmission to have a wheel bearing and axle shaft replaced, and I couldn’t be happier with the service. The price was very fair, and the work was done professionally and efficiently.What really stood out was the customer service — they even drove me home while my car was being worked on, which made the whole experience much more convenient. It’s not easy to find a mechanic you can truly trust, but these guys are honest, reliable, and clearly care about their customers.I would highly recommend bringing your vehicle here if you’re looking for a trustworthy and dependable mechanic shop.

Ann O'Regan
I had a problem with my 2012 Honda Civic trani with 625km. I took it to Honda service for a diagnosis and it was confirmed to be the transmission.But repairs and new/used parts would be way too costly. For about 6 months knowing it could of been an engine mount issue due to strong vibration, a bit of gear slipping and some jerking while increasing speed...so I brought my car to Mr. Transmission in Pickering and was welcomed by a such a nice gentleman Chris, the owner Ken's son when I told him my issue. Right away we went for a test drive on the highway returned and did confirm and explained in detailed as a second opinion that I needed a new used trani and definitely a torq converter...he located a trani for me at a very great price with low kms and I chose to get the work done with him. A date was set when the trani was delivered. I dropped off my vehicle 2 days later at 9am. I rented a car at Enterprise Car Rental that morning as they were in the same automotive plaza. To my surprise, by 3pm, I received a call from Chris that the work for the transmission being replaced was complete in a very timely manner. I was ecstatic as I didn't expect to be done till the next day. I returned the rental and picked up my car. It's been running excellent like a brand new car as I do a lot of mileage weekly on my vehicle. I could not have been more happy about the whole experience with Mr.Transmission in Pickering with Chris. His customer hospitality, honesty, caring and very reasonable pricing made it all worth it explaining every detail what had to be done delivered professionalism and expertise at its best. I highly absolutely recommend this place to cater to all your transmission needs from a truly satisfied customer!!!!

Amy B
If you need transmission work on your vehicle, this is the place to go to. I brought my son's car here for transmission issue which was diagnosed by at least three other places for a lot more and for the worst of you would expected. When I tried this last place it turned out the best place. Talked to Chris he was very knowledgeable got my car done the same day at a minimal cost. I was back a year after with my daughter's car with a different transmission issue and also got done at a very reasonable cost and honest diagnose. This transmission place don't just fix transmission problems but does other repairs at a very reasonable price, honest, and very reliable. I have referred others here and very happy with services as well. Thanks Chris and Ken for taking care of my family car issues. Please keep up the good work as it is hard to find business that runs with ethics and honesty in this tough economy.

Ken was fantastic to deal with, he went above and beyond to help me out with my Volvo. I will definitely be a returning client if anything like this happens again in the future. I couldn’t be happier with the work that they did.
