Transmission Repair & Service Collingwood, ON

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.

We took our rather aged vehicle (13 years and counting) here to be checked for transmission issues as our mechanic thought our vehicle issues might be the trannie. However, a thorough checkup, including but not limited to a drive by Mr. Transmission staff showed it is not the transmission at fault. They took it out on the road long enough to get several code readings (longer than our mechanic who could only generate one inconclusive code reading) that spell the demise of our vehicle (at 330,000 km & 13+ years, it has had a good run). They advised against putting $$ into the vehicle as they ran a few other tests that point towards a full-out failure of the engine as inevitable. Consider if you will that they did not charge us to check the vehicle and they in no way attempted to take advantage of us by trying to get us to make repairs that would be costly and fruitless. It was an absolute pleasure to deal with such honest folk. Not to diss mechanics and/or service technicians working elsewhere or any repair shops but too often these days, we have run into places where they tend to "create" issues that do not exist to further their business (or so it seems). It was refreshing to deal with good and decent folk even though the news about our vehicle was not as we had hoped. Thank you, Mr. Transmission in Owen Sound for your kindness, professionalism, empathy, and honesty. We had hoped to get a few more years out of our beastie but such is not to be and we thank you wholeheartedly for not trying to take advantage of us and in fact, for advising us against costly repairs that would not be worth the investment. We wish you every success.

Alexis Dugré
Chris was very kind and helped us out when we had an issue during our vacations in Tobermory area. He picked up the phone, took the time to listen, understand and propose solutions. He took the car in to scan it and check the transmission oil quality etc to asses the severity of a very problematic check engine code on our Promaster (dodge transmission). In the end it was best for us not to repair it there due to logistics reason and that is what he told us. Would not take a dime for the service and told us to go on our way because it was the best thing to do for us. I don't see mechanics doing that everyday I'm glad there are still good people out there. Kudos to Chris and his team
