Expert Transmission Repair & Service in Leslieville, ON

Pinpointing the exact cause of any transmission repair issue in Leslieville, ON requires skill, knowledge, and thorough investigation. The evolution of transmissions has made these systems increasingly complex. When transmission repairs are needed, determining the cause and solution can be tricky. Why? Because transmissions have become remarkably complex and computerized, which presents both advantages and challenges. On one hand, transmission performance has noticeably improved across all vehicle makes and models. On the other hand, the increased complexity and digitization of transmission systems has made transmission repair a highly technical and complicated process in Leslieville, ON.

Types of Transmission Repair Jobs in Leslieville, ON

As you can imagine, there are different types of transmission repair jobs and options available depending on the nature of your vehicle’s breakdown. Understanding these options can help you make informed decisions when choosing the right transmission repair in Leslieville, ON.

A Repair for Every Type of Transmission Malfunction

Some transmission repair work is straightforward and mechanical in nature. Other times, a combination of mechanical and electronic engineering is required to get your car back on the road. The most common types of transmission repairs include:

1. Adjustments and In-Car Repairs

  • Most minor transmission repairs are simple matters that are done without removing the transmission from the vehicle.
  • If your computer-controlled transmission isn’t shifting properly, it could be due to a faulty sensor 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. In some designs, a vacuum modulator adjustment can be made using an adjustment screw.
  • In Leslieville, ON, our technicians ensure that there are no vacuum leaks and that your engine is operating at peak efficiency.

2. Reseal Jobs

  • Transmission reseals are performed to fix external fluid leaks. If you see spots of red oil under your car, your transmission may need a reseal.
  • In Leslieville, ON, technicians will lift the vehicle and examine the transmission unit for signs of oil leaks. If a leak is found, they will recommend resealing external seals or gaskets.

3. Replacing Accessible Parts

  • There are certain parts that can be replaced without removing the entire transmission.
  • The parts accessible for repair vary depending on the transmission, and our transmission repair experts in Leslieville, ON will inspect these areas to ensure proper operation.

4. Complete Overhauls (Rebuilding a Transmission)

  • A complete transmission overhaul involves removing and disassembling the transmission. Every part is inspected for wear and damage, then cleaned or replaced as needed.
  • Friction components, such as bands and clutches, are replaced, along with seals and gaskets.
  • The torque converter is often replaced with a remanufactured one, and technical service bulletins are checked to address any known manufacturer issues.

Replacing or Overhauling a Transmission

When your transmission requires an overhaul, you have two main options:

  • Rebuild your transmission: Remove your existing transmission, overhaul it, and reinstall it in your vehicle.
  • Replace with a rebuilt transmission: Replace your existing unit with another rebuilt or remanufactured transmission.

A word of caution: Replacing your transmission with a used one may not be the best option. Used transmissions often have unclear histories that could lead to further issues down the road. New transmissions, marketed as new, are typically rebuilt transmissions with new parts.

Tafadzwa Makumbiro
Had a 2019 Mitsubishi eclipse cross transmission redone by the mister transmission down by o’conner drive and it was a rebuild and I must say they did a fantastic job. Mitsubishi dealer tried to quote me 10k and buy a new car after my transmission went but spoke to the owner and they did the job for 6.7k with taxes parts and labor and it was a much better deal than just throwing away a perfectly usable car. The rebuilt was done well my car moves great never felt such great driving experience. Car feels very strong now compared to when I bought it used. Already put about 2k kms on the car but since my vehicle is a high milage business purpose car the rebuild fixed my car so good I would highly recommend these guys. Still got warranty on the vehicle for the coverage of the repair but hands down great place to get your transmission rebuilt. If you ever need a transmission replacement or repair get a quote from these guys before getting rid of good performing cars for new car payments. Better a few thousand dollars of repairs than years of debt payments.
