Transmission Overhaul — When Your Transmission Needs More Than a Quick Fix

When your vehicle starts slipping gears, shuddering on acceleration, or refusing to shift smoothly, the problem often runs deeper than a fluid change or a minor adjustment can solve. A transmission overhaul addresses the root cause — worn internal components, degraded clutch packs, failed solenoids, or damaged gear sets — before those issues leave you stranded or facing a full transmission replacement. Ignoring the early warning signs doesn’t make them disappear; it accelerates the damage and drives up the eventual repair cost. At Mister Transmission Peterborough, our specialists have been performing transmission overhauls across Canada since 1963, with the expertise and equipment to do the job right.

What Is a Transmission Overhaul?

A transmission overhaul — also called a transmission rebuild — involves removing the transmission from the vehicle, completely disassembling it, inspecting every component, replacing all worn or damaged parts, and reassembling it to manufacturer specifications. It is a more comprehensive solution than a basic repair and a more cost-effective alternative to full transmission replacement when the core housing and major components are still structurally sound.

A transmission overhaul typically includes:

  • Full disassembly and cleaning of all internal components
  • Replacement of clutch packs, bands, seals, and gaskets
  • Inspection and replacement of solenoids, sensors, and electronic components as needed
  • Torque converter inspection and service
  • Reassembly to OEM specifications
  • A complete transmission fluid service with the correct fluid type for your vehicle

Common Signs You May Need a Transmission Overhaul

Not every transmission problem requires a full overhaul, but certain symptoms strongly suggest the internal components have worn beyond the point of simple repair. Watch for:

  • Gear slipping — The transmission shifts into a gear but then slips out unexpectedly while driving.
  • Rough or delayed shifting — Noticeable hesitation, jerking, or clunking when changing gears.
  • Shuddering or vibration — Felt most often during acceleration or at highway speeds.
  • Burnt transmission fluid — Dark, opaque fluid with a burnt smell signals serious internal wear.
  • Check engine or transmission warning light — Often triggered by solenoid or sensor failures detected during transmission diagnostics.
  • Complete loss of drive — The vehicle moves in neutral or fails to engage any gear at all.

If you’re experiencing more than one of these symptoms simultaneously, a transmission rebuild service is likely more economical than patching individual components one by one.

Frequently Asked Questions

  • How long does a transmission overhaul take? +

    The time required for a transmission overhaul depends on the vehicle make and model and the extent of internal wear discovered during disassembly. Most overhauls take between three and five business days. Your Mister Transmission Peterborough technician will provide a realistic timeline after completing the initial diagnostic inspection, so you can plan accordingly.

  • How much does a transmission overhaul cost? +

    Transmission overhaul costs vary based on transmission type (automatic, manual, or CVT), the number of components requiring replacement, and the vehicle's specific requirements. Because every unit is different, Mister Transmission Peterborough provides a written estimate after inspection — not a vague range over the phone. This ensures you understand exactly what the work involves and why before any repairs begin.

  • Is a transmission overhaul worth it, or should I just replace the transmission? +

    In many cases, a transmission overhaul is the more economical and practical choice. If the transmission housing and major structural components are intact, rebuilding the unit to OEM specifications restores full performance at a lower cost than sourcing and installing a replacement. Our technicians will give you an honest comparison of both options, including the associated costs and warranty coverage, so you can make the decision that makes the most sense for your vehicle and budget.

I wish I could put...
Heather Hunter
I wish I could put 10/10 stars. This place is excellent and I highly recommend them. I was having issues with my vehicle lagging on hills and on start off. I believed it may have been an exhaust issue which could have been costly. Joe, the front manager, is an awesome individual. Friendly and informative. One of his workers took the vehicle for a drive and came back with a diagnosis. The air filter box had not been closed properly, affecting the car's ability to receive enough air. It was fixed free of charge. Wow!! Any other mechanic would have charged me for the correction of the box. To future customers. You will not be disappointed. Keep up the awesome customer service Mister Transmission!!!

Arlene Peever
My vehicle totally shut down on Hwy 115 and the only display message was service transmission so I had it towed to Mr Transmission in Peterborough. Turns out that it was not the transmission after being on the diagnostic machine for hours but electrical. Joe then had it towed to the GMC dealership in Lindsay where they determined it to be the fuse block and electrical module. Fixed and then brought back to Peterborough. Definitely went above and beyond for me. Would highly recommend. Sincerely, Arlene

Randy G
I’ve been to Mister Transmission in Peterborough twice. The first time I had my trucks transmission, torque converter and differential fluids changed. The second time I was looking for a transmission part for an old vehicle. Both times the service was excellent and the staff were very knowledgeable and friendly. The price for the fluid change was great, they refused to take anything for the transmission part. Thank you
