Truck Transmission Repair in Mississauga
A transmission problem can leave a loaded truck stuck, so catching it early matters. Ontario Truck Repair services and repairs manual and automatic transmissions, drivelines and differentials for commercial trucks at our Mississauga facility.
What we repair and service
For manual transmissions we handle clutch replacement and adjustment, gearbox service and rebuilds, synchronizer repair, shift linkage adjustment and transmission mount replacement. On automatics we offer fluid service and flushes, control module repair or replacement, torque converter service, shift solenoid replacement and complete transmission rebuilds. Behind the gearbox we service the driveline, including driveshaft service and balancing, U-joint replacement, carrier bearings, yokes and CV joints, as well as differentials, including gear and bearing replacement, axle seal repair, differential fluid changes and limited slip service.
Signs your truck may need transmission or driveline work
- Gears slipping, grinding or shifting hard
- A clutch that slips, drags or feels different underfoot
- Fluid leaks under the truck or a burnt smell
- Vibration or clunking from the driveshaft or U-joints
- Whining or noise from the rear axle or differential
Why it pays to fix it early
Transmission damage often starts small: low or worn fluid, a tired clutch or a failing U-joint. Driving on a slipping clutch or a noisy driveline can damage gears, bearings and the driveshaft, turning a modest repair into a full rebuild. Regular fluid service and quick attention to new noises are some of the cheapest protection you can buy.
Why Mississauga fleets choose Ontario Truck Repair
Our transmission and driveline work is done by certified technicians who receive regular training. We fit OEM or premium aftermarket parts backed by strong warranties (the warranty depends on the repair and parts used), and each repair is checked more than once before it leaves the shop. Our goal is simple: reliable repairs that minimize downtime and keep your fleet running safely and efficiently.
