Truck transmission

At our truck transmission repair shop in Saint-Eustache, LOURDMEC SERVICES MÉCANIQUES serves a large clientele from Laval and surrounding cities.

Whether you drive a single semi truck or manage an entire fleet, you know that when the transmission starts acting up, you can’t wait.

The same goes for excavators, tractors, or any type of heavy machinery: when a transmission fails, it means lost time and lost money.

At LOURDMEC, we handle all types of semi truck and heavy machinery transmissions (manual, automatic, hydrostatic, or continuously variable) and all major brands (Allison Transmission, Eaton/Fuller, ZF Friedrichshafen, Meritor, Spicer, Volvo, Mack mDRIVE, DT12, Freightliner/Detroit Diesel, Volvo I-Shift, and more).

We also perform replacements (with new transmissions) as well as complete transmission rebuilds for semi trucks and heavy machinery, using manufacturer-recommended parts.

Remember that regular maintenance of your semi truck ensures your transmission will remain in excellent condition for the long term.

Warning signs to look out for

  • If you’ve noticed vibrations, jerking, or repeated clunking noises when shifting gears, or if you are having difficulty changing gears, it’s very likely your transmission needs repair.

  • Likewise, if you feel a loss of power when engaging the clutch, notice signs of overheating, or see that your truck is consuming fuel too quickly, don’t ignore these symptoms. The sooner we intervene, the simpler (and less expensive) the repair will be.

The importance of keeping your truck transmission in good condition

  • The transmission transfers the engine’s power to the truck’s wheels. This system allows smooth and safe gear shifting while optimizing engine performance.

  • We know that a transmission failure can cause costly breakdowns and serious project management issues.

  • Don’t wait to contact us: the problem can eventually affect your engine and even compromise driver safety on the road.

Transmission parts repair and replacement

We repair or replace manual and automatic gearboxes, as well as electronic control modules (TCM).

We also service drive shafts, universal joints, and hydraulic and pneumatic components. Only original (OEM) or equivalent-quality parts are used.

When a transmission is severely damaged, we offer complete overhauls: disassembly, cleaning of every part, replacement of all worn or broken components (including clutch brakes), followed by testing on our bench.

Once the rebuild is complete, your transmission will operate efficiently again, just like new.
