Authorized Allison Transmission Dealer

We distribute a complete line of Allison transmissions, from hydraulic to electronic. We can overhaul your old transmission or supply you with a factory Allison re-tran. Our mechanics can evaluate your current needs and provide a solution that will best suit your specific situation.

Complete Engine Overhaul

A common mistake made by many drivers is purchasing a new truck after an engine failure. This not only creates waste in junkyards, but is often a waste of money as well! We can have your truck’s engine running like-new with a complete engine overhaul. In some cases, due to outdated factory components, rebuilt engines can actually provide better performance than before they were driven off the seller’s lot. We have the parts and the experience to service engines from many different manufacturers including Caterpillar, Cummins, Detroit Diesel, and Duramax.

Commercial Vehicle Inspection Program (CVIP)

In partnership with provincial and federal regulatory authorities, we provide CVIP services for trucks, trailers, school buses and other commercial vehicles. We fulfill all program requirements, including maintenance, records and inspection so you’re in compliance at all times.

Chassis Dynamometer Services

We can check the horsepower rating of your engine to see if it's up to factory spec. The dynamometer is also useful for engine break-ins as well as leak diagnosis.
