Diesel Engine Repair & Rebuild
In most cases, we try to direct people towards engine rebuilds rather than replacements. They’re more cost-effective and are actually better in most cases. We use OEM parts and diagnose the actual source of the problem so that you don’t replace your entire engine with a new (often subpar model) and find that you’re still having the same issues. When we rebuild, everything is done locally and in-house so that your engine rebuild is done specifically for your truck. Overall, we’re a complete diesel engine service centre solution. In the event that a rebuild isn’t recommended, we’re also equipped to replace.


Typical engine rebuild costs range from $2,500-$4,000+ CAD

Transmission Rebuild

When it comes to transmissions, a small amount of work now can pay off huge in the future. For example, winter conditions can wreak havoc on transmissions. We can make sure you’ve got the best transmission fluid for your make and model. We specialize in diesel truck transmission diagnostic and repair because we know how important it is to properly maintain equipment. Call us if you need help figuring out the best options.

The average cost of a rebuilt transmission is $2,800 to $3,800, and the average cost of a replacement transmission is $4,000 to $8,000.

A/C (Air Conditioning)

Did you know that without regular maintenance an air conditioner loses a percentage of its original efficiency every year? This means that without proper maintenance, your air conditioning isn’t pumping at full capacity. When it comes to comfort in the summer months, strong A/C is a must.

Recharge and minor repairs typically cost between $200 and $400. Extensive air conditioning repairs can cost $1,000-$4,000 or more, depending on make and model.
