Experience With the Big Jobs

Wrench Automotive has real-world experience with difficult mechanical work, including engine replacement, engine swaps, motor replacement, transmission replacement, and transmission swaps. We also handle other major mechanical repairs and the advanced diagnostics that usually precede them.

Wrench Automotive installs and replaces engines and transmissions. We are transparent about exactly what we do: we diagnose the vehicle, discuss the appropriate repair or replacement options, perform the installation when it's the right fit, and complete the associated mechanical work within our capabilities.

Because we don't rebuild or internally assemble transmissions in-house, we're upfront about what a replacement involves and what your realistic options are—so you can make an informed decision.

Diagnosis First

The Right Approach to Major Repairs

Serious mechanical problems rarely have a single obvious answer. A loss of power, a major noise, or a drivability issue might point to an engine problem, a transmission problem, or something else entirely.

Wrench Automotive starts by diagnosing the vehicle so we understand what's really going on. We then discuss the appropriate repair or replacement options with you, and only proceed with your authorization. We don't invent pricing, warranties, or turnaround promises—we give you a straight answer based on your specific vehicle.

We serve individual vehicle owners as well as commercial and business owners who need their vehicles—or their fleets—dependably back on the road.
