Silverado 2500HD and 3500HD, GMC Sierra, and the Duramax-and-Allison combination that makes them worth owning — serviced where the truck sits.
Answering calls day & night across Miami-Dade and Broward. Se habla español.
What makes a Chevrolet or GMC diesel truck worth owning is the pairing: a strong 6.6L engine and a transmission with a genuinely good reputation behind it. What that means diagnostically is that the two need to be looked at together. A shudder under load, a flare between gears or a limp-mode event can come from either side, and a shop that only reads engine codes will hand you back a truck that still does it. We diagnose the pair, plus the front end, brakes and AC that a working Silverado wears through in Miami traffic.
Duramax and Allison diagnosed together, because the symptoms overlap constantly.
Silverado and Sierra HD pickups, plus 3500 chassis cabs with service and dump bodies.

It can genuinely be either, which is why we look at both. Torque converter behaviour and engine misfire produce similar complaints, and testing tells them apart quickly.
Yes. We diagnose shift quality, limp mode and pressure faults alongside the engine rather than sending you to a separate transmission shop for the diagnosis.
All of them, from the earliest LB7 through the current L5P. The generation changes the likely fault list significantly, so we always start there.
