Frequently Asked Questions
Do you service Chevrolet, GMC, Buick and Cadillac?
Yes, all four GM brands, from Silverado and Sierra trucks to Equinox, Enclave and Escalade.
What causes the tick in my Silverado V8?
On many 5.3 L and 6.2 L engines with cylinder deactivation, a ticking noise with misfires can be a collapsed lifter. Diagnose it early, before it damages the camshaft.
Why does my GM truck shudder at highway speed?
On some 8-speed automatics, a torque converter shudder is fixed with a fluid flush using GM’s updated fluid. We confirm the cause first.
Do you use ACDelco parts?
We use ACDelco or equivalent quality parts. See our page on ACDelco parts.
Will having the work done at an independent shop affect my warranty?
No. Using an independent shop for maintenance and repairs does not void your new-vehicle warranty. Keep your invoices; we document the parts and work on every job.
