Tom's B&M Auto has been Lynnwood's go-to shop for Chevrolet owners since 1985 — trucks, SUVs and cars — a domestic staple we service daily. ASE-certified, manufacturer-equivalent OBD-II diagnostics, upfront pricing, and a 24-month / 24,000-mile warranty on every repair.
GM Tech2-compatible diagnostic scan reading GM-specific fault codes including AFM/DOD system codes, StabiliTrak, and trailer brake controller. Generic scan tools miss GM module-specific codes.
GM 6L80/8L90 transmission service uses Dexron HP — not Dexron VI. 5.3L AFM lifter replacement performed with updated lifter kits and camshaft where needed. AC Delco-specification parts used throughout.
Post-repair Tech2-compatible scan and AFM system reset. AFM disable option available for customers who want to prevent recurrence. All Chevrolet repairs backed by our 24-month/24,000-mile warranty.
GM 5.3L AFM lifter collapse is widespread on trucks and SUVs from 2007-2021. The AFM lifters deactivate 4 cylinders under light load and fail when the deactivation mechanism collapses. We replace with updated non-AFM lifter kits and can disable the AFM system in the ECU to prevent recurrence.
Pacific Northwest Chevrolet trucks develop rear drum brake adjuster corrosion that causes rear brake imbalance and premature front pad wear — a condition that's invisible until you're on a lift. We inspect and free up drum brake adjusters on every Chevy truck brake service, which most shops skip.
GM-specific codes, AFM system diagnostics, and module resets.
Updated non-AFM lifter kits with AFM disable option available.
Correct GM 6L80/8L90 transmission fluid — not Dexron VI.
