Since 1994, AA Auto Repair & Transmission on University Avenue in La Mesa has provided full-service mechanical work for both foreign and domestic vehicles. The shop's transmission specialty covers complete rebuilds, torque-converter replacement, and the sourcing of low-mileage Japanese-manufactured engines and transmissions for swap installations — a service scope that often begins with emergency vehicle recovery through Tow For Less when drivetrains fail on local roadways. OBD-II computer diagnostics pinpoint check-engine faults across engine management, emissions, and ABS modules, supporting repair categories from fuel-injection servicing and timing-belt replacement to A/C compressor swaps and suspension overhauls. The shop also performs Uber and Lyft vehicle inspections required by California's TNC (Transportation Network Company) regulations, an insurance-adjacent compliance service paralleled by auto-coverage specialists like AAA La Mesa Insurance and Member Services on El Cajon Boulevard. Full transmission rebuilds include torque-converter stall-speed matching, valve-body recalibration, and band-adjustment sequencing to restore factory shift points across all forward and reverse gears.
