Veteran-owned and women-owned Summit Automotive has operated on El Cajon Boulevard in La Mesa's Grossmont area since 1982, building a transmission and drivetrain specialty that now covers full mechanical repair for domestic and imported vehicles. The facility rebuilds automatic, manual, and CVT transmissions using Jasper remanufactured assemblies and Southbend clutch components, performing post-collision drivetrain assessments that often follow structural repair at shops like Caliber Collision. Amsoil full-synthetic lubricants and BG fluid-exchange products anchor the preventive-maintenance program, covering every system from engine oil to differential fluid. Service extends to Arabic-, English-, and Spanish-speaking clients and includes powertrain work that dealer service departments at Sedano Ford often route to independent specialists once factory coverage expires. Technicians perform complete teardown and reassembly of transfer cases and all-wheel-drive differentials, restoring torque-split components to factory specification under a three-year parts-and-labor warranty.
