Transmission Service & Repair in Hayward, CA

A transmission problem is rarely cheap to fix — and almost never fixes itself. At S&R Motors in Hayward, our ASE-certified technicians service and repair automatic and manual transmissions, CVTs, and DCTs. We start with an honest diagnosis: sometimes it's a fluid flush, sometimes a solenoid, sometimes a clutch pack. We tell you exactly what's wrong before you authorize a single dollar of work.

Our transmission services cover scheduled fluid and filter service, leak detection and seal replacement, valve body repair, solenoid and sensor replacement, torque converter service, clutch replacement on manuals, and full rebuilds when needed. We use OEM transmission fluid — ATF, CVT, DCT, or manual gear oil — exactly matched to your vehicle, because the wrong fluid is one of the fastest ways to ruin a transmission. We also handle TCM (transmission control module) reflashes and adaptive learning resets after major service so the shift quality is restored.

Transmissions give warning signs before they fail completely: hard shifts, slipping, delayed engagement, fluid leaks, burnt-smelling fluid, or a check engine light with transmission codes. Caught early, many of these are fixable with a fluid service or a single component repair. Ignored, they almost always grow into a full rebuild. The cost difference can be 10x. We diagnose accurately so you spend the minimum needed to keep your vehicle reliable.

Stop-and-go traffic and Bay Area hills put extra heat into transmission fluid, and heat is the enemy of every transmission. We serve drivers across Hayward, San Lorenzo, Union City, Fremont, Castro Valley, and San Leandro who want their transmission inspected and serviced by ASE-certified technicians who follow factory procedures — not generic flush-and-pray shops.
