Transmissions don't usually fail without warning — they slip, they delay, they shift hard, they leak. Catching it early can mean a fluid flush and a solenoid. Ignoring it means a $3,500 rebuild. We service automatics, manuals, CVTs, and dual-clutch trans on every major make. Backed by the Supercanic network across Southern California.
Modern transmissions are computer-controlled. We pull TCM (Transmission Control Module) codes, look at shift solenoid commands, line pressure, input/output shaft speeds, and torque converter slip. The transmission tells us what's wrong if you ask the right questions.
Pink-red and clear: healthy. Dark brown, smells burnt, or has metal in it: that fluid has been telling you something for a while. We check level on a level surface at operating temperature per manufacturer procedure — many newer trans have no dipstick.
We drive the vehicle while watching live data. When does it slip? At what gear? At what temperature? Under what load? This is how we tell a solenoid problem from a clutch pack problem from a torque converter problem.
If fluid is heavily contaminated we drop the pan, inspect the filter, look at what's stuck to the magnet. Glittery fine metal = normal wear. Chunks or shavings = internal damage. The pan tells the truth.
If it's caught early — fluid and filter service, solenoid replacement, valve body service, or a TCM relearn may be all it needs. If clutch packs are gone, you need a rebuild or replacement. We're straight with you about which one.
After repair we use the OE procedure to bleed and fill (many modern trans require a scan-tool fluid level procedure), perform any required adaptation/relearn, then road test through every gear and verify no codes return.
Standard on most repairs. Parts and labor. If something we touched fails, we fix it again — no charge, no argument. That's how locally-owned shops have to operate.
