Experienced Toyota U660E specialists since 1987. Free computer diagnostic, lifetime warranty on rebuilds.
The U660E is Toyota's 6-speed front-wheel-drive automatic — one of the most reliable transmissions we work on. It's in the Camry and ES350 and typically runs 200,000+ miles with proper maintenance. When they do fail, it's usually valve body solenoids or the torque converter. We see these primarily on high-mileage vehicles with neglected fluid.

The shift solenoids degrade with old fluid. Failure causes specific gear loss or erratic shifting.
Symptoms: Miss 3rd or 5th gear, harsh upshift, P0750–P0770
TCC shudder on high-mileage U660E units is usually caused by degraded fluid contaminating the converter clutch material.
Symptoms: Shudder at 40–60 mph, P0741
Valve body bore wear from extended fluid intervals causes pressure regulation issues.
Symptoms: Erratic shifts, delayed engagement, P0872
