A760E: solenoid pack or rebuild. 8-speed: fluid service first, solenoid if codes indicate. More frequent ATF WS changes recommended for spirited drivers.
Toyota ATF WS - change every 40,000 miles for sport driving
Verify exact spec on the dipstick label or owner's manual before fill. Recommended change interval: every 60,000 miles for normal driving, 30,000 miles under severe service (towing, stop-and-go, hot climates). Pan service typically takes 6 - 8 quarts; a full fluid exchange takes 10 - 14 quarts depending on cooler-line capacity.
2 - 3 days.
Fluid service and inspection complete the same day. Solenoid or sensor replacement: 1 day. Torque converter or seal repair: 2 - 3 days. Full rebuild with road test: 4 - 6 days. Time estimates assume parts in stock - call (312) 626-8759 to verify availability for your specific vehicle.
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
Not if it's a new development. A760E or 8-speed solenoid wear causes inconsistent shift quality. Diagnostic first.
Very - when properly maintained. Sport driving accelerates fluid degradation; change ATF WS every 40k miles if you drive hard.
2 - 3 days.
Different units - IS350 RWD uses A760E; GS350 uses a different Aisin unit. Same Toyota/Lexus quality.
