Automatic Transmission Repair and Service: Diagnose, Maintain, Fix Gearboxes

Is your automatic slipping, shifting hard, or throwing a code? This system-specific guide teaches the serious home mechanic how automatics really work - and how to service, diagnose, and fix them. You'll learn how to: pick the right transmission fluid and do a proper drain-and-fill, pan drop, or flush; check fluid on both dipstick and sealed "lifetime" units; read transmission trouble codes and live data; diagnose slipping, flare, harsh or late shifts, no-drive, and limp mode; service solenoids, sensors, and the valve body; fix cooler lines, seals, and leaks; and decide between rebuild, replace, and remanufactured. With 60 full-color figures, a transmission road-test method, and symptom-to-cause tables. Covers torque converters, planetary gearsets, and modern electronic controls.
