700R4

The four-speed Turbo Hydra-Matic 700R4 was introduced for the 1982 model year for use in Chevrolet/GMC vehicles. 1992 was the last year of widespread usage of the 700R4 (4L60). 1993 Camaro, Corvette and Typhoon were equipped with the last production 700R4's. The last design change of the 700R4 was an added checkball to the valve body. In 1992 electronic controls were added, and it became the 4L60E. The 4L60E went into service in trucks, vans, and SUVs in 1993 (for the record, some HD trucks had the 4L60) and in all RWD passenger cars (Corvette, F and B/D bodies) in 1994. In 2001, an updated version - the 4L65-E, was introduced. Five-pinion planetaries, along with a strength-improved output shaft, were improved to withstand the 300+ ft·lb of torque of the 6.0 Vortec engine.
