Used Transmissions
General Motors Company first developed the Turbo-Hydramatic 400 transmission in 1964 for use in Cadillac vehicles. These GMC transmissions have three forward speeds and a reverse gear. They were used to replace the Buick Dynaflow and the original Hydra-Matic. The THM400 torque converter is mated with a Simpson planetary gearbox and also incorporates a Switch-Pitch variable-pitch stator. GMC transmissions then released the THM350 after the THM400. The THM350 was released later because of its reputation for known failure when subjected to high torque and stress. The Turbo Hydra-matic 350 was first released in 1969 and but was not created by the Hyrdra-matic Division of GMC. The THM350 was actually created by Chevrolet and Buick but was used as the platform for the Hydramatic 200-4R, later created by GMC. Due to the 1973 Arab Oil Embargo, GMC decided to phase in a new type of transmission that was better on fuel economy. In 1976, GMC released the THM200 with overdrive – a lightened, aluminum version of the THM350. It was often changed out in bigger engines because it was not able to handle the horsepower of the V8.

By 1980, the Hydramatic 200R4 and 700R4 transmissions were making an appearance and would soon replace the THM350 and the THM200. The 200R4 was an improved version of the THM200 that was featured on high horsepower vehicles such as the Buick Grand National and the 1982 Chevy Corvette. The 200R4 came with a lockup torque converter and many different configurations for its gear ratios, depending on the vehicle. Because of its similarities to the THM200, THM350, and the THM400, the 200R4 often replaces these older GMC transmissions. The switch is often uncomplicated with minor adjustments. This upgrade also allows the driver to pick up an additional overdrive gear which it didn't have. The Turbo Hydramatic 700R4 was introduced in 1982 for use in GMC vehicles and was featured on the 1993 Camaro, Corvette, and Typhoon. These GMC vehicles were equipped with the last production 700R4s. The 700R4 was renamed the 4L60 and electronic controls were added. After the year 2000, and updated 4L65-E was introduced from GMC transmissions. This transmission came with a five-spline planetary, a stronger output shaft, and could even withstand the 300 plus pounds of torque put out by a 6 liter Vortec engine.
