Brand: AMC
The AMC CVT3030 is a continuously variable transmission (CVT) developed by American Motors Corporation (AMC) during the 1970s. It was initially introduced in the 1973 AMC Gremlin and the 1974 Hornet models, as an alternative to conventional automatic transmissions.The CVT3030 features a pair of variable diameter pulleys containing multiple discs, connected by a variable-width belt. As the engine speed changes, the belt shifts to match the desired ratio between the engine and the drive wheels, continually changing the transmission's gear ratio, which allows smoother acceleration and better fuel efficiency.However, the CVT3030 had several reliability issues, including a tendency to overheat and become seized, which led to a high failure rate and subsequent discontinuation of the transmission by AMC in 1974. The CVT3030 has since been replaced by more advanced CVT technologies in modern vehicles.
