The five transmissions installed on 1988 to 1992 Chevrolet trucks, according to Drivetrain.com, were the Borg-Warner T5, the Getrag, Muncie or New Venture models HM290, 5LM60 and NV3500 and the New Venture NV4500. The NV4500 appeared on 1992 full-sized trucks only. Locating the manufacturer's tag, if present, is the easiest form of identification for all models, with visual methods reserved for general identification. Positive identification of these transmissions is accomplished through internal methods, especially when differentiating the HM290, 5LM60 and NV3500 models. Since the differences between these three are internal, removing the transmission is necessary.
