This kit delivers short firm shifts for performance as well as greater overall durability, it is designed for the off-road driver only and for vehicles that do not have any TCM controls. It’s all about providing the required gears when there are no computer controls. Similarly, the internal vacuum modulator setup and the .500” boost valve (both furnished) provide an aggressive line pressure curve and regulation without the need for a TCM. This kit can be installed while the transmission is in the vehicle on 1993-2006 models only without the input speed sensor. 2007 and later models equipped with the input speed sensor require transmission removal.
