4L80E, 4L85E Reprogramming Kit with Manual Shift Control
This TransGo Reprogramming Kit provides full manual control for upshifting and downshifting 1st through 4th gear, there are no automatic shift functions retained. 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. Its all about providing the required gears when there are no computer controls. Similarly, the internal vacuum modulator setup provides an aggressive line pressure curve and regulation without the need for a TCM.The included valve body, pump and internal components are calibrated to work in concert with an aggressive line pressure curve that will greatly improve the overall durability and shift feel of the transmission. Also, the laminated triple separator plate provides dual feed for the 3rd gear clutch without having to dismantle the transmission. Dual feeding the 3rd gear clutch triples the torque capacity of the 3rd gear clutch which is the Achilles heel of this transmission. In addition, the included highly improved wide land design boost valve and bushing resists wear so that pressure regulation functions consistently for the long haul. Lastly, the EPC boost pressure relief valve system provided helps protect against accidental runaway boost pressure to stop the case and direct drum failure.There are no provisions included in this kit for the torque converter clutch operation, therefore, if you are going to run a TCC you will need to wire it up to a toggle switch for which parts and instructions are not furnished. On the other hand, if you are going to install a converter with NO clutch, then the installation of #48-CCV is advised for maximum coupling and cooling.
