TransGo Automatic Transmission Reprogramming Kit - GM 4L80E / 4L85E 1991-2013
This TransGo Reprogramming Kit includes valve body, pump and internal components that are calibrated to work in concert with an elevated 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.
