![]() ![]() 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. Lastly, the EPC boost pressure relief valve system provided helps protect against accidental runaway boost pressure to stop the case and direct drum failure. 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. Dual feeding the 3 rd gear clutch triples the torque capacity of the 3 rd gear clutch which is the Achilles heel of this transmission. Also, the laminated triple separator plate provides dual feed for the 3 rd gear clutch without having to dismantle the transmission. 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. Similarly, the internal vacuum modulator setup provides an aggressive line pressure curve and regulation without the need for a TCM. It’s all about providing the required gears when there are no computer controls. It is designed for the off-road driver only and for vehicles that do not have any TCM controls. This kit delivers short firm shifts for performance as well as greater overall durability. This TransGo Reprogramming Kit provides full manual control for upshifting and downshifting 1st through 4th gear, there are no automatic shift functions retained. On the other hand, the runaway boost pressure problem can result in a costly broken case, direct drum and piston failure. With the low boost pressure problem, the resulting complaints are a soft 2-3 shift, direct clutch failure as well as the gear ratio and solenoid performance codes. The boost valve assembly is notorious for wear causing both low pressure as well as runaway boost pressure. Common complaints on this transmission are no upshifts, soft 2-3 shift, burnt direct frictions, broken hard parts as well as gear ratio and solenoid performance codes. This 4L80E-3 Reprogramming Kit fits 1991 to 2013 General Motors vehicles equipped with the 4L80E and 4L85E automatic transmission with gas engines only. (2) Pressure regulator valve springs, spacer, boost valve, bushing and snap ring.1-2 accumulator spring, spacer and three spacers.Second servo spacers, shims and O-rings.Provides full manual control for upshifting and downshifting 1 st through 4 th gear only.Pump and valve bore wear due to erratic pump slide bounce. ![]() Burnt forward and low/reverse clutch plates.On the other hand, if you are going to install a converter with NO clutch, then the installation of #4L6-CCV (not included in the 4L60E-3 kit, requires transmission removal) is advised for maximum coupling and cooling. 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. Lastly, there are no provisions included in this kit for the torque converter clutch operation. The instructions also include the procedure to easily convert it back to work with a factory or aftermarket TCM. ![]() This kit includes # 7-CS 3-4 clutch piston return spring kit for the input drum which reduces centrifugal 3-4 clutch apply and failure in 1 st gear at 5500 RPM or higher, transmission removal required. 2007 and later models equipped with the input speed sensor require transmission removal. This kit can be installed while the transmission is in the vehicle on 1993-2006 models only without the input speed sensor. 500” boost valve (both furnished) provide an aggressive line pressure curve and regulation without the need for a TCM. Similarly, the internal vacuum modulator setup and the. 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. This TransGo Reprogramming Kit provides full manual control for upshifting and downshifting 1 st through 4 th gear, there are no automatic shift functions retained. Common complaints on this transmission are TCC slip or shudder, code P1870 or P0894, harsh 1-2 shift, double bump shifts, 2-3 flare up, burnt 3-4 clutch plates as well as inconsistent pressure boost problems. This 4L60E-3 Reprogramming Kit fits 1993 to 2008 General Motors vehicles equipped with the 4L60E, 4L65E and 4L70E automatic transmission. ![]()
