This TransGo 4L6-CCV valve kit fits 1993 to 2015 General Motors vehicles equipped with the 4L60E, 4L65E and 4L70E automatic transmission.
When used in high performance or transplanted vehicles for off-road or strip use at times there may be a desire to eliminate the lock-up clutch function and fit the transmission with a torque converter with the lock-up clutch omitted. However, unless internal transmission modifications are made at the oil pump and valve body, doing this can result in a loss of coupling complaint-slippage and excessive heat build-up due to the converter not staying fully charged with fluid under heavy load and high RPM.
Features and benefits:
This TransGo converter flow correction kit provides you with an easy-to-install, drop-in solution, that redirects converter flow to the primary pump area and allows the converter to stay fully charged under high load and RPM. This new valve system does not require any pump machining, cross-drilling or any modification to the pump or support. It does not require a TCC enable solenoid; however, you can reinstall it if you wish. This kit is fully compatible with our enter line of products for the 4L60E series transmission.
Running a non-lock-up converter while driving in an overdriven ratio increases transmission operating temperature and can cause overheating. For this reason, it is always best to add a cooler. Transmission removal is required for installation. Lastly, please note that the computer must have a state an EPA legal reflash for non-lockup use when used in vehicles that still utilize the OE computer control system for transmission management to prevent the TCM from setting a lock up performance or slip code such as P0741.
