    This TransGo 48-CCV valve kit fits 1991 to 2013 General Motors vehicles equipped with the 4L80E and 4L85E 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, 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 kit is fully compatible with our enter line of products for the 4L80E series transmission.

    Running a non-lock-up converter while driving in an overdriven ratio increases the 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.

    Corrects/Prevents/Reduces:
    • Corrects converter charge and lube flow when using non-lockup converter
    Includes:
    • Lock-up valve
    • Converter limit valve spring
    • (2) Plugs
