4l60E 4L65E Converter Conversion Valve (Non-Lock-Up Only)

Product Description

TransGo 4L6-CCV converter conversion valve kit for 1993 to 2015 GM vehicles with the 4L60E, 4L65E and 4L70E, for use with a non lock-up torque converter. It corrects converter charge and lube flow when a non-lockup converter is fitted.

Specifications

How it works

High performance or transplanted vehicles used off-road or on the strip are sometimes fitted with a converter that has no lock-up clutch. Without changes at the oil pump and valve body, this can cause a loss of coupling (slippage) and excessive heat, because the converter does not stay fully charged under heavy load and high RPM.

This drop-in kit redirects converter flow to the primary pump area so the converter stays fully charged under high load and RPM. It needs no pump machining, cross-drilling or modification to the pump or support. A TCC enable solenoid is not needed, though it can be reinstalled. The kit is compatible with TransGo's 4L60E series products.

In vehicles that still use the OE computer for transmission management, the TCM can set a lock-up performance or slip code such as P0741.
