TH700-R4, 4L60

This product is intended for off road use only.

This TransGo valve kit fits 1981 to 1993 General Motors vehicles equipped with the 2004R and 700R4/4L60 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 2004R and 700R4/4L60 transmission.
• Running a non-lock-up converter while driving in an overdriven ratio increases the transmission operating temperature and cause overheating. For this reason, it is always best to add a cooler. The transmission removal is required for installation.

Corrects/Prevents/Reduces:

• Corrects converter charge and lube flow when using non-lockup converter

Includes:

• USA-made hardened steel lock-up valve
• Lock-up valve pin
• Lock-Up valve slug
