Description

Part #: 376600

This easy-to-install system from TCI allows hands-free, automatic activation of the torque converter clutch in 4th gear under stable engine operation and disengages the clutch when accelerating or down shifting. The Universal Lock-Up Kit is needed when installing a 700R4 or 2004R transmission in a non-computer controlled application, such as a street rod or muscle car, or when removing the factory computer in pre-1993 applications that utilize a 700R4 or 2004R transmission.

This TCI Universal Lock-Up Kit for GM 700R4 works by referencing engine vacuum to automatically engage or disengage the torque converter lock-up clutch. Vacuum reference can be overridden to engage or disengage lock-up.
