Product Description

The TCI 376600 is a universal lock-up wiring kit for GM 700R4 and 2004R transmissions used in non-computer-controlled applications. It uses OEM connectors and oil-resistant wire with a vacuum-referenced lock-up control setup.

The system automatically activates converter clutch lock-up in 4th gear under stable engine operation and disengages lock-up during acceleration or downshifting. A manual override option allows direct control over converter lock-up when needed.

The kit includes gasket, wiring harness, vacuum switch, 4th gear pressure switch, splice connectors, and mounting screw. TCI lists it for street rods, muscle cars, and pre-1993 700R4/2004R applications where the factory computer is removed.
