TCI 2004R/ 700R4 Lockup Wiring Kit

Universal Lock-Up Wiring Kit for GM 700R4. 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.

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.

Fully adjustable vacuum switch automatically locks and unlocks converter with engine vacuum. Manual override option allows complete control over lockup. Constructed from OEM connectors and oil resistant wire; includes gasket, wiring harness, vacuum switch, 4th gear pressure switch, splice connectors and mounting screw.
