Product Description

The TCI 376600 is a lock-up wiring kit for 700R4 and 2004R transmissions in non-computer controlled applications. It includes an external wiring harness, internal wiring harness, normally open fourth gear pressure switch, number 4 machine screw, splice connectors, and a vacuum switch.

This kit allows hands-free automatic activation of the torque converter clutch in 4th gear during stable engine operation, then disengages the clutch during acceleration or downshifting. It is useful when installing a 700R4 or 2004R into a street rod or muscle car, or when removing the factory computer from pre-1993 applications using those transmissions.

The harness is constructed from OEM connectors and oil-resistant wire, and the kit is Made in USA. It gives non-computer controlled builds a cleaner lock-up control path while preserving the required 700R4 and 2004R transmission compatibility.
