MultiTransmission Compatibility This wiring harness is specifically crafted for NCR60E, 4L60E, 4L65E, and 4L70E transmissions from 19932008, providing seamless integration in both 2WD and 4WD vehicles. Performance Control Acts as the key interface between the engine control module and the manual shift mechanism, enabling accurate clutch operation and gear shifting for responsive driving experiences. Construction Materials Features a copper core wire for conductivity; its corrosionresistant design enhances longevity while protecting against extreme temperatures. Effortless Installation Process Manufactured to meet original factory standards with robust ring terminals; this plugandplay harness allows quick setup without modifications needed. Practical applications and scenarios Replacement in a GM vehicle equipped with one of the listed transmissions (NCR60E, 4L60E, 4L65E, or 4L70E) to restore proper ECUtoshift linkage and clutch operation without custom wiring. Vehicle upgrades or engine/transmission swaps where maintaining correct ECU communication and smooth shifting is essential, including 2WD or 4WD configurations. Restoration or routine maintenance in environments with wide temperature ranges or exposure to moisture, where copper conductors and corrosion resistance contribute to reliable longterm performance.
