4L60E Rear Extension Housing Seal - 8681860

AC Delco 4L60E Rear Extension Housing Seal - 8681860

Genuine AC Delco rear extension housing seal for GM 4L60E automatic transmissions. Transmission seals prevent fluid from leaking at critical points including the torque converter interface and output shaft. A leaking seal can quickly drain fluid leading to catastrophic transmission failure if the fluid level drops below minimum operating requirements.

This OEM seal is manufactured to exact GM tolerances for a proper interference fit that prevents leaks under all operating pressures and temperatures. Always replace seals during rebuilds and whenever the transmission is removed from the vehicle to prevent future leaks and costly repeat removal for seal replacement.
