Eliminates input shaft and drum breakage when 700R4 and 4L60E transmissions are used in high torque applications

The more horsepower and torque your engine makes, the more your transmission is challenged to deliver. The new TCI® Heavy-Duty Input Shaft and Drum Assembly is built for GM 700R4 and 4L60E transmissions required to handle over 500 ft lbs of engine torque.

Featuring a cryogenically-hardened input shaft, the assembly incorporates a specially processed heavy-duty drum with a steel reinforcement ring, which is especially important for transmissions enhanced with raised line pressure for firmer shifting.

The TCI® Heavy-Duty Input Shaft and Drum Assembly is available in two versions: one for ’85-‘97 700R4 and 4L60E transmissions and one for ’98 and newer models. Both versions are perfect for any race or high torque street application.
