700R4/4L60E/4L65E/4L70E

This fully CNC machined shaft is a direct replacement for the failure prone OEM shaft. It will retro-fit all 4L60E, 4L65E, and 4L70E transmissions used in extreme duty applications. The shaft is machined from 300M steel billet blanks and features a revised profile and oiling hole locations for a vast improvement in durability. Reluctor ring is not included.

This kit allows fully automatic operation of the torque converter clutch in 4th gear when retro-fitting a vehicle with a 700R4 transmission, or in 1982-1993 700R4 equipt GM vehicles that no longer use the factory ECM to control torque converter clutch strategy.

Increased line pressure, servo piston apply ratio, and engine power output can quickly fail the OEM band anchor pin in short order resulting in slipping or loss of second gear. This upgraded component is fully CNC machined from heat treated steel billet material that will not fail when subjected to extreme loading conditions.
