Superior Shift Kit, for Ford E4OD E40D 4R100 Transmission (1989-Up)
One KE40D kit does regular, heavy duty and diesel applications.
The Superior kit makes extensive pump modifications needed to avoid pump failure.
Shift slippage is a real concern in this transmission. The Superior kit cleans up this problem effectively.
The KE4OD Shift Correction Package includes a metal replacement drain back valve to replace the O.E. plastic valve. The O.E. valve can melt, cutting off lube to the overdrive planets causing failure.
This valve body kit deals with these problems:
Converter shudder
Converter burn up
Reverse problems
Weak shifts
Stack shifts
Lube problems
Front seal blow out
