Ford E40D/4R100 .500 Line Mod Valve 1989-2003Part #: 96948-05K
This .500 valve gives you much firmer shifts over the stock .372 valve and firmer shifts over the .427 valve. Some E4OD, 4R100 transmissions have soft 1-2 or 2-3 shifts, intermittent harsh shifts or poor line rise complaints. These can be caused by ECU (electronic control unit) or accumulator pressure problems and shows up when HP is added. Severe wear of the line pressure modulator sleeve allows EPC (electronic pressure control ) oil to leak past the valve and cause soft shifts. Severe wear can also cause the valve to stick or hang up, causing harsh shifts. Sun Coast offers three size variations of the line pressure modulator sleeve and valve kit that eliminate this oil loss problem.
