Some E4OD, 4R100 and AX4N 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. 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. Sonnax line pressure modulator plunger valve kit 96948-05K eliminates that eliminate this oil loss problem in listed units.
Sleeve is manufactured from carbon steel to prevent excessive wear
Valve is made from hardened alloy steel for better wear resistance
O-Ring helps prevent EPC oil loss
Annular grooves center valve in sleeve and eliminate sideloading
Improves shift firmness
.500" Diameter valve is larger than OE .331" and 372" sizes and will result in higher accumulator pressure and firmer than stock 1-2, 2-3 and 3-4 shifts.
