Sonnax Ford Lincoln Mercury E4OD Line Pressure Modulator Valve .500 4R100 Transmission
OPT Product Code: SNX-96948-05K$46.84
Product Details
Some E4OD and 4R100 transmissions have soft 1-2 or 2-3 shifts, intermittent harsh shifts or poor line rise complaints. This can be either ECU (electronic control unit) related or accumulator pressure related. These complaints may be caused by severe wear of the line pressure modulator sleeve allowing EPC (electronic pressure control) oil to leak past the valve and cause soft shifts. Severe wear will also cause the valve to intermittently stick or "hang-up" causing harsh shifts. Sonnax now offers a large (.500") diameter line pressure modulator plunger valve and sleeve kit 96948-05K that eliminates this oil loss problem with closely held tolerances. Our sleeve has been manufactured from carbon steel and the valve from hardened alloy steel to prevent excessive wear. The sleeve has an o-ring added, to help prevent excessive EPC oil loss. The valve incorporates annular grooves to properly center the valve in the sleeve and eliminate side loading, which can lead to excessive wear. Note: This part may require the PCM being recalibrated. Warning! Extreme High Performance Only! This valve will dramatically increase shift firmness. This is not recommended for the diesel applications.
