Line Pressure Booster Kit Sonnax AODE 4R70E 4R70W 4R75E 4R75W

Line Pressure Booster Kit for 4R70E, 4R70W, 4R75E, 4R75W, AODE The AODE/4R70W line rise control operates differently compared to most units. In this system, the EPC oil directly influences the forward pressure by acting on the spring end of the PR valve. Notably, the original equipment (OE) boost assembly only enhances pressure when in reverse. This unit has not traditionally allowed for the use of a larger ratio boost valve to escalate line pressure. Sonnax has engineered a unique boost assembly that incorporates an additional boost valve. This supplemental valve is designed to increase line rise during forward gear engagement. Mirroring the design of other Sonnax line pressure booster kits, this special boost valve expands the EPC reaction area, offering a gradual and necessary increase in pressure. This assembly is paired with a spring that is roughly 10% stronger than the OE version. Despite its strength, it is designed to be less aggressive than other aftermarket kit springs. This
