Sonnax Line Pressure Booster Kit for E4OD and 4R100

The Sonnax Line Pressure Booster Kit for E4OD and 4R100 transmissions is designed to enhance transmission performance under varying driving conditions. This kit includes robust pressure regulator springs and large ratio boost valves that work in tandem to provide progressive pressure increases as driving demands intensify.

The pressure regulator springs in this kit are about 10% stronger than the original equipment (OE) and are more conservatively impactful compared to other aftermarket springs. The large ratio boost valves are engineered to deliver incremental pressure increases, particularly when it's most needed. This strategic combination of springs and valves in the Sonnax kit offers an optimal balance: a moderate increase in pressure at lower speeds, with a high-end pressure that matches or surpasses other aftermarket options.

Key Benefits:

Enables shorter shifts and enhanced torque capacity without causing harshness at low speeds.
Improves band and clutch holding capacity, thereby increasing durability.
Ensures progressive pressure increase in response to more demanding driving conditions.
Delivers all the advantages of increased line pressure without overburdening the pump at idle.
Drop-in Zip Valve™ parts for quick and straightforward installation.
