Oversized Pressure Regulator Valve Kit 845RE, ZF8HP45, ZF8HP55, ZF8HP70 (Sonnax)

Vehicles equipped with Chrysler 845RE and ZF8HP45, ZF8HP55 and ZF8HP70 transmissions often develop erratic or high line pressure due to excessive wear in the OE pressure regulator valve bore and/or sleeve. This wear allows critical oil loss, preventing proper line pressure regulation. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 35740-01K renews pressure regulator action for revived line pressure control in all ranges.
