Correction:
Recover hydraulic control and restore normal solenoid supply pressure by reconditioning the bore and installing Sonnax oversized solenoid modulator valve kit.
Toyota vehicles equipped with listed transmissions may exhibit driveability problems caused by erratic oil pressure delivered to various solenoids. Low cooler flow, solenoid codes, impaired TCC operation, and various shift concerns are common results of this abnormal pressure. As the OE solenoid modulator valve oscillates and strokes over time, bore wear occurs that prevents proper regulation of solenoid supply pressure, flooding or starving the solenoids and causing erratic solenoid operation. Reconditioning the bore and installing this oversized solenoid modulator valve kit shores up the hydraulic integrity of this circuit for renewed solenoid performance and trouble-free shifting.
