  PREMIUM VALVE BODY
  • PREMIUM, HEAVY DUTY, REBUILT ORIGINAL EQUIPMENT VALVE BODY
  • Smart-Tech overrun clutch valve kit pre-installed
  • INCLUDES ALL NEW, TESTED SOLENOIDS & PRESSURE SWITCH
  • PROUDLY REBUILT IN THE USA BY SONNAX
 
  • Sonnax heavy duty re-manufactured valve body GM033 has been designed with the workhorse vehicle in mind. Featuring the Sonnax patented 34200-40K Smart-Tech overrun clutch valve kit pre-installed, this valve body corrects the issue of insufficient holding power by the overdrive roller clutch, the underlying cause of chronic overdrive roller clutch failure in 4L80-E units.
  • This heavy duty re-manufactured valve body also includes all-new solenoids and a new pressure switch assembly. Chronic wear points in the valve body have also been repaired by reaming and installing top-quality oversized Sonnax valves that optimize valve body function and prevent future wear. These updates correct the common symptoms of wrong gear starts, clutch and band failure, solenoid performance codes, 2-3 neutral, TCC apply and release concerns, TCC and other trouble codes, and various shift complaints.
  • To guarantee the highest level of operational performance, this remanufactured valve body is tested on state-of-the-art equipment to verify that actuator feed limit pressure, clutch pressures, and torque converter pressures meet the necessary requirements for optimum functionality.
