Lay the perfect foundation for work trucks and muscle cars alike with premium manufactured valve bodies from Sonnax. Heavy duty remanufactured valve body GM053-HD provides enhanced input sprag and forward clutch durability in D3 1st and 2nd Gears by engaging the overrun clutch for added holding capacity. When towing at highway speeds and wanting more throttle, manually shifting to D3 engages this enhanced protection and additional holding power.
It is also built to overcome chronic shift and converter clutch apply complaints, and provides firmer shifts and a moderately increased pressure curve to improve performance.
Numerous Sonnax valve upgrades are included to restore hydraulic clearances that lead to shift complaints, clutch distress, converter complaints and codes, solenoid issues and pressure problems. Line pressure rise has been moderately increased to overcome shift complaints, delayed engagements, and to increase holding power to the clutches.
To guarantee the highest level of operational performance, this remanufactured valve body is tested on state-of-the art equipment to verify that solenoid feed, clutch, converter and line pressures match or exceed OE specifications.
The valve body includes the following:
