Sonnax heavy duty remanufactured valve body GM053-HD is built to overcome chronic shift and converter clutch apply complaints. It provides firmer shifts and a moderately increased pressure curve to improve performance, especially in truck and towing applications, plus enhanced input and Forward clutch durability in D3 1st and 2nd Gears.
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.
