Description
Features and benefits:
This kit includes valve body, case and pump components and modifications designed to deliver increased durability while providing short smooth shifts. These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmission. The included highly improved wide land self-cleaning design boost valve and bushing resists wear so that pressure rise keeps working properly. Lastly, the EPC boost pressure relief valve system provided helps prevent runaway boost pressure to stop case and valve body wall blow-out due to excess pressure.
Corrects/Prevents/Reduces:
High pressure parts breakage
Soft 2-3 shift
Burnt direct clutch
Slow 3-2 downshift
No upshifts
Harsh 1-2 shift
Low pressure due to solenoid filter breakup
