The valve body controls gear selection, line pressure (clamping
force), line rise (meeting torque demand), converter mode,
flow and pressure, along with shift timing and quality. The
Sun Coast valve body addresses all of these areas to enhance
transmission operation and durability. The Sun Coast valve
body allows for crisper shifts, enhanced converter operation,
cooler operating temperatures, and increased lube flow. Full
time converter feed assures lube flow while in the park position
and under high throttle conditions. Torque converter clutch
loc-up can be achieved in all forward gears when used in conjunction
with a controller. This feature is desirable for optimum exhaust
brake operation. Sun Coast offers a choice of valve body calibrations
to fit your application.
Suncoast orders require the year, make, and model of your
truck to be placed in the comments field upon checkout
to ensure your order is processed as soon as possible.
