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 lock-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.
No Electronics Included.

Had a bad shuttle shift problem in my 48re. Decided to do a quick VB upgrade. Easy to install, I did it in my driveway in less than an hour. Instructions could have used some better photos in the cable adjustment portion but all in all pretty straight forward. I would suggest replacing the governor pressure solinoid, pressure sensor, and overdrive lockup solinoid while your there. Shifting was spot on firm but not obnoxious deffinately worth the $$

Ive used suncoast for years. Installing the VB is a simple procedure and I have yet to have to pull a pan back off to make any adjustments.
Shifts are firm but not obnoxious. Line rise is just right and shift points are right on the money.
