How it works
Poor pressure rise can cause premature failure. Valve bodies set aside because of throttle valve sticking can be put back in service.
Addresses sloppy 1-2 shifts, erratic 4-3 shifts, throttle valve sticking and inadequate line pressure rise, and extends band life.
A high performance version (K200-4R-HP) for street rods, racing and extreme heavy duty use adds a big TV boost valve and valve body modifications that keep apply pressures up and deliver them quickly to the band and clutches.
