Coast Clutch Releases

WARNING: This page is about a different variant/trim than selected.
Coast Clutch:

When the 4-5 shift valve is shifted to the released position, coast clutch feed fluid is blocked and coast clutch fluid exhausts through the valve allowing the coast clutch to release.

4-5 Shift Valve:

Coast clutch fluid passes through the 4-5 shift valve and into the 123 circuit and on to the 3-4 shift valve where it exhausts.
