Reverse Clutch Applies

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

The #7 Checkball (Reverse/Reverse Clutch)

The #7 checkball is located in the valve body. The checkball is seated against the spacer plate in order to force reverse fluid through orifice #12 before the fluid enters the reverse clutch circuit.

The 1-2 Shift Valve

This valve operates in the downshifted position. The valve allows orificed PRN fluid to enter the Low & Reverse band apply fluid passage. Low & Reverse band apply fluid is then routed to checkball #6.

The #6 Checkball (Low/Reverse Band Apply/Reduce)

The #6 checkball is located in the valve body. The checkball is seated against the Low & Reverse band reduce passage. The checkball routes fluid into the Low & Reverse band apply circuit. Low & Reverse band apply is then routed to the Low & Reverse servo piston and actuates the piston.

The #4 Checkball (Reverse Clutch)

The #4 checkball is located in the accumulator housing. The checkball is unseated by reverse clutch fluid, allowing reverse clutch pressure to actuate the reverse accumulator piston.

Reverse Accumulator Assembly

Primary accumulator fluid on the spring side of the reverse accumulator piston is forced back through its circuit to the 1-2 & 3-4 accumulator valve. The 1-2 & 3-4 accumulator valve then regulates the exhaust of primary accumulator fluid.
