Low & Reverse Band Applied

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

Low & Reverse Servo

Low & Reverse band reduce fluid from the 1-2 shift valve seats checkball #6 against the Low & Reverse band apply passage. Fluid is then routed to the spring side of the Low & Reverse servo piston, and into the reverse clutch circuit. In this gear range the Low & Reverse band remains applied, despite the spring force and the Low & Reverse band pressure acting on the Low & Reverse servo piston.

#6 Checkball (Low & Reverse Band Apply, Reduce)

The #6 checkball is held against the Low & Reverse band apply circuit. The checkball routes fluid to the reverse clutch circuit. Reverse clutch fluid is then routed to the manual valve where the fluid exhausts.

1-2 Shift Valve

Operating in the downshifted position, Low & Reverse band apply fluid passes through the valve and enters the orificed PRN circuit. Orificed PRN fluid is the routed to the manual valve where the fluid exhausts.
