  • All rotation are viewed from the side cover.

## Component Description

Component | Function
--- | ---
Low clutch | • Transmits rotation of low clutch drum to rear internal gear • Operates in 1GR, 2GR, or 3GR position
2-4 brake | • Prevents rotation of front sun gear • Operates in 2GR, 4GR, or 5GR position
High clutch | • Transmits rotation of high clutch drum to front planetary carrier • Operates in 3GR, 4GR, or 5GR position
Reverse clutch | • Transmits rotation of reverse clutch drum to front sun gear • Operates when vehicle is reversing
Reduction brake | • Prevents rotation of direct clutch drum and prevents rotation of reduction sun gear
Low and reverse brake | • Prevents rotation of low and reverse brake hub
Direct clutch | • Transmits rotation of reduction planetary carrier to reduction sun gear • Operates in 5GR position
Low one-way clutch | • Locks clockwise rotation of front planetary carrier
Reduction one-way clutch | • Locks counter clockwise rotation of reduction sun gear
