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
