The reverse clutch assembly in automatic transmissions is a critical hydraulic-actuated component enabling reverse gear engagement. Key points:
Function – Applies pressure to clutch packs, locking the planetary gearset for reverse output rotation.
Design – Multi-plate setup (steel/friction discs) with a piston, seals, and return springs.
Failure Modes – Burnt friction material, seal leaks, or piston sticking (causing delayed/no reverse, slippage, or abnormal noise).
Root Causes – Low fluid pressure, overheating, or contamination from worn clutch material.
