The 8-speed automatic transmission planetary gearset is a core torque-multiplying component. Key points:
Layout – Typically uses Lepelletier design: 1 Ravigneaux + 1 simple planetary set for compact, efficient gear spread.
Function – Enables 8 ratios via controlled clutch/band engagement (gear transitions under load).
Durability – Hardened steel gears with precision-ground teeth; carrier bushings withstand high radial loads.
Failure Modes – Bearing wear, cracked carriers, or pitted gears (causing whine, slippage, or shift flares).
