Drive Chain and Sprockets
WARNING: This page is about a different variant/trim than selected.
A chain drive transfers torque from the torque converter turbine to the planetary gearsets. The chain drive is composed of the following components:
- Reverse/overdrive ring gear assembly which acts as a drive sprocket
- Driven sprocket
- Drive chain
The drive chain connects the reverse/overdrive sun gear with the driven sprocket. The final drive sun gear located on top of the driven sprocket meshes with the final drive gearset.
The final drive consists of a planetary gearset that transfers and multiplies torque from the planetary gearsets to the differential. The final drive consists of the following components:
- Final drive sun gear: is chain driven by the reverse/overdrive ring gear assembly and transfers torque to the final drive carrier.
- Final drive carrier: the final drive carrier acts as the driven member and is part of the differential case.
- Final drive ring gear: is held by the converter housing and is always the held member of the final drive planetary gearset.
