Automatic Transmission/Transaxle: Description and Operation
DESCRIPTIONTransaxle Cross-Sectional View:
This transaxle combines a three speed automatic transmission and a differential to form a single powertrain component. Both are housed in a compact, one-piece case.
LOCATION
When installed in the vehicle, the engine/transaxle assembly is mounted transversely with the ATX on the LH side of the engine compartment.
CONSTRUCTION
This transaxle uses a torque converter, a compound planetary gear set, one band, a single one-way clutch, and three friction clutches.
OPERATION
Band Application Chart:
These components are applied as necessary to transmit engine torque through a compound planetary gear set. The gear set provides three forward gear ratios and one reverse. The planetary gear set transmits engine torque to the input gear which meshes with the idler gear. Meshing with the idler gear is the final drive (output) gear which is riveted to the differential case. When power-flow reaches the differential, engine torque flows outward to the wheels through the differential gears.
