Driving Clutches: Notes
WARNING: This page is about a different variant/trim than selected.
The three input clutches are responsible for driving different components of the planetary geartrain.
NOTE:
See DIAGNOSIS AND TESTING for a collective view of which clutch elements are applied at each position of the selector lever.
The underdrive clutch is hydraulically applied in first, second, and third (direct) gears by pressurized fluid against the underdrive piston. When the underdrive clutch is applied, the underdrive hub drives the rear sun gear.
