Neutral - Engine Running
Third Clutch - Released
Reverse Clutch. Released
Low Band . .Released
Second Clutch. Released
Sprag - Locked
In neutral, the low band and all clutches are released. With this condition, no member of the planetary gear set is
held and there is no reaction member. All gears are free to rotate around their own axis and no torque is trans-
mitted to the planet carrier assembly and output shaft.
Park - Engine Running
The same power flow conditions in the neutral position are in effect in the park position. Additionally, mechan-
ical linkage actuates a parking pawl which engages with the splines in the periphery of the governor assembly.
Since the governor assembly is splinad to the output shaft, the parking pawl holds the output shaft locked to the
extension, preventing the vehicle from rolling.
