Park - Engine Running (Mechanical Powerflow)

Note

The component callouts in the text refer to the component callout numbers in disassembled views. Disassembled Views The transmission is in the park position. The park pawl actuator assembly (602) engages the park pawl (614) with the lugs on the output carrier assembly (73). The output carrier assembly (38) is held stationary, preventing the vehicle from moving.

1. Power from Torque Converter The power flows through the turbine shaft (568) into the output sun gear (70). Powerflow continues through the input carrier (62) which drives the direct overdrive sun gear shaft (65) and direct overdrive sun gear (68). The direct overdrive sun gear drives the direct overdrive carrier (67) pinion gears.
2. 1-2-3-4-6-7-8-10 Reverse Clutch Assembly The 1-2-3-4-6-7-8-10 reverse clutch is applied and is driven by the direct overdrive carrier (67) pinion gears.
3. Powerflow Terminated The turbine shaft (568), output sun gear (70), input carrier (62), direct overdrive sun gear shaft (65), direct overdrive sun gear (68), direct overdrive carrier (67) and triple clutch housing (66) rotate freely, powerflow is terminated.
4. Vehicle Held Stationary With the park pawl (614) engaged, the vehicle cannot move forward or backward.
5. 1-2-8-9-10 Reverse Clutch The 1-2-8-9-10 reverse clutch is applied in park in preparation for a shift into either 1st or reverse. This aids shift timing as only one clutch will need to be applied to achieve either range. The 10 Speed RWD is designed to have four components applied for each gear range, Also in each forward range, the design includes that only one component will need to be applied as another component releases.
6. 1-2-3-4-5-6 Reverse Clutch The 1-2-3-4-5-6 reverse clutch is applied in park in preparation for a shift into either 1st or reverse. This aids shift timing as only one clutch will need to be applied to achieve either range. The 10 Speed RWD is designed to have four components applied for each gear range, Also in each forward range, the design includes that only one component will need to be applied as another component releases.
