Automatic Transmission - DPS6

System Operation

Park

In PARK (P):
- there is no power flow through the transaxle.
- the parking pawl locks the final drive.
- the engine may be started.
- the ignition key may be removed.

Reverse

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 2 to the hollow input shaft. The hollow input shaft now transmits the torque to the reverse/2nd double gear which acts as an idler gear to reverse the direction of rotation. This idler transmits torque to the reverse gear of the output shaft. The torque is transmitted to the differential via the output pinion.

Neutral

In NEUTRAL (N):
- the vehicle is able to roll.
- there is no power flow through the transaxle.
- the output shaft is not held and is free to turn.
- clutch 1 and clutch 2 are off.
- the engine may be started.

1st Gear

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the first gear of the output shaft. The torque is transmitted to the differential via the output pinion.

2nd Gear

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 2 to the hollow input shaft. The inner input shaft transmits the torque to the second gear of the output shaft. The torque is transmitted to the differential via the output pinion.

3rd Gear

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the third gear of the output shaft. The torque is transmitted to the differential via the output pinion.

4th Gear

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 1 to the inner input shaft. The inner input shaft transmits the torque to the fifth gear of the output shaft. The torque is transmitted to the differential via the output pinion.

6th Gear

The torque is introduced into the dual clutch via the flywheel. From there, the power is transmitted via clutch 2 to the hollow input shaft. The hollow input shaft transmits the torque to the sixth gear of the output shaft. The torque is transmitted to the differential via the output pinion.

Failure Modes

If a fault occurs continued motoring is guaranteed in the following limited conditions based on the failure: 1st, 3rd and 5th gear if a fault with clutch 2 and/or relational components occurs. 2nd, 4th, 6th and reverse if a fault with clutch 1 and/or relational components occurs.
