First gear
In first gear, engine torque flows from the flex plate to the flywheel and pressure plate A. Pressure plate A is engaged and torque is transferred to clutch disc A, which is on the engine side of the dual clutch assembly. From clutch disc A, torque flows to input shaft A (the inner, solid shaft). The small gear on the end of input shaft A transmits the torque to the first gear of output shaft A. In first gear, the 1-5 synchronizer on output shaft A engages first gear and allows torque to flow from the first gear to the output shaft. Torque is transmitted to the differential via the output shaft A pinion.
Second gear
In second gear, engine torque flows from the flex plate to the flywheel and pressure plate B. Pressure plate B is engaged and torque is transferred to clutch disc B, which is on the transmission side of the dual clutch assembly. From clutch disc B, torque flows to input shaft B (the outer, hollow shaft). The small gear near the middle of input shaft B transmits the torque to the second gear of output shaft A. In second gear, the 2-6 synchronizer on output shaft A engages second gear and allows torque to flow from the second gear to the output shaft. Torque is transmitted to the differential via the output shaft A pinion.
Third gear
In third gear, engine torque flows from the flex plate to the flywheel and pressure plate A. Pressure plate A is engaged and torque is transferred to clutch disc A. From clutch disc A, torque flows to input shaft A. The gear nearest the clutch on input shaft A transmits the torque to the third gear of output shaft B. In third gear, the third gear synchronizer on output shaft B engages third gear and allows torque to flow from the third gear to the output shaft. Torque is transmitted to the differential via the output shaft B pinion.
Fourth gear
In fourth gear, engine torque flows from the flex plate to the flywheel and pressure plate B. Pressure plate B is engaged and torque is transferred to clutch disc B. From clutch disc B, torque flows to input shaft B. The large gear on the end of input shaft B transmits the torque to the fourth gear of output shaft B. In fourth gear, the 4-R synchronizer on output shaft B engages fourth gear and allows torque to flow from the fourth gear to the output shaft. Torque is transmitted to the differential via the output shaft B pinion.
Fifth gear
In fifth gear, engine torque flows from the flex plate to the flywheel and pressure plate A. Pressure plate A is engaged and torque is transferred to clutch disc A. From clutch disc A, torque flows to input shaft A. The large gear on the end of input shaft A transmits the torque to the fifth gear of output shaft A. In fifth gear, the 1-5 synchronizer on output shaft A engages fifth gear and allows torque to flow from the fifth gear to the output shaft. Torque is transmitted to the differential via the output shaft A pinion.
Sixth gear
In sixth gear, engine torque flows from the flex plate to the flywheel and pressure plate B. Pressure plate B is engaged and torque is transferred to clutch disc B. From clutch disc B, torque flows to input shaft B. The large gear on the end of input shaft B transmits the torque to the sixth gear of output shaft A. In sixth gear, the 2-6 synchronizer on output shaft A engages sixth gear and allows torque to flow from the sixth gear to the output shaft. Torque is transmitted to the differential via the output shaft A pinion.
Reverse gear
In reverse gear, engine torque flows from the flex plate to the flywheel and pressure plate B. Pressure plate B is engaged and torque is transferred to clutch disc B. From clutch disc B, torque flows to input shaft B. The small gear in the middle of input shaft B transmits the torque to the second gear of output shaft A. The second gear has a fixed connection to the intermediate gear. The intermediate gear is in mesh with the reverse gear on output shaft B. In reverse gear, the 4-R synchronizer on output shaft B engages reverse gear and allows torque to flow from the reverse gear to the output shaft. Torque is transmitted to the differential via the output shaft B pinion.
