6-Speed Transmission Power Flow

6-Speed Transmission Power Flow
The individual gear power flows for the M54B30 engine are illustrated in the next few pages. The power flows illustrated are applicable to an input torque of 300 Nm at a speed of 3500 rpm. The step-up ratio from the input shaft to the countershaft is 1.38. The input torque at the countershaft is 390 Nm.

Power flow in 1st gear





An input torque of 300 Nm produces an output torque of 1226 Nm.

Power flow in 2nd gear





An input torque of 300 Nm produces an output torque of 704 Nm.

Power flow in 3rd gear





An input torque of 300 Nm produces an output torque of 470 Nm.

Power flow in 4th gear





An input torque of 300 Nm produces an output torque of 347 Nm.

Power flow in 5th gear





The transmission output torque is equal to the input torque (1:1 direct).

Power flow in 6th gear





An input torque of 300 Nm produces an output torque of 240 Nm (overdrive).

Power flow in reverse gear





An input torque of 300 Nm produces an output torque of 1107 Nm (reverse rotation).
