POWER FLOW The transmission must efficiently transfer the engine's power, in terms of torque, to the vehicle's rear wheels. Knowledge of whattakes place in the transmission during torque transfer is essential when troubleshooting and making repairs. 1. 2. 3. 4. 5. 6.
Power (torque) from the engine is transferred to the input shaft and drive gear. Torque is transferred to the countershaft drive gear. Torque is delivered along the countershaft to all countershaft gears. Torque is transferred to "engaged" mains haft gear. The cross section illustrates 1st speed gear position. Engaged mainshaft gear internal clutching teeth transfers torque to mainshaft through synchronizer assembly. Mainshaft transfers torque directly to driveshaft through rear yoke.
