The transmission must efficiently transfer the engine's Knowledge of what takes place in the transmission and making repairs become necessary.
power, in terms of torque, to the vehicle's rear wheels. during torque transfer is essential when trouble-shooting
Front Section Power Flow (All Models)
Auxiliary Section Power Flow: LO-LO (8-Speed "LL" Models)
Power (torque) from the vehicle's engine is trans- ferred to the transmission's input shaft.
Splines of input shaft engage internal splines in hub of main drive gear.
Torque is split between the two countershaft drive gears.
Torque is delivered along both countershaft to mating countershaft gears of "engaged" ma shaft gear. The following cross section views (Figures 2-4) illustrate a 1st/5th speed gear engagement. Figure 1 illustrates the engagement of the Lo Speed Gear.
Internal clutching teeth in hub of engaged main- shaft gear transfers torque to mainshaft through sliding clutch.
Mainshaft transfers torque directly to auxiliary drive gear.
The auxiliary drive gear splits torque between the two auxiliary countershaft drive gears.
Torque is delivered along both auxiliary counter- shaft to the mating "engaged" deep reduction gear on output shaft.
Torque is transferred to output shaft through slid- ing clutch.
Output shaft delivers torque to driveline as LO-LO.
