Section III.   PRINCIPLES OF OPERATION 1-10.   POWERTRAIN Figure 1-12.   Powertrain Power  for  the  vehicle  is  provided  by  a  diesel  engine  (1,  Figure  1-12)  which  is  coupled  directly  to  an  automatic transmission (2).   Power from the automatic transmission is transferred to the transfer case (3) and on to the front steering and rear drive axles (4, 5, and 6) through a series of drive shafts and universal joints.   The vehicle drive train is  enhanced  by  the  use  of  an  electronically  controlled  seven-speed  transmission.    The  primary  components  of  the Allison MD3070PT transmission consist of either a WTEC II Transmission Electronic Control Unit (ECU) Pushbutton Shift Selector (WTEC II TEPSS) or a WTEC III Transmission Pushbutton Shift Selector (WTEC III TPSS) coupled with a WTEC III transmission ECU; a control module located directly beneath the transmission main housing; a Throttle Position Sensor (TPS) which detects the percentage of throttle being used; engine, turbine, and output speed sensors which, in combination with each other, send information to the ECU to provide the smoothest possible shifting and allow the ECU to monitor overall transmission performance. 1-15
