TM  1-1520-240-10            9-1-21 If indicator does not reset and engine power is required then: Land as soon as possible. If indicator does not reset and engine power is required then: 1.   EMERG ENG SHUTDOWN. 2.    Land as soon as practicable. 9-1-34.  Transmission Low Oil Pressure or High Temperature Indications. Developing trouble in the transmissions can be identified by high oil temperature or low oil pressure, as indicated by  transmission  temperature  and  pressure  indicators and cautions. If an abnormal temperature or pressure indication develops, closely monitor the caution capsu- les. The XMSN OIL PRESS (main or aux) and XMSN OIL HOT  caution  capsules  operate  independently  of  the pressure and temperature indicating system and come on when a low pressure or high temperature condition occurs. Additional information may be obtained by the flight  engineer  checking  the  MAINTENANCE  PANEL. The  transmission  temperature  and  pressure  selector switches shall be used to assist in determining the defec- tive transmission. 9-1-35.  XMSN OIL PRESS Caution. If the XMSN OIL PRESS caution capsule comes on, the following actions should be taken: AFT or AFT SHAFT (confirm AFT SHAFT with flight engineer): Land as soon as possible. FWD or COMB (MIX): 1.   Altitude — Descend to minimum safe altitude. 2.   Airspeed — 100 KIAS or Vne, whichever is slower. 3.   Land as soon as practicable. LEFT or RIGHT Engine power is required: Land as soon as possible. Engine power is not required:   1.   EMERG ENG SHUTDOWN. 2.   Land as soon as practicable. 9-1-36.  XMSN   OIL   PRESS   and   XMSN   AUX   OIL PRESS or XMSN CHIP DET Caution. Land as soon as possible. 9-1-37.  XMSN AUX OIL PRESS Caution. If the XMSN AUX OIL HOT caution capsule comes on, the following actions should be taken: MAIN XMSN, (FWD, COMB (MIX) or AFT) Main transmission oil pressure and temperature are ab- normal: Land as soon as possible. Main transmission oil pressure and temperature are nor- mal: Land as soon as practicable. 9-1-38.  XMSN OIL HOT Caution. If the XMSN OIL HOT caution capsule comes on, the following actions should be taken: FWD or COMB (MIX): Land as soon as possible. AFT transmission is indicated: 1.   Land as soon as possible. 2.   Electrical load  — Reduce as much as possible. LEFT or RIGHT Engine power is required: Land as soon as possible. Engine power is not required: 1.   EMER ENG SHUTDOWN. 2.   Land as soon as practicable 9-1-39. 712 Torque  Measuring  System  Malfunc- tions. Malfunctions in the torque measuring system can appear on the torquemeter as fluctuations, zero torque indica- tion,  sluggish  movement,  indications  that  are  out  of phase, or a stationary indication. Fluctuations in torque at steady state are indicative of an electrical malfunction within the system. If thisoccurs, proceed as follows: 1.   AC and DC Torque circuit breakers — In. 2.   N1s  —  Monitor  when  power  changes  are made insuring power outputs are matched. 3.   Fuel  flow  indicator  —  Monitor  for  matched fuel flows.
