TM 9-2320-302-20 0011 00-4 Table 1. Transmission and Driveline Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Abnormal Activities or Responses from Transmission - Continued 5.   Engine  Overspeed  on  Full-throttle  Upshifts  - Continued. 2.  ECU input voltage low. Check   electrical   system   and   all connections     from     battery     and ECU  (WP  0010  00  or  WP 0119 00). 3.  Incorrect transmission fluid level. Correct  fluid  level  (TM  9-2320- 302-10). 4.  Piston  seals  leaking  or  clutch plates slipping in range involved. Notify Direct Support Maintenance. 6.   Excessive Slippage and Clutch Chatter. 1.  Incorrect calibration. Verify  calibration.  Notify  Direct Support Maintenance. 2.  ECU input voltage low. Check   power,   ground,   charging system, and battery functions (WP 0010 00). 3.  Throttle position sensor out of adjustment or failed. Adjust or replace throttle position sensor (WP 0006 00). 4.  Incorrect transmission fluid level. Correct  fluid  level  (TM  9-2320- 302-10). 7.   Abnormal Stall Speeds (Stall in First Range - 6-speed). High Stall Speeds. 1.  Not in gear. Select D (Drive). 2.  Low fluid level, aerated fluid. Add fluid to proper level (TM 9- 2320-302-10). 3.  C1 and C5 clutch slipping (6- speed, 1st range start). Notify Direct Support Maintenance. Low Stall Speeds. Engine not performing efficiently (may     be     due     to     plugged     or restricted  injectors,  high  altitude conditions, dirty air filters, out of time,  throttle  linkage,  electronic engine controls problem). Refer  to  Engine  Troubleshooting (WP    0006    00).    Notify    Direct Support Maintenance. 8.   Overheating in All Ranges. 1.  Aerated  fluid  -  incorrect  fluid level. Adjust  fluid  to  proper  level  (TM 9-2320-302-10). 2.  Engine overheat. Correct   overheat   situation   (WP 0006 00). 3.  Inaccurate temperature gage. Replace gage (WP 0062 00). 4.  Fluid cooler lines restricted. Remove     restrictions,     clean     or replace    lines    (WP    0122    00). Notify Direct Support Maintenance. 9.   Fluid   Comes   out   Fluid   Fill   Tube   and/or Breather. 1.  Dipstick loose. Tighten cap. Replace if necessary (WP 0121 00).
