HIGH TRANSMISSION OIL TEMPERATURE (CONV TEMP GAGE INDICATES EXCESSIVE TEMPERA-TURE) (Cont).Step 1. (Cont).a.b.c.d.(Cont).(2) Replace transmission filter (refer to TM 5-3805-262-20).(3) Clutch cutout cylinder is being activated. Check clutch cut-out cylinder (refer to TM 5-3805-262-20). If clutch cutoutcylinder is okay, replace transmission control valve (page3-341) and forward to general support maintenance for repair(spool and spring must be checked).(4) Replace transmission control valve (page 3-341) and forwardto general support maintenance. Main pressure regulatorspring is broken or spool is sticking.(5) Charging pump is worn. Replace (page 3-344) and forward togeneral support maintenance for repair.If pressure gage indication was correct with transmission con-trol lever in neutral but was low in R, F, or H, transmissionmust be removed and replaced (page 3-330). Transmission must bedisassembled and new sealing rings installed on reverse, for-ward, or high clutch piston.If pressure gage indication was too high, replace transmissioncontrol valve (page 3-341) and forward to general support main-tenance. Spool in main pressure regulator is not moving freely.If pressure gage indication was okay, disconnect pressure gagehose from transmission control valve port. Reinstall clutchpressure switch in control valve port (refer to TM 5-3805-262-20). Go to step 2 below.Step 2. Remove converter temperature sending unit (refer to TM 5-3805-262-20).Connect pressure gage hose to transmission port from which convertertemperature sending unit was removed. Be sure pressure gage hose islong enough so that you can read gage from operator’s seat in cab.2-96
