(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 cutout
cylinder is okay, replace transmission control valve (page
3-341) and forward to general support maintenance for repair
(spool and spring must be checked).
(4) Replace transmission control valve (page 3-341) and forward
to general support maintenance. Main pressure regulator
spring is broken or spool is sticking.
(5) Charging pump is worn. Replace (page 3-344) and forward to
general 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, transmission
must be removed and replaced (page 3-330). Transmission must be
disassembled and new sealing rings installed on reverse, for-
ward, or high clutch piston.
If pressure gage indication was too high, replace transmission
control 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 gage
hose from transmission control valve port. Reinstall clutch
pressure 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 converter
temperature sending unit was removed. Be sure pressure gage hose is
long enough so that you can read gage from operator’s seat in cab.
