TRANSMISSION OIL PRESSURE TESTING
1.
Set engine idle to proper speed. DO NOT disconnect STE/lCE DCA connector once engine idle
speed has been set. (See TM 9-2320-289-20)
2.
Remove pressure tap plug
(3)
located on left side of transmission
between downshift switch connector
(2) and manual linkage. Install
appropriate transducer adapter and
cable
to
pressure
tap
(1)
and
connect cable to STE/lCE tester,
3.
Enter test codes “ 10, ” “01, ” and
“50” into STE/lCE tester.
4.
Table 5-1 lists 7 tests (“A” through
“G”)
in
which
to
measure
transmission oil pressure. Take the
pressure measurement in each test
and
record
the
result.
Record
whether the reading for each test
range was “ LOW, ” “NORMAL,” or
“HIGH. ”
If
oil
pressure
is
not
“NORMAL,” refer to Table 5-2.
