NOTE
In step 36, all shifts start from THIRD speed.
36.
Use locking pliers to shift manual selector shaft from THIRD speed to FOURTH speed; from FOURTH speed to FIFTH
speed; from FIFTH speed to SIXTH speed; from SIXTH speed to SEVENTH speed; and from SEVENTH speed to
EIGHTH speed. Record pressure gage readings for tap D, engine rpm and transmission speed.
37.
Turn hand lever until tachometer on transmission hydraulic test set reads 750 RPM.
38.
Use locking pliers to shift manual selector shaft into FIRST speed and record pressure gage readings for taps B, C and
D, engine RPM and transmission speed.
39.
Use locking pliers to shift manual selector shaft into SECOND speed and record pressure gage readings for taps B, C
and D, engine RPM and transmission speed.
40.
Use locking pliers to shift manual selector shaft into REVERSE and record pressure gage readings for taps B, C and D,
engine RPM and transmission speed.
41.
Use locking pliers to shift manual selector shaft into THIRD speed and record pressure gage readings for taps B, C and
D, engine RPM and transmission speed.
42.
Use locking pliers to shift manual selector shaft into FOURTH speed and record pressure gage readings for taps B, C
and D, engine RPM and transmission speed.
43.
Use locking plier to shift manual selector shaft into FIFTH speed and record pressure gage readings for taps B, C and D,
engine RPM and transmission speed.
44.
Use locking pliers to shift manual selector shaft into SIXTH speed and record pressure gage readings for taps B, C and
D, engine RPM and transmission speed.
45.
Use locking pliers to shift manual selector shaft into SEVENTH speed and record pressure gage readings for taps B, C
and D, engine RPM and transmission speed.
46.
Use locking pliers to shift manual selector shaft into EIGHTH speed and record pressure gage readings for taps B, C and
D, engine RPM and transmission speed.
47.
Stop engine.
48.
Compare recorded pressures with Table 1, Transmission Control Pressure Chart. If all pressures are satisfactory, trans-
mission control group is operating properly.
