HYDRAULIC DIAGNOSIS 125C-5
PRELIMINARY CHECK PROCEDURE
CHECK TRANSMISSION OIL LEVEL • CHECK AND ADJUST T.V. CABLE
CHECK OUTSIDE MANUAL LINKAGE AND CORRECT • CHECK ENGINE TUNE
INSTALL OIL PRESSURE GAGE* • CONNECT TACHOMETER TO ENGINE
CHECK OIL PRESSURES IN THE FOLLOWING MANNER:
Minimum T.V. Line Pressure Check
Set the T.V. cable to specification; and with the brakes applied, take the
line pressure readings in the ranges and at the engine r.p.m.'s indicated in the
chart below.
Full T.V. Line Pressure Check
Full T.V. line pressure readings are obtained by tying or holding the T.V. cable to the full extent of its travel; and with the brakes
applied, take the line pressure readings in the ranges and at the engine r.p.m/s indicated in the chart below.
CAUTION
Brakes must be applied at all times.

Line pressure is basically controlled by pump output and the pressure regulator valve. In addition, line pressure is boosted in Reverse,
Intermediate and Lo by the reverse boost valve.
Also, in the Neutral, Drive and Reverse positions of the selector lever, the line pressure should increase with throttle opening because
of the T.V. system. The T.V. system is controlled by the T.V. cable, the throttle lever and bracket assembly and the T.V. link, as
well as the control valve pump assembly.
