OIL PRESSURE CHECK PROCEDURE
PRELIMINARY CHECK PROCEDURE
* CHECK TRANSMISSION OIL LEVEL
* CHECK AND ADJUST T.V. CABLE
* CHECK OUTSIDE MANUAL LINKAGE
* CHECK ENGINE TUNE
* INSTALL 0-300 PSI PRESSURE GAUGE
* CONNECT TACHOMETER TO ENGINE
* CHECK OIL PRESSURE AS FOLLOWS
MINIMUM T.V. LINE PRESSURE CHECK:
With the T.V. Cable properly adjusted and the brakes
applied, take the Line Pressure readings in the Ranges
and at the engine RPM’s indicated in the chart.
FULL T.V. LINE PRESSURE CHECK:
Full T.V. Line Pressure readings are obtained by holding the T.V. Cable to the full extent of it’s travel then take the
Line Pressure readings in the Ranges and at the engine RPM’s indicated in the chart.
CAUTION: Limit running time at FULL T.V. Pressure to two (2) minutes maximum to prevent overheating.
CAUTION: Brakes should be applied at all times.

NOTE: Oil Pressure at FULL T.V. Pressure depends on the particular T.V. Boost valve and Line Bias Valve
arrangement of the unit. The Pressure reading obtained should be within the range shown.
Base Line Pressure is controlled by the Pressure Regulator Valve and Spring. Line Pressure is boosted a fixed
amount by the Reverse Boost valve when the selector lever is placed in Second or Low Range. The Line Pressure
is also boosted in Neutral, Drive, Drive3 and Reverse with throttle opening because of the T.V. system. The
pressure is controlled by the T.V. Cable via the throttle Lever and Bracket assembly to the Valve Body assembly.
The Line Pressure tap is located on the left side of the transmission case above the outside Manual Lever.
