Selector Group (1) Relief valve for the transmission oil pump (2) SpacersThis test will determine the following condition:
The transmission oil pump is good.
The relief valve for the transmission oil pump (1) is set correctly.Procedure

Left Side of Transmission (3) Pressure tap for transmission pump
Remove the dust cap at pressure tap (3). Then connect 198-4240 Digital Pressure Indicator to pressure tap (3) .
While the parking brakes are engaged, start the engine and operate the engine at LOW IDLE rpm. The transmission should be in NEUTRAL. The pressure on the gauge should read a minimum of 2700 kPa (390 psi).
Operate the engine at HIGH IDLE rpm with the transmission in NEUTRAL. The pressure on the gauge should read a maximum of 3300 kPa (480 psi).
When this test is complete, stop the engine. Remove the test equipment.Results

The transmission oil pump has failed.
The setting of the relief valve for the transmission oil pump (1) is too low. Add spacers (2). Refer to Table 2. Adjust for LOW IDLE engine setting.If the oil pressure is too high, the following conditions occurred:
Setting of the relief valve for the transmission oil pump (1) is too high.
Remove spacers (2). Refer to Table 2. Adjust for LOW IDLE engine setting.
