HYDRAULIC PRESSURE TESTS
Line Pressure Test
NOTE:
Hydraulic pressure tests should be performed with transmission fluid temperature at normal operating temperature of 122-176°F (50-80°C).
1. Ensure transmission fluid is at normal operating temperature. Connect Pressure
Gauge (09992-00094) to line pressure test port on transmission. See Fig. 8.
2. Connect tachometer to vehicle and ensure it is visible to driver. Block all 4 wheels and fully apply parking brake. Start engine and ensure idle speed is adjusted to specification.
3. Apply service brake and shift transmission to "D" position. Check line pressure
at idle and record pressure reading. Accelerate vehicle to stall speed and record
line pressure reading.
4. Repeat test procedure in "R" position. If line pressures are not as specified, check
throttle cable adjustment. Adjust throttle cable (if necessary), and repeat test procedure and record pressure readings. Compare all readings to specification.
Refer to the appropriate table under LINE PRESSURE SPECIFICATIONS.
