Governor Pressure Test
- Transaxle must be at normal operating temperature of 122-176°F (50-80°C). Block rear wheels. DO NOT
apply parking brake. Raise and support front of vehicle with safety stands.
- Remove appropriate transaxle plug and connect pressure gauge. See Figure. Start engine and shift vehicle into "D" position. Note governor pressure at specified speeds and engine RPM. See GOVERNOR PRESSURE SPECIFICATIONS . Readings at 490 and 800 RPM can be taken with vehicle on safety stands.
CAUTION:
Road test vehicle or use chassis dynamometer to check governor pressures at vehicle speeds above 800 RPM.
- Incorrect governor pressure may be caused by incorrect line pressure, leakage at governor pressure circuit or defective governor valve.
