Governor Pressure Test (NA4A-Hl)
- Governor pressure test should only be used if vehicle shift speeds are different than specification. Install adapter and pressure gauge in governor pressure port. See Figure .
- Drive vehicle in "D". Read governor pressure at specified speed. See GOVERNOR PRESSURE SPECIFICATIONS table. If not within specification, clean and repair governor. Repeat test. If still not within specification, replace governor.
