A transmission fluid pressure test is performed to determine the condition of the hydraulic components and whether there are any leaks.
Execution order
1. Start the engine until the gearbox warms up to a temperature of 60~70°C.
2. Raise the front of the vehicle so that the drive wheels can turn freely.
3. Connect the tachometer and position it so that it is clearly visible.
4. Connect special pressure gauge 09452–21500 with adapter 09452–21002 to each pressure test nipple.
To check the back pressure, it is necessary to use a pressure gauge with a measurement limit of 3,000 kPa.
5. Measure the transmission fluid pressure at various selector lever positions and engine speeds. If the pressure does not correspond to the required values, check and repair the transmission components.
