Checking the operation of the automatic transmission
1. Checking fluid levels:
* Check the automatic transmission fluid level with the engine running and park gear engaged.
* Make sure the level is between the “cold” and “hot” marks on the dipstick.
* The liquid should be red or pink.
2. Gear shift check:
* Move the gear shift lever to all positions and check whether the shift occurs smoothly.
* Pay attention to vibrations, slipping or jerking.
3. Checking slippage:
* Find a flat surface and accelerate the car to a speed of about 50-60 km/h.
* Press the gas pedal sharply and observe whether the gearbox slips.
4. Checking for errors:
* Connect a diagnostic scanner to the vehicle and check for fault codes.
*These codes may indicate problems with the transmission or other components associated with it.
5. Appearance check:
* Inspect the transmission for leaks, damage or corrosion.
* Make sure all electrical connectors are securely connected.
6. Checking the operation of solenoids:
* Solenoids control gear shifting.
* Try resetting the transmission adaptation to clear the solenoid memory.
*Follow manufacturer’s instructions for your specific vehicle model.
7. Checking the torque converter:
* The torque converter is used to transmit torque from the engine to the gearbox.
* Check for vibration or noise when shifting gears.
Other tips:
* Change the automatic transmission fluid and filter regularly in accordance with the manufacturer’s recommendations.
* Avoid aggressive driving which may damage the transmission.
*If you notice any problems with the automatic transmission, contact a transmission repair specialist.
