Adaptation of Toyota RAV4 automatic transmission
Automatic transmission (AT) adaptation is the process of calibrating its electronic controls for optimal gear shifting and improved performance. In Toyota RAV4 cars, automatic transmission adaptation may be required after replacing the transmission fluid, automatic transmission sensors or electronic control unit (ECU).
Adaptation process
1. Place the gear shift lever in Park (P) position.
2. Start the engine and let it idle for 5 minutes.
3. Shift the gearshift lever to position D (Drive) and keep the brake pedal depressed.
4. Press the accelerator pedal and hold the engine speed at 2500 rpm for 10 seconds.
5. Release the accelerator pedal and let the engine speed drop to idle.
6. Repeat steps 4 and 5 3 more times.
7. Shift the gearshift lever to N (neutral) and let the engine idle for 1 minute.
8. Stop the engine.
9. Start the engine again and shift into gear D.
10. Check gear shifting under moderate acceleration and deceleration.
Note:
* The time required to complete the adaptation may range from 5 to 10 minutes depending on the model and year of the vehicle.
*If adaptation does not complete successfully, it may be necessary to contact a qualified mechanic.
* Regular adaptation of the automatic transmission can help optimize its performance and extend its service life.
