Possible causes and their elimination:
1. Low transmission fluid (ATF):
* Check the ATF level with the transmission warm.
*Add ATF to the correct level according to the gauge or dipstick.
2. Contaminated ATF:
* Replace ATF and transmission filter according to the specified schedule.
3. Wear of friction discs:
*This is a common sign of transmission wear.
* The only solution is to repair or replace the transmission.
4. Torque converter damage:
* The torque converter transfers power from the engine to the transmission.
* If it is damaged, it may cause slipping.
*The torque converter may need to be repaired or replaced.
5. Faulty solenoids:
* Solenoids control the flow of ATF in the transmission.
* Their malfunction can lead to incorrect gear shifting and slipping.
*Faulty solenoids may need to be replaced.
6. Mechanical problems:
* Worn or damaged gears, bearings or other components can cause slippage.
*Internal components may need to be repaired or replaced.
7. Software problems:
*Some transmissions are controlled by electronic modules that may fail or require reprogramming.
*Diagnosis and repair or reprogramming of the electronic module may be required.
Tips for further actions:
*Check ATF Level: Do this first, as this is the most common cause of slippage.
*Consult Auto Service: If the problem is not related to the ATF level, take it to a qualified mechanic for diagnosis and repair.
* Don’t delay repairs: Slipping can lead to more serious damage and costly repairs.
