When kicking the automatic transmission in a Toyota Corona, you must perform the following steps:
1. Check the level and condition of the ATF fluid: Low level or dirty fluid can cause automatic transmission malfunctions. Check the fluid level and replace it if possible.
2. Check the condition of the automatic transmission sensors: Faulty sensors can transmit incorrect data to the automatic transmission, which leads to kicking. Check the input and output speed sensors, ATF temperature sensor, and throttle position sensor.
3. Check the condition of the automatic transmission solenoids: The solenoids control gear shifting. Faulty solenoids can cause jerking. Check the solenoids and replace them if necessary.
4. Check the torque converter: The torque converter connects the engine to the transmission. A faulty torque converter can cause kicking. Check its level and condition of the fluid, as well as any signs of grinding.
5. Check the condition of the automatic transmission clutches: The clutches transmit power between the automatic transmission components. Worn or dirty clutches can cause slipping and kicking. Check the condition of the clutches and replace them if necessary.
6. Check the condition of the automatic transmission: If all other checks have not revealed any malfunctions, you may need to inspect the automatic transmission itself. Check for damage, leaks or signs of wear.
If you are not confident in your abilities, it is recommended that you contact a qualified mechanic to diagnose and repair the automatic transmission.
