Steps to eliminate kicking in an automatic transmission:
1. Check the transmission fluid level: Low fluid levels can cause slipping and kicking. Check the fluid on the dipstick with the engine running and the transmission in the ‘park’ position.
2. Replace transmission fluid and filter: Old or contaminated fluid can cause friction and kicking. It is recommended to replace the fluid and filter according to the manufacturer’s recommendations.
3. Check spark plugs and wires: A faulty ignition system can cause misfires that lead to kicking. Replace faulty components.
4. Clean the throttle position sensor: A dirty sensor can send incorrect signals to the engine, resulting in gear shifts at inopportune times. Clean the sensor with electrical contact cleaner.
5. Check Speed Sensor: A faulty speed sensor may send incorrect vehicle speed information to the transmission. Replace the faulty sensor.
6. Scan your computer for trouble codes: The car’s computer may store trouble codes that can help determine the cause of the kicking noise. Connect the OBDII scanner to the car and read the codes.
7. Adjust Shift Cables: Incorrect adjustment can cause delayed or harsh shifts. Adjust the cables according to the manufacturer’s specifications.
8. Check the torque converter: The torque converter transfers power from the engine to the transmission. A faulty torque converter can cause vibration and kicking. Replace it if necessary.
9. Rebuild the automatic transmission: In some cases, it may be necessary to rebuild the automatic transmission to eliminate kicking. This is a complex process that must be performed by a qualified mechanic.
If none of these steps resolve the kicking, contact a qualified mechanic for further diagnosis and repair.
