Check in motion
* Check the smoothness of gear shifting: Gears should shift smoothly, without jerking or slipping.
* Pay attention to vibration and noise: There should be no noticeable vibration or noise when shifting gears.
* Check engine braking: When you release the accelerator pedal, the vehicle should be braking with the engine, without going into neutral or slipping.
* Test the kickdown mode: Press the accelerator pedal to the floor to test the kickdown mode, which should result in a downshift for acceleration.
Checking in a static position
* Check the transmission fluid level: The level should be within the normal range indicated on the dipstick. The liquid should be clean, without signs of cloudiness or a burning smell.
* Check the condition of the gear shift cable: The cable must be in working order, without binding or damage.
* Check the electrical wiring: Check the connectors and wires leading to the automatic transmission for damage or corrosion.
Other signs
*Transmission Fluid Leaking: Transmission fluid leaks can indicate seal problems or oil leaks.
* Burning smell: A burning smell may indicate overheating or wear of the automatic transmission.
* Automatic Transmission Malfunction Indicator: Many vehicles have an automatic transmission malfunction indicator that lights up when problems are detected with the transmission.
Additional Tips
*If you are unsure about the operation of the automatic transmission, contact a qualified mechanic.
* Maintain your automatic transmission regularly to prevent problems and extend its service life.
* Avoid towing heavy loads or sudden acceleration, which could damage the automatic transmission.
