Signs of automatic transmission slipping:
When accelerating:
* The car accelerates slowly despite pressing the gas pedal deeply.
* Engine speed increases sharply without a corresponding increase in vehicle speed.
* There is a slipping sound or vibration coming from the transmission.
When changing gears:
* The transmission shifts jerkily or with a delay.
* Slipping or knocking noises occur when shifting gears.
* The automatic transmission fault indicator lights up on the instrument panel.
When driving at low speed:
* The vehicle vibrates or sways when driving slowly or when stopped.
* There is a noise or humming noise coming from the transmission.
Other signs:
* Change in color of automatic transmission fluid (becomes darker or contains metal particles).
* Increased fuel consumption.
* Burning or smoke smell from transmission.
Checking automatic transmission slipping:
1. Checking the level and condition of the automatic transmission fluid: Make sure that the fluid level is correct and that it is not darkened or does not contain metal particles.
2. Visual Inspection: Check the transmission for leaks or damage.
3. Slip Test: Accelerate on a flat surface and observe the engine RPM and vehicle speed. If the RPM increases suddenly without a corresponding increase in speed, this may indicate slipping.
4. Shift Test: Accelerate and shift gears at different speeds. Pay attention to smooth shifting and any slipping or knocking noises.
If you notice any of the listed signs, it is recommended to contact a car service as soon as possible for diagnosis and repair. A slipping automatic transmission can cause serious damage to the transmission.
