Possible causes of vibration in the automatic transmission:
Transmission fluid problems:
*Low fluid level
* Poor fluid condition (dirty or old)
* Wrong brand or type of fluid
Transmission component failure:
* Worn clutch clutches

Cardan shaft malfunction:
* Imbalance or deformation
* Faulty bearings or joints
Engine or transmission problems:
* Unstable engine speed
* Ignition system malfunctions

Diagnostic steps:
1. Check the transmission fluid level: Measure the fluid level on the dipstick while the engine is running and warm.
2. Inspect the transmission fluid: Remove a sample of the fluid and inspect it for signs of contamination, darkening, or a burning odor.
3. Scan the vehicle for trouble codes: Connect the OBD2 scanner to the vehicle’s diagnostic connector and check for transmission or engine related codes.
4. Perform a visual inspection: Inspect the transmission, driveshaft, and mountings for signs of leaks, damage, or deformation.
Possible solutions:
*Add or replace transmission fluid
* Replace faulty transmission components
* Balance or replace driveshaft
* Troubleshoot engine or transmission problems
* Tighten loose fasteners
Important: If you experience vibration in the automatic transmission, it is recommended that you contact a qualified mechanic for diagnosis and repair as soon as possible. Delaying repairs can lead to further damage and costly repairs.
