Possible causes of automatic transmission vibration when accelerating:
1. Low gearbox fluid level:
* Insufficient fluid can cause the clutch to slip, resulting in vibration.
* Check the fluid level and add if necessary.
2. Problems with the torque converter:
* The torque converter connects the engine to the transmission and transmits torque.
*A faulty torque converter can cause vibration at certain speeds.
3. Clutch malfunction:
* Worn or faulty clutches in the transmission may slip, causing vibration.
* Requires diagnostics and replacement of clutches if necessary.
4. Shaft problems:
* Misalignment or damage to the shafts in the transmission can cause vibration.
* It is necessary to correct the alignment or replace damaged shafts.
5. Worn bearings:
* Worn or faulty bearings can cause vibration and noise in the transmission.
* Worn bearings need to be replaced.
6. Sensor malfunction:
*Speed or position sensors may provide incorrect readings, resulting in transmission malfunction and vibration.
* Faulty sensors must be checked and replaced.
7. Problems with differential:
* The differential distributes power between the drive wheels.
*A faulty differential may cause vibration when accelerating.
8. Worn drive shafts:
*Worn or damaged drive shafts can cause vibration when transmitting power to the wheels.
* Worn drive shafts need to be replaced.
9. Malfunction of the electronic control unit:
* The Electronic Control Unit (ECU) controls the transmission.
* A faulty ECU may cause the transmission to malfunction and cause vibration.
What to do:
* Check the fluid level in the gearbox.
*Consult a qualified mechanic to diagnose and repair the problem.
*Do not ignore vibration as it may cause more serious damage to the transmission.
