Vibration when braking caused by an automatic transmission can be the result of several possible problems:
1. Torque converter malfunction:
* Torque is generated and transmitted to the transmission
*A faulty torque converter can cause vibration due to imbalance or broken internal components
2. Gearbox malfunction:
*Gears, bearings and other transmission components can wear out over time
*Worn or faulty components may cause vibration during torque transmission
3. Drive fault:
* Drive shafts and CV joints (constant velocity joints) transmit torque from the gearbox to the wheels
*Worn or damaged drives may also cause vibration
4. Problem with the brake system:
*Faulty brake pads or rotors may cause vibration when braking force is applied
* Warped or worn brake components can cause uneven braking, which causes vibration
5. Other reasons:
* Unbalanced wheels
*Worn or damaged tires
* Faulty wheel bearings
Diagnostics and repair:
To diagnose vibration during braking caused by an automatic transmission, it is necessary to conduct a thorough inspection of the vehicle:
* Check the brake system for faulty or worn components
* Carry out automatic transmission diagnostics using a fault code scanner
* Inspect drives and shafts for signs of damage or wear
*If the problem cannot be identified visually, more advanced diagnostics may be required, such as checking the torque converter or transmission.
Repairs will depend on the cause of the vibration. It usually involves replacing faulty components such as the torque converter, gears or drive shafts. In some cases, major repairs or replacement of the entire automatic transmission may be required.
