Possible automatic transmission problems causing vibration:
Torque converter
* A faulty or worn torque converter can transmit vibration to the engine and transmission.
Clutch packs
* Worn or coked clutch packs can cause slipping, jerking and vibration when shifting.
Planetary gears
* Worn planetary gears or their bearings can create vibration, especially when driving in low gears.
Hydraulic block
* A faulty or clogged hydraulic unit can interfere with the pressure supply to the clutch packs and bands, resulting in vibration.
Drive shaft
* An unbalanced or bent drive shaft can create vibration that is transmitted to the transmission housing.
Differential
*A faulty or worn differential can cause vibration, especially when cornering or accelerating.
Reason for vibration
To determine the specific cause of the vibration, the transmission must be diagnosed by a trained mechanic. They can use a trouble code scanner, inspect the transmission fluid, and perform a test drive.
Solutions
Repairing automatic transmission problems that cause vibration may include:
* Replacing the torque converter
* Repair or replacement of clutch packs
* Replacement or overhaul of planetary gears
* Flushing or replacing the hydraulic unit
* Balancing or replacing the drive shaft
* Repair or replace differential
It is important to seek help from a qualified mechanic if you experience automatic transmission vibration, as it may indicate a serious problem that could lead to costly repairs.
