Possible causes and solutions
1. Problems with automatic transmission oil
*Low oil level: Make sure the automatic transmission oil level meets manufacturer specifications. Add oil if necessary.
* Old or contaminated oil: Change the automatic transmission oil regularly according to the manufacturer’s recommendations. Old or dirty oil can cause internal components to seize and cause vibrations.
2. Problems with mechanical components of the automatic transmission
* Worn or damaged friction plates: Clutch plates transfer power from the engine to the transmission. Wear or damage can cause slipping and jolting.
* Damaged torque converter: The torque converter connects the engine to the transmission. Damage may result in uneven power delivery and jerking.
* Sticky solenoids: Solenoids control the flow of oil into the automatic transmission. Sticking can cause delayed or slipping shifts.
3. Problems with automatic transmission electrical equipment
* Faulty speed sensor: The speed sensor transmits information about the speed of the vehicle to the automatic transmission. A faulty sensor can result in incorrect gear shifting and jerking.
* Damaged automatic transmission control unit (TCU): The TCU controls the operation of the automatic transmission. Damage can impair transmission operation and cause vibrations.
* Wiring Problems: Damaged or corroded wiring can disrupt the signal between the TCU and the transmission.
4. Engine problems
* Misfire: Unburned air-fuel in the combustion chamber can be transferred to the exhaust system, causing engine vibration. These vibrations can be transmitted to the transmission, causing jolts.
* Reduced Power: Reduced engine power (for example, due to fuel or ignition problems) can affect gear shifting, causing jerking.
Solving the problem
1. Check the level and condition of the automatic transmission oil.
2. Use a diagnostic scanner to identify trouble codes related to the automatic transmission.
3. Contact an experienced mechanic ???? ????? and eliminating mechanical or electrical problems with automatic transmissions.
4. Make sure the engine is running properly.
5. If the problem persists, consider overhauling or replacing the automatic transmission.
