Possible reasons for jerking of the Toyota Camry automatic transmission:
1. Wear or contamination of transmission fluid (ATF)
*Old or dirty fluid can cause low system pressure, which can cause the transmission to slip and jerk.
* It is recommended to change the ATF according to the maintenance schedule or more frequently under severe operating conditions.
2. Malfunction of transmission solenoids
* Solenoids control the flow of fluid in the transmission and can wear out over time.
* A faulty solenoid can result in incorrect gear changes or jerking.
3. Wear of friction discs
* Friction discs mesh the gears with each other.
* Worn discs can cause slipping and jerking when shifting.
4. Torque converter malfunction
* The torque converter ensures smooth gear transitions.
* A malfunctioning torque converter may cause vibration or jerking during acceleration.
5. Problems with the throttle position sensor
* The throttle position sensor tells the engine control unit about the position of the gas pedal.
*A faulty sensor can give the transmission incorrect signals, which can cause it to jerk.
6. Electrical problems
* Faulty wiring or connections in the transmission control system can cause roughness and jerking.
* Check electrical connections for corrosion, damage or looseness.
Diagnostics and repair:
To diagnose Toyota Camry transmission jerking, you must:
* Checking ATF level and condition
* Scan fault codes
* Checking the gearbox solenoids
* Checking friction discs
* Diagnosis of torque converter
* Checking the throttle position sensor
* Checking electrical connections
Once the diagnosis is made, appropriate repairs must be made, such as:
* Replacing ATF and filter
* Replacement of faulty solenoids
* Replacement of friction discs
* Repair or replacement of torque converter
* Replacing the throttle position sensor
* Repair or replacement of electrical connections
