Shanghai BMW X5 automatic transmission repair/Shanghai BMW fault repair

Vehicle Information BMW
Fault phenomenon: When driving above medium speed, the car will vibrate, just like on a speed bump.
Fault Analysis
First, use a computer to detect the data flow and find that this phenomenon occurs when it enters lock-up. Check that the automatic transmission oil turns white to confirm that water has entered, and the transmission needs to be disassembled.
After disassembling the automatic transmission, it was found that the clutch plates swelled due to water ingress, and some began to fall off. After opening the torque converter, it was found that the locking plates had fallen off, which meant that the locking plates had fallen off and caused instability during locking. Because BMW's requirements are relatively high, if lock-up slippage occurs, the computer will control the oil pressure to increase, and will continuously change the oil pressure finger for continuous adjustment, causing vibration.
Troubleshooting, replace repair kit, torque converter, repair and radiator tank troubleshooting.
