What does it mean when the full transmission power cannot be obtained?

When the full transmission power cannot be obtained, it means there is a cylinder misfire in the engine, which requires timely inspection and repair. The specific causes of intermittent cylinder misfires in the engine are as follows: 1. Ignition system: Aging of the ignition coil and spark plugs can cause the ignition system of the cylinder to fail. Problems with the ignition coil are most likely to result in a drop in power, and in severe cases, can lead to sudden engine stalling. 2. Fuel injection system: Clogged fuel injectors or fuel lines can prevent the cylinder from receiving sufficient fuel for combustion, naturally causing the cylinder to malfunction. 3. Excessive carbon buildup on spark plugs: Long-term poor combustion leads to carbon deposits accumulating at the spark plug ignition point. When these deposits are wetted by fuel, they create a parallel shunt resistance, resulting in spark plug leakage, weak sparking, or even complete spark plug failure.
I've worked in a repair shop for over a decade and encountered many car owners whose dashboards displayed the 'unable to obtain full transmission power' warning. In about 80% of cases, this indicates a problem with the drivetrain system where the engine's power can't be fully transmitted to the wheels. Common causes include sensor failures, transmission computer malfunctions, or turbocharger air leaks. Last month, I fixed a BMW where a faulty oil pressure sensor caused the car to automatically reduce power to protect the transmission. If you see this warning, immediately read the trouble codes and avoid driving on highways. A sudden loss of power could be dangerous. During repairs, always check both electrical circuits and mechanical wear conditions.
That day during a long drive, I suddenly saw this warning pop up on the dashboard, and I was completely stunned. The car obviously had no power, and even with the accelerator pedal floored, the speed wouldn't go up. I called a friend at the 4S store, and he told me not to panic, saying the transmission system had entered protection mode. Later, after inspection, it was found that the transmission oil temperature sensor had given a false alarm, and clearing the fault code fixed it. He told me that if the turbocharger pipe leaks air, it could also cause this issue because the engine wouldn't receive the correct pressure signal. Now, every time I go for maintenance, I have them focus on checking the oil pipes and wiring connectors of the transmission system to prevent problems before they occur. The earlier such issues are addressed, the more money you save—never delay.
