问：汽车启动n个闲置。当我把它放在齿轮上时。我在想传输流体问题吗？它也会在移动时“抓”

应评估扭矩转换器和扭矩转换器锁定电磁阀。另一种可能性是传输密封中的内部液压泄漏，导致压力同时施加反向和前进齿轮，锁定变速箱并拖延发动机。压力测试（外部测量值）可用于查看此类泄漏是由密封泄漏或泄漏的反向或向前的电磁阀/阀引起的。

Another possibility relates to engine controls. Test the throttle position sensor, idle control valve as well as the manifold absolute pressure (MAP) sensor. The MAP sensor detects engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The ECU uses this information to adjust ignition timing and fuel enrichment relative to the amount of power needed. When the engine is working hard, intake vacuum drops as the throttle opens wide and the engine takes in more air, which requires more fuel to keep the air/fuel ratio in balance. When the computer reads a heavy load signal from the MAP sensor, it adjusts the fuel mixture to slightly more rich than normal so the engine can produce more power. The computer will then retard (back off) ignition timing slightly to prevent detonation (spark knock) that can damage the engine and decrease performance. If the MAP sensor is faulty, this foregoing sequence may explain why the engine dies as you put the vehicle into gear as a load is put on the motor.
