What is the reason why there is no oil when the automatic transmission is in auto start?

When idling, there is no oil, so the automatic gear cannot work. First, the throttle may be too dirty. Check the clean throttle (the throttle signal is the main control signal of the gearbox); Second, check whether the gearbox is too dirty and increase the transmission resistance. How often the throttle is cleaned depends on the use of the car. It can be cleaned after driving for 20,000 to 30,000 kilometers.

The function of automobile throttle

There will be problems if the force of traffic jam blocks the throttle. The key point is that air enters the engine, so that gasoline and air can be fully combined for combustion. Whether the throttle valve is clean or not directly determines the accuracy and smoothness of engine intake.

If the throttle valve is not clean, it will cause engine idling jitter and flameout; The car always nods when driving, and the fuel consumption increases a lot. The most important thing is that it will damage the engine or even stop working.
