Automatic transmission gas draft adjustment

In order to quickly achieve the desired acceleration, for example, in the process of overtaking, the automatic transmission has a so-called accelerator switch, which is activated when the gas pedal is fully depressed. The automatic transmission control unit ensures that the gearbox either stays in direct gear longer or shifts from a higher gear to a lower one. A prerequisite for the functioning of the accelerator switch is the correct adjustment of the throttle thrust.

Adjustment

Clamp a board 15 mm thick between the gas pedal and the pedal stop. Lock the pedal in this position.



By pulling at the rod sheath -1-, fully open the throttle valve and by moving the locking clip -2- at the counter-support, adjust it in this position.

Release the gas pedal.



Disconnect the plug from the accelerator switch and connect a digital multimeter to both contacts of the plug block. The switch is located at the rear wall of the engine compartment next to the gas draft.

Measure resistance. The prescribed value is ∞ (infinity) Ohm.

Slowly press the gas pedal in the direction of increasing load and at the same time observe the reading of the multimeter. Immediately after the moment the accelerator switch is activated, the resistance should drop to 0 ohms. In this case, the gas pedal should be almost in front of the stop.

Otherwise, repeat the adjustment.
