Cable-operated gas drive on cars with automatic transmission (VW Transporter T3)

The throttle drive should be adjusted so that when the throttle valve is closed (idling) the actuator lever on the gearbox was on the stop in the zero gas position. Otherwise, switching to higher gears at medium speeds will occur with a delay.

Adjustment of the gas cable drive is made in the idle position (engine warmed up: throttle valve closed, choke fully open) as follows:



Unscrew nut "1".

Remove spring "2".

Pull the throttle rod in the direction of the arrow (zero throttle position).

Using a screwdriver, adjust the end switch "3" so that the end switch surface fits against the drive axle pin.

Install spring "2". Start the engine and make sure it operates at the specified idle speed. If necessary, adjust by turning limit switch "3".

Lock the end switch with nut "1".

Press the gas pedal all the way down. The gearbox actuator lever should be positioned on the stop in the Kickdown position "arrow A".

Release the gas pedal. The gearbox actuator lever should be set on the stop in the zero gas position "arrow B".



If necessary, adjust the throttle cable adjustment with the clamp bolt.

Checking the adjustment

Press the gas pedal to the full throttle point. The gearbox actuator lever should be positioned on the stop (no Kickdown).

The gearbox actuator lever must be installed on the stop in the Kickdown position.
