The VCV on the MRSF pump works together with a switchover valve. The switchover valve is responsible for the shiftback to first gear upon take-off.

Here is the vacuum scheme:



And here is how to hook up your VCV:



If you don't have a switchover valve, you can connect the transmission straight to the VCV.

On the side there is a vent line, connect a vacuum line to it and let it vent from the interior, stick the vacuum line into the interior.

The VCV can be adjusted: loosen the two bolts of the VCV, put the IP in full load with your hands, turn the VCV until you feel resistance, whilst keeping the pump in full load. Tighten bolts.
