Do you mean ther's inside another regulation point? |
A Vacuum Control Valve (VCV) is used
ONLY with Diesel engine vacuum pumps.
Petrol engines
DO NOT have a VCV.
What you have circled in red is a Vacuum
MODULATOR.
In Post #5 it was explained that the shift points are controlled by the Control Pressure Valve, which is operated by the Control Pressure Lever at the right front of the transmission.
When the transmission hydraulic pressure is changed by adjusting the Vacuum Modulator, there will also be a change in the shift points. However, the shift points can then be corrected by adjusting the Control Pressure. That is done by changing the length of the rod from the throttle to the Control Pressure Lever. This was also explained in Post #5.
