No, it definitely does not.

The supply vacuum must have a restrictor in the line.......before the VCV. This limits the amount of air that can pass through the restrictor. So, the VCV can then provide a controlled bleed to drop the vacuum to the transmission depending on throttle position. It certainly cannot control vacuum if the supply is unrestricted.

So, check carefully to see if you have this restrictor. It's nothing more than a plastic connector with two vacuum nipples protruding from either side. You can easily miss it in the line if you don't look carefully. Just look for a very narrow piece of plastic right in the middle of the vacuum line to the VCV. That's the restrictor.

If you don't have the restrictor, the system can't function as designed.
