Does a vacuum line go to the transmission on a 1994 GMC Sonoma

SOURCE: 1998 gmc sonoma push button 4x4 busting diaphram vacuum actuator

On top of the transfer case is a vacuum switch with 3 vacuum lines connected to it. This switch controls when vacuum is applied to the vacuum actuator. This switch can fail partly and allow fluid from the transfer case to be sucked up into the vacuum lines and anything connected to them as well. When you replaced the actuator before, did you notice any oily fluid inside of it?

The PCM for what ?
There are several PCM ( part controle modules) in any given vehicle... Most are integrated in the ECU .

If your transmission is automatic, it probably has a vacuum controlled modulator located on the passenger side near the front of the transmission. It is a round component witha vacuum nipple on it's end and connects to a manifold vacuum source.
