One hose is connected to engine vacuum, one hose goes to the front diff actuator on pass front fender area under battery and the other hose is just a vent

When 4x4 is engaged, there is transmission fluid being drawn into the engine via vacuum. Is this a vacuum actuator problem or another booger.

Could be the vacuum switch on the transfer case.Have any of the vacuum lines been moved or any work done on it? If the vent line is put on the engine it can do that.If nothing has been changed recently, it is most likely the vacuum switch on the transfer case.
