Dumb Question.
 

I am going to replace the brake vacuum modulator on my TH400 Suburban soon.

My dumb question is: when I remove the valve, will transmission fluid come out?

Thanks.

You're talking about the vacuum modulator on the passenger side of the transmission that connects to the back of the intake manifold? If so then only a little with dribble out but it won't come pouring out.
