Look underneath on the transmission.It screws in and usually has a round head on it.2-3 times bigger than a spark plug and a vacuum hose attached to it.Just pull the hose lose and unscrew it with visegrips or suitable tool.A repair manual will show you exactly.

Dude, there isn't a modulator on a Chev truck of that era. And if it had a turbo 400, the mod is held in by a little bracket. I am sure you have a 4L60E however. Dan the tranny man
