    Who has a TBI with a TH350?
    Which vaccum port on the throttle body did you use for the trans?? Or did you take it off of the manifold? Thanks :)

    I dont have that set up but I would use manifold vaccum. Most of the ports on the TB are for sensors. If the Vac modulator goes bad and leaks you wouldn't want to risk getting trans fluid in a map sensor or something.

    Hmmm..good point! I wanted to use a port for ease and tidyness but I see what you're saying.

    it goes on the manifold in the back side of the tbi unit. not on the tbi. had this setup in my old dd truck worked good. then i missed my od and went to a 4l80 setup.

    Thanks, I've got a take off for that outlet so I'll stick it there. My DD has a 700r4 and I think I'm really going to miss the overdrive so I'm keeping an eye out for a 700. One may turn up one day! :)

    Just put it in a big bottle and toss it in when the tide is going out.
