What type of modulator line is used on a T-350 trans in our trucks, is it a metal line or rubber line? Thanks.

Metal line connected at the ends with rubber hose.

Runs from a vacuum fitting on the intake (just in front of the dizzy) to the modulator on the pass. rear side of the transmission. Uses vacuum to shift the transmission out. If it is not connected the tranny will have only shift out manually.

Hey...thanks Krue. I have one, but it is all rubber. Guess I will order a stailess steel one from Inline Tube, since I just got my cooler lines from there. Thanks.
