I have a 1995 S-10 Pickup w/ a 4.3L V6 type W and the truck's a 2wd. I have an older 4L60E automatic tranny and I noticed there is a place for either a vacuum or breather line on the top of the tranny. Anyone know where that line connects to or if it is a vacuum or breather line? Anyone know where to find any diagrams for vacuum lines for these trucks? I just don't want to ruin the rebuilt tranny by not connecting this hose to it. Thanks.
