Went to get in my truck when I got off work today and it would not shift out of second, manually or leaving it in drive. Fluid is good, it has a mod. valve and by-pass electrics, no it is getting plenty of vac. It is teed off of brake booster hose coming straight off of intake. It has been shifting fine and have no problems. Do u think maybe the vac. module went bad? I thought that if it did u would still be able to manually shift it? Any help would be greatly appreicated.
