Thread: 400 won't shift

Tweet

ok, i hooked the trans up to the big vacuum port on the front of the carb and the trans shifted flawlessly. the distributor is hooked to the small ported vacuum on the front of the carb. does the pcv valve connect to the big port on the front of the carb. i tested it for vacuum and there was none. right now the pcv is teed w/ the brake booster directly into the intake manifold, thanx, rick

Pcv should be OK...It runs off manifold vacuum as well...Glad the trans worked out for you Advance runs off port Vacuum so that's correct too
