TC Prop Valve Specs... December 19, 2011, 02:54:55 AM First post! I looked for an intro section but didn't see one... Anyway...Does anyone have a factory shop manual for a 87 or 88 TC that they could look up the proportoning valve specs in?What I was looking for is split and slope and I believe it also lists the port sizes there too.Thanks in advance... SteveBTW, killer site guys!!! The tech is awesome! I've been reading for quite awhile tonight!!!:burnout: Quote Selected
