TH350 problem....
My th350 tranny will not come out of low gear, has anyone ever had this problem before?? I pulled the pan, and the small "S" clip had came off and the linkage slipped out of place, so i fixed that and put the pan back on and it still does this... anyone know what the h#$@ is goin on here????

You need a vacuum signal to make the tranny shift. It connects to the vacuum modulator on the passenger side to the tranny.

Is your tranny fluid low? I know the vacuum line is connected but is it connected to a vacuum sorce, so it sees vacuum.
