Going back to your first post I see you said someone added a part throttle kickdown. Did they use the old Direct connection part throttle conversion kit or did they just bolt on a part throttle module from a newer VB? I haven't tried it but from everything I've read you can't just bolt a part throttle module onto a older valve body and it work. Maybe someone else here has some input on it. If not I'd take the part throttle module off and look real close at things to see if it looks right.

One other thing. What year is this trans?
