Thanks for the info. I suspect that this may be a vacuum related problem, i.e., not enough somehow.

The tranie was hooked to a cast aluminum "T" fitting on the original manifold which snapped off when removing. I plugged that hole in the new (Performer) mainfold and optied to use vacuum hose to hook up the trannie at the front of the carb. Maybe I should procure another fitting to get the trannie vacuum back to the original configuration.
