Ok fellas heres the deal this tranny has 70.000 miles on it and not always but at times when it down shifts from 2 to1 it clunks how normal is this. It shifts fine just every once and again on the downshift i get a clunk like you feel it down shift.Played with the tps set it dead on, high, low same deal not always but its definatly in that downshift . Please give me some input do they all do it ocaisionally any help would be apprieceated thanks Richie. Ps tranny has a banks command on it i bypassed it thinking maybe line pressure is to high and same deal

I'm not sure about the tranny, but the first thing I would check is the drive shaft.
