To review the advice I have been given above:
1. Poster Guitplayer asks why I am whining now after having reported that I am happy with my installation. Answer: I am still very happy with my overdrive operation. I call this shifting problem a separate issue not related to the overdrive unit.
Ok, never realized you were whining. You reported ALL is well. I guess not. If you put the disc in backwards then I`d check it all.
