Hi Clipbee, If you have the pan off and have disconnected the control valve it should be possible to move it but remember that it has a serrated end held between two sets of spring loaded balls, so it will only move with considerable force ( say 40 lbs), between each gear selection serration. If the trans was full of fluid then it is unlikely that the control valve is jammed. There is also a possibility thet the control relays for the PB have been incorrectly wired. I would hasten slowly and be guided by Mr PB on that aspect. Best Regards Peter Toet
