snoking,thank you for your reply. i have my 47 rh out trying to repair some parts i'am having trouble finding. i had a lead on 47re but i won't pursue this. i also changed the rear crank seal i started the motor and let it run for an hour every thing was o.k. all the wires from pcm were unplugged with the exception of the trans temp. gauge, would this damage the pcm?
