I took the truck to a tranny shop and he put it on some kind of scanner and said I had a code for the defective manifold pressure switch which he said was in the transmission and could cause my symptoms. Im thinking this is the pressure switch assembly that bolts to the valve body tells the computer what gear it is in. do know that when I was replacing the o'rings on the face of the switch I inadvertantly removed the plastic film with one of the o'rings and just put it back on with the new o'ring. Could this be my problem?
