sorry, Still workin on my Signature, It is a 97 12 valve 4x4 extra cab long bed, auto 4:10 differentials, but i just would like to know as right now my transmission is out, and truck will not even start to crank when turn key, and the od button and the trans emp light is on, so im guessing once i plug in the sensors to the appropriate wires they will either 1 go back to normal or 2 have to do a "reflash"? im not sure So what do others do once they have put the transmittion back in? any help would be gladly appriciated thnx Regards
