Alright so I traded for this 2002 Silverado 1500 4x4 an the trans was already half way out an so I finished it up an put it back together an now the speedos not working an the trans won’t shift out of first I’ve changed the sensor which obviously changed nothing since there was no power but I’ve checked all the wires fuses an changed relays what else could it be? Someone help me before I part this thing out.

 

Changed the sensor, try another one, yes I know they are about 30 bucks, get one from a salvage.
