I own a 92 4.3 1500. its the opt. 4 speed auto RWD and not much of anything but a work truck. In 92 GM had a DRAC mod put in these trucks that i believe regulates gear ratio or something like that. Anyways i need to replace this and its dead tech. I tried the junk yard but the problem is GM had these DRACs made with different jumper patterns! Every DRAC i pulled had a different jumper pattern that i assume is specific for the truck itself not the model.Weird. Ive removed the DRAC entire and the truck seems to be running fine. I still want to replace it but not a clue on how. Help please!
