93 k1500 350TBI codes and hesitation help?
My 93 extended cab k1500 has a bad hesitation when first pulling out from a stop and if I step on it. Here what I did. Changed fuel filter, did oil change & filter, plugs wires , cap & rotor. I pulled the codes and was getting 6 of them. 1 was the throttle voltage was low so I replaced it. 2. Was fuel relay. So I replaced that. Getting code 72 saying output speed sensor, another code saying transmission temperature is high, trans temp hot. And something saying that something about A &B shift module. So after replacing the fuel relay and tps my service engine light went off and those codes are now gone. But I'm puzzled by the 4 tranny codes that I am getting . The little info I found about them says it could just be a broken wire. But I don't know where to start.. Any help,would be. Appreciated
