it runs great in forward, but doesnt go in reverse. i was told the selenoids needed to be replaced, but how much would it cost? parts and labor?
how much would it cost to replace the reverse selenoids in a 1998 chevy 1500.? on 1998 Chevrolet 1500 Pickup
First off, there are no reverse solenoids. They were probably referring to the 1-2 and 2-3 shift solenoids. Only the 2-3 shift solenoid is active during reverse operation. If you have a scan tool (not a code scanner) you can check the parameter for that solenoid and see if it is working. If you don't have access to a scan tool, you can just remove the transmission pan and "shotgun" diagnose the problem by replacing the 2-3 shift solenoid (there are 2 solenoids mounted to the valve body and they will be right next to each other and they are identical. In order to not replce both and to tell them apart, it is the one with the RED and YELLOW wires going to it, not the one with the RED and GREEN wires.), but if you can't tell which one it is, you'll have to do both to be sure. If the problem still exists, then you need further diag because you have either an Input Housing Assembly issue, Manual Valve Link disconnected, Reverse Input Clutch Assembly issue or possibly a Lo and Reverse Clutch issue. Most of these will require the transmission be pulled out and dissassembled for repair or complete overhaul. Sorry to not have better news for you.
