I have a 92 d250 auto w/overdrive.My speedometer doesn't work and my trans will not go into overdrive.I took the speedo gear out of the tail end of the trans and it was worn down.The one I took out was yellow.I replaced it with a green one and it worked a couple miles and the teeth got eaten off and speedo quit again,The dodge dealer(parts) informed me the yellow 30 tooth gear has been discontinued.He also informed me that all the gears are the same diameter just different number gears depending on gear ratio and tire size.My question is do I have an internal trans problem that's going to keep eating up gears?If so is this a hard fix?I would hate to have to take the trans out and a apart just for speedo.But I want to have overdrive and I have been told if the speedo doesn't work this could be the reason I have no overdrive.Any help would be appreciated.By the way I just bought the truck with this problem.Thanks
new pcm solved everything but my overdrive and cruise control,I can live without cruise.Now I have a code 24 from the pcm,which is TPS shorted or open.I put a pot on and still no overdrive.Does anyone have a pic where the wires go in the trans. for the OD solenoid?I thought I found it but I was toldl it was the neutral safety switch.
