my 2003 ram 3500 has a shuttle shift problem I know change the Governor pressure sol. and the Governor transducer i had them changed and that didnt fix the problem took truck back to place that replaced them and had them checked for defective part and there isn't anything wrong with them. the shop had to jack up the truck and start and put into gear to get it to start doing it after 60 miles the truck started shuttle shifting again. what was found to cause it was the truck temp at 181 deg or higher the higher the temp over 181 the worse the problem. when the temp gets below 181 the problem stops then when you let the temp get over 181 it starts again and that it appears the computer is telling it to do that. also with the temp over 181 when it starts the shift problem you can put truck in park and then back to drive and it will stop for that seres then it will start all over again. does anyone know what the problem is or has anyone had the same problem?

 

INTERESTING. mine does the same thing, but if i give it a little more throttle on acceleration, it doesnt do it. I wondered about the gov pres sol too but never changed it, I also notice that if the temps are cooler (like you said) it don't shuttleshift around. I also noticed if I'm hooked up to the car trailer (even empty) it doesnt do it either. I suppose it's a load based thing. I put a shift kit in mine and it didnt change a thing. Any help?

 

don't know mine is in the dodge shop today and there looking for the cause i will post the results on here. I was just wondering if anyone else had the same problem and if anyone had found a fix.

 

well the dodge shop has hopefully found the problem it seams the valve body is bypassing at temps over 181 deg and the governor pressure solenoid is trying to compensate for the pressure loss. The new valve body will be here tomorrow then we will know for sure.Keep your fingers crossed
