I have a 2005 2500 quad cab diesel 4x4 with just over 242,000 miles on it and have been having an issue with the shifter "sticking" when shifting out of park. I have to pull a little harder to get it into gear. Then there is no problem. I took it to my dealer and they said that the valve body needs to be replaced. Does this sound right? I was going to do this but now am told that the part is on back order, there are 80 orders before me nationwide and that FCA may not be making the part anymore. The only other option is a reman and that is about $6000. If FCA is making re-manufactured ones, where are they getting the part? No one knows. I would appreciate any ideas on how I can get this shifting issue resolved and any info on how dangerous it may be. I bought the truck new in October of 2014, so all the miles are ones that I put on it. I love it and want to keep it running smooth. Thanks in advance!
