So my uncle has a 05' 2500. Things happening: truck won't shift into 4th/OD, MPH needle moves in 3-5mph increments. Ok, things that have been replaced: rebuild trans, new PNRDL switch replaced with at transmission shop. So here is what we found: no codes active, no check engine light, truck will drive fine if unplug the instrument clust. Had the cluster sent to a guy who said he fixed/soldered some components. My uncle said he had this done a year ago and hadn't had a issue since. All the sudden this issue is back. We did open the cluster and tried soldering the same components that looked like the guy had done. It worked for about day. Could buy a new/used cluster, but afraid it will have the same issue in the future. Any help?
