Alright folks, got in to town today to see my transmission guy, and he ran the scanner on the truck. Pulled a 503 (Intermittent Speedometer issue) is what it said. He pulled the plug, cleaned it, replugged it, and cleared the computer of any logged errors for me. He told me to trace the wiring and see if there was a bare wire anywhere as well. Other than that he found no issues. Thank God!
