I am trying to troubleshoot an issue I have recently discovered with a 1996 F250 7.3L SRW. The vehicle had been sitting for a couple months without being ran, and last week in preparation for me to come and pick it up ( I am Active Duty Army stationed in TX and truck is located in Oregon ) my father got the truck running and took it for a quick ride just to check everything out. He noticed that cruise control no longer works as it did previously as well as not wanting to shift into 4th / OD unless under heavy acceleration but will then come back out into 3rd with TC Lock up, so at 65 Mph its running about 2500 Rpm's. there is no CEL and the OD Light does not flash, he also stated that all brake lights work correctly and the fuses all looked good. I am headed out there this weekend to get the truck and drive back to Texas with it but want to rectify this issue(s) as I'm not sure where to look at this point and don't want to encounter issues during the trip. The Truck has 181k on the ODO and had a transmission rebuild roughly 3 years / 70k miles ago which it has had 0 issues since the rebuild until recently when it had sat and not ran for a couple months.
