Hello and thank you for using Just Answer. My name is ***** ***** I'd like to try and help. I am sorry that you are having issues with your truck. I know this can be frustrating. There are 2 different things which are common on these that I would check. The first is to remove the PTO cover on the rear of the trans. This has the range cone on it. Check to see if this feels loose. If it does then the rear of the trans will need to come off to have that range cone and material replaced on it. If that is found to be fine then you will need to run the clutch drag test and gear test. If those test come out fine then I would replace the ribbon harness in the trans. This is the harness that goes from the TCM to the gear housing. We have had a lot of issues with them. I would also verify that when the trans was out there was zero play in the input shaft. I hope this helps you on the right path. Thank you.
