Possible misadjusted shift linkage or Park/Neutral Switch on the side of the transmission. I like the adjust shift linkage with the shifter in neutral and the shift lever on the side of the transmission in neutral. Linkage or cable should slip on the transmission lever without pulling on the linkage or lever.

You can hook up a pressure gauge to the trans or unhook a cooler line and start the engine to see if you have fluid flow.
You can remove the pan and check that the manual valve is connected.

When diagnosing I almost always repair the things that I know are wrong 1st and that a lot of times takes care of the problem.

ok thanks a lot for the info I’ve already pulled it back out of the truck again but I’ll open the pan and take a look to make sure everything is still connected properly before I rebuilt it it had shifting issue from 1st to second so I just figured go ahead and replace all the clutches and plates figured that would take care of my problem but it only made it worse off

Don't laugh, these are things professional transmission guy's have done/seen over the years.
No movement at all.
1) extremely low or no fluid. Should be 13qts if cooler was flushed.
2) missing converter or converter bolts
3) broken pump gears
4) broken input drum
pull a cooler line and see if you have some flow. Top line at radiator is return. Rig up a hose to go into a bucket. Have someone start the truck. No flow in 3-5 seconds means it has to come back out.

Issue found When I put the tranny back together I forgot to put the bearing spacer in. Which resulted in the tranny not being able to spin freely. Which in turn shattered the the paddle wheel in the pump. And also the check ball for drive reverse was stuck in the valve body. I’ve replaced the pump and got check ball freed up and tranny worked perfect. But now I have a whole new issue going on. But thankyou everyone for your feed back
