Thanks for the video. Yep, it is not shifting. Can I ask did it do this before you did the repair? If so I would try a replacement PCM because if it were a connection problem you would would have a code that pertained to it. Here are the instructions. Check out the diagrams (below). Please let us know what happens.

It was kind of but when I rebuilt the transmission the third and fourth clutches were toast and the seals were bad. I will check into the PCM. Though is there a way to just reset it and see if that works? I don't have a ton of money to just throw at this truck and see what happens, lol.

Also, when I changed my distributor it did throw out a p034 trouble code and p300. But when I adjusted the distributor it fixed that issue and the code went away. So if it is still able to put codes out does that mean its still working? I don't know. I dislike electronic issues.

I would go back through the transmission then it sounds like you might have folded a lip seal or forgot an o ring. Let us know what happens and please upload pictures or videos of the problem.
