ok fella'*. I got the transmission assembeled and installed.

The thing shifts perfectly and no excessive RPM'*. But I've only driven it around and had it running for about 4 hours total.

Only tiime will tell.

​​​​Yes. The whine is completely gone.

Now I just have to deal with a bent control arm on the back right, a bent tie rod end on the front right. Leak in the power steering system, leak from valve cover intake manifold area, a leak from the oil filter housing on the front of the motor, and a leak from what appears to be coming from the front main seal on the engine.

I also forgot to mention that in the technical service bulletin it did suggest that part of the diagnosis and troubleshooting process you were supposed to put the vehicle in neutral hold the break and read the engine and hold it at certain RPM range maybe 2500. Is that may fix the issue, I could see that fixing the issue because when I had the bearing out before I uninstalled it I took a piece of 2500 grit sandpaper and I sanded the needle bearings with the sandpaper for quite a while and it actually worked the bearings down to a point that they were I think smooth enough that I could have reinstalled them and it would have been quiet. But I opted to put in the new part that I'd already ordered.

I hope this info helps out somebody in the future.
