That yoke may have bottomed out and damaged the seal inside the yoke.

Also the out side of the seal surface doesn't look smooth in the 1 image where the shaft is pulled back. If its not smooth, It will wear the output shaft seal and leak.

I can't tell from the video if its leaking from the inside of the yoke or if its leaking at the outer seal.

 

The yellow arrow is what I am referring to about the yoke and the output seal.

 

From the Video, It appears it is leaking from the center of the Yoke.

 

I believe there is a seal in there that can go bad.

 

the last two pictures is how the old transmission was leaking and after went out
the first picture is of how the new transmission is sitting right now and only leaks on uphill
replacing it will fix it from leaking and the angles?

 

The Angles is something you have to measure and tell us. That's not causing it to leak though.
