I installed the bearing retainer with no shims like the book said.
When i tightened up the tailshaft housing the input and output shaft jammed up.
I loosened the bearing retainer and it all freed up.
What the hell its already too tight? maybe the bearing cup did seat properly?
When I measure end play do I put the weight of the trans on the tailshaft or just press down on the input shaft with tailshaft free?
YES a clip does go in that groove on the 3/4 slider...so yes it on right.
UPDATE:
1) The bearing cup does seat all the way.
2) The only things that can change the length are the end bearing on the output shaft, the conical bearing between the input and output shaft(hub fits flush with end of shaft), and the bearing on the input shaft..
3) All these bearings are seated and all clips fit.
4) it is about .005.010 too tight. When fully seated there is a noticeable increase in effort to turn the shafts. When loose it takes no effort to turn the input shaft...when tight it takes some effort, can turn with thumb and index finger but not real easy.

I just read your edit and if you can spin it with your thumb and index finger its fine, thats not too tight.
I was thinking it was so tight you couldnt turn it with one hand.
when I built my astro t-5 I had to use 2 hands to turn the input shaft, then again I used automatic transmission assembly lube which is like thick blue vaseline.
to measure the endplay you need a magnetic base dial indicator set up on the end of the input shaft with the bearing retainer installed. push it all the way in and zero the dial, then try to pull it out with your hands, if you see the needle move, thats how thick of a shim you need.

Hey
I got it!
The issue was the bearing between input and output shaft. I pressed it so that it covered the shiny section on the output shaft and fit level with the end of the output shaft. It needed to be pressed on another 1/8th inch or so. I pressed it until it would not move anymore. This is how it was originally I took photos of the old setup before I took it apart....Now it fits great
I did my best to get end play to 0-.003...I know its much less that it was when I took the trans out.
Once everything was bolted down the shafts where still quite easy to turn like before. I shifted the trans through all gears and it was smooth no problems. The shafts spin quiet and smooth in all gears.
One more question. There is a hole in the tail shaft housing near where it meets the case...What goes there...it was empty when i got there. This hole is a vent it goes all the way to the inside...
Oh is Mercon V atf the right stuff to use or should it be dexton 3?
Thanks
