HELP Trans R&R
Ok so we removed a trans for a friends 99 ecsb 4.8 4l60e
heres the deal we swapped the converter bellhousing and inputshaft into the new trans. Now the converter anbd flexplate are touching with it bolted back up.. I have double checked the converter the thing is snug.. but its still so tight i cant turn it... No idea guys... What should i check?

Now the bad news, there is a good possibility that if you have tightened the bell housing bolts, you have cracked the pumped..

Do you mean you can't turn the converter? Did you bolt it up? If you did, you can't turn it because the converter hub is pressing against the pump rotor (which is probably broken now). I know this because I just did it like two months ago.
On a 4l60e, you should have about 1.125" (1 1/8) from the bellhousing to the pads where the mounting screws are. Meaning take a straight edge across the bellhousing and measure to the pads. If it's anything more than that (it would probably be significant, like only 5/8" instead of 1 1/8") then you didn't have it seated fully.
If you broke the pump rotor it's not expensive, but it is time consuming and a pain, and I would recommend you let a shop do it (they'll charge $100-200) if it's already out of the car.
I replaced my pump rotor and the misc parts and it was like $60 in parts, but I did a bad job installing it and ended up messing up one of the pump bolt threads and long story short it was bad.
But maybe you're a better mechanic than me (doesn't take much, heh).

You have three engagement points, the first two are easy the last is more difficult.
1= stator splines
2= input shaft splines
3= pump lugs (what most miss)
If you have no converter clearance = converter not fully seated
I know you said you triple checked, but that is the only variable.

BTW, after re-reading your first post, you mentioned you changed the "input shaft"
Are you saying that you actually removed the pump and pulled the entire input drum from one transmission and installed in another?

If the input drum and reverse input drum is is not fully indexed and bottomed out, the pump will not fully seat and could cause your symptom as well.
Can you/did you turn the input shaft?
(not the converter, but the actual input shaft)
Out of curiosity, why was the pumps swapped?
