HELP New clutch now NO 2nd or 4th

[nikstang]

I have new clutch, flywheel, t/o retainer and all. Seems fine shifting and taking off in 1st is good and 3rd, 5th, and reverse engage, but 2nd and 4th are now grinding and not engaging at all. The other gears are making a rumble sound as well. I torqued everything to spec and double checked them. I \am thinking but don't know if something may have fallen out of place when R/R the retainer.

That is the only thing that I can think of. Any thoughts or experience in this area?
I figure I will have to pull the tranny again, but want a clue as to what to look for before i go to the trouble again.

First place Id look is that the throwout bearing was installed right on the clutch fork, and the clutch fork is attached properly to the pivot ball on the bellhousing.
