Two possible problems and my lack of understanding here.
If you put in a high performance torque converter(don't know if you did) it might require a slightly smaller flex plate. I had this happen once long ago and the performance TC required a plate where the holes were about 1/4 inch different. Took me all day to figure that one out. Doh.
I am not sure I understand your comment that the TC turns when you turn the flywheel. If the flywheel is connected to the TC it should turn. The tranny usually does not prevent the TC from turning since it is a fluid coupling at least before they came out with locking TCs.
Last TC I played with was the old fashioned kind. The only thing that the TC shell is connected to is the pump drive and that should turn freely, at least in my limited experience. All the stuff connecting the TC to the input shaft of the tranny is inside the TC shell and does freewheel.
Back to the pump drive... I once spent a day trying to install a TC before I realized the TC shaft has usually two swuare notches in it. Those notches mate with two square pegs on the drive ring for the pump. Sometimes the ring will slip off center and make it very hard to insert the "snout" of the TC into the tranny. Check that the rign is centered and then gently line the tc notches up, should slide right into place.
Good Luck,

That is weird. So you are saying the flywheel turns while you are turning the TC to get the holes lined up?
I don't have a lot of experience with your model but most flywheels or flex plates are bolted to the engine crank shaft. If the flywheel turns the engine should turn. But normally the engine should be tight enough that the flywheel won't turn unless you are putting a lot of pressure on it.
So... 1) Is the flywheel bolted to the crank? I think almost all models are bolted to the crank. If not, then bolt it up before bolting the TC to the flywheel.
2) When the flywheel turns, is the engine also turning? Have a buddy watch the front pulley to check. If it does, then there may be an interference problem which is putting enough pressure on the TC and Flywheel that they cannot turn independent of each other. This might be a problem with the seating depth of the TC into the pump housing on the tranny as mentioned previously. Or maybe you just need to weasle the tranny back just a skosh to get some clearance so you can line the TC and Flywheel up. Then tighten the tranny back up to the engine.
My guess is #2, the TC is pressing too hard against the flywheel for some reason. Make sure the TC is seated and maybe loosen the bell housing to engine bolts a bit to get some clearance. The few times I have done this job, it was not hard to do at all, as long as the TC was fully seated.
Just some ideas.
