help from a transmission god!!

I have a 97 gmc z71 4l60e 4x4 5.7-- The sun shell gear went out on me -- I took out the tranny and replaced it myself, and had it rebuilt-- Everything has been fine for the past 6000 miles-- now I have a rattling noise coming from the bell housing-- Come to find out 1 of the 3 torque convertor bolts were like a 1/4 turn loose (obviously forgot the loctite) So I tightened that 1 up and the other 2 were fine-- started the truck and did not have the sound and the torque convertor and flywheel spun fine in a strait line and not wobbling.
Put the truck back together and test drove it, and the rattling is there still-- I believe that the t.c. bolts are rubbing against the heat shield-- WHY??? Everything is a pretty tight fit and it seems like if anything is out of line you wont get it back together--
And also there is some excessive vibration in the truck while in park and in drive-- hit the gas in park and there is some vibration along w/ going down the road -- all tranny mounts are tight-- This is my only vehicle back and forth to work, and I just got back to work after being off for
6 mths. Just put a new exhaust on it from manifolds to convertors--
Please help with this, have no idea where to go next!! Thank you

ANYBODY-- have and idea??

Although I can't help you, I really don't know much about trannys, but seeing as you're getting no hits here, go post in the chevy C/K forum, it other than the grill and name it's the same truck as the chevy, and there's usualy more people posting and visiting over there. Good luck.
