I'm new here but judging by the post dates it seem to be very dead here.

I had the same problem with my T-Bird. It wound up getting worse and worse. I found it did it more under a load pulling a hill . I was the transmission I rebuilt it and all fine now. 160k miles. Good Luck.

er2cc is probably right. Our trannys are CRAP straight from the factory. Try checking www.tccoa.com. Look for the link called technical articles. In it there is a link that talks about good shift kits that eliminate the 1-2 shift clutch-pack-overlap. This would be a god start but, it sounds like you might want to rebuild it first anyway. sounds pretty boned to me.
