trans problem

[John Lagnese]

Hi,
Has anyone run into the flanges on the trans getting loose? I have an 83
4000. The tranny had a leak from the flanges. I changed the seals and
found the driveshaft flanges were wobbling around noticeably. I changed
the tran. Its now happening again. Could my inner cv joints be gone? How
can you tell? Could the engine/tranny not be aligned? ( I put in a Fox
1.8l) I want to resolve this before changing the tranny again.
Thanks, John
