repeated flexplate failure after factory engine installation

[autoquest]

What causes repeated flexplate failure? A 1995 for windstar had a factory rebuild engine installed under warranty and now has had 2 flexplates in 30000 miles and now needs a 3rd. Torque converter and crankshaft where replaced after 2nd failure. Lasted 15000 more miles and cracked again. Any ideas?

the first thing that comes to my mind is misalignment of the transmission relative to the engine (or vice-versa).

I agree chek your mounts and possibily get a body manual so you can make some measurments and find out what bent, twisted, or mis-aligned.
