Unhappy Flexplate Upgrade?

2000 Excursion Limited 7.3 (235hp) 4x4 4E0D w/ 203,xxx. Just swaped engine w/ 2001 (275hp) from an F350. Original flexplate was cracked at the bolts so replaced with non OEM flexplate from Autozone (it was Sunday and had no other immediate source) for the original engine 3 weeks ago. It is now making the same rattling noise the original broken plate was. My question - Is the flexplate for the 2001 (275hp) a stronger plate to accomodate the extra hp? I probably should have gone with OEM unless someone has a better recomondation.

Thanks for the reply and if I hadn't already replaced the flex plate I would be interested. Though it's still aftermarket I am crossing my fingers with a plate from a different company.

Sure it's not a balancer issue?

And I'm guessing you torqued the bolts with thread locker?

Are you sure it's not the converter making the rattle noise? There were some issues with those converters.

the flex plates were the same, the 275hp engine wasnt any more powerful.
its just rated higher for a manual.

post a video of the sound, your describing a bad torque converter.

and you dont have a E4OD transmission you have a 4r100.

since your truck is a 2000 you can probably drain the torque converter and see what comes out.
pull the inspection cover off, and turn the flexplate until you see the drain plug for the tq converter
