Premature Transmission Failure

I gotta ask why the overkill on the clutch?
You have other plans later down the line that will significantly raise power levels?

I would try and stick with an organic face clutch disc is possible.
This will soften the drivetrain shock.
No need to go metallic puck clutch disc unless you're making over 300 lb-ft.

Would it be possible to go thicker on the trans oil?


I think what's killing your transmissions is the brief episodes of 10k RPM's.
No OEM trans is rated to handle revs that high...
This explains all the bad bearings.
