    The above is where my question lies.. Unless I'm not understanding correctly this is a brand new, never used converter b/c it was rebuilt. If so, then it's reasonable that something was not made/assembled properly based on the trans it's going in.

    Before blaming the converter tho, I would definitely make sure the thrust clearance and converter clearances are spot on or a tad loose first but keep the above in the back of my mind.. I have a feeling that a stock flex plate and known good bearing clearance will fix the ordeal..

    I get what your saying with the TC. But it had 100k miles on it in this same transmission. Same TC builder that made it 100k miles ago. He knew what trans it's going in, and it was reliable for years.

    Plenty of people run this flexplate without issue.. and I only bought it because the engine builders recommended it. It was not purchased and part of the plan until they told me the stock ones are know to "grenade".

    This same TC builder opened and inspected it after the failure. Said nothing was broken, or off measurement.

    He could be lieing. But I don't think so. Plus I know his first build worked perfect for me. I trust him from my year's of experience using his product.

    And thank you man. I can't say it enough. Every reply someone does really helps the mental depression about the situation ha.

    Transmission was Dyno'd at ArtCarr transmissions/California performance transmissions.

    It had no issues. Good pressure, Good shifting, Good tcc lock up, worked perfect. It didnt kill their trans dyno motor.

    Some people that have reviewed the build sheet says from the engine the engine looks great on paper.

    Build Sheet: https://prnt.sc/qusbl2

    How would the engine fail in a way that would only wear the transmission side of the thrust bearing and not the other side? or what would cause that symptom?

    Im looking at picking up the engine parts from MMR this week. Without an exact cause, I will not let myself rebuild and try again with another built motor (and I cant afford it).

    I can then take some pictures from the tear down.

    Foreign particulate matter finding its way between the crank thrust face and the thrust bearing insert material.
