1. The notch in the converter drive hub deep enough to clear the pump drive tangs?
2. The converter was not fully seated, and the tangs got "tangled up" with the slots, and when the trans/block bolts were drawn up,,,
3. The converter was not correctly spaced off of the flexplate?

Just the items I've seen cause this.....

I didn't see the installation of the convertors, I just see the damage after. I'll have them double check when installing. One of these was five miles and the other had couple hundred.

Sounds like you built the trans, and the user put it in???
I had the SAME thing happen. [TWICE!]
I gave the user specific instructions, as to how to properly insert the verter, and how to check the plate clearance... One time it lasted a week, the next, upon installation on the engine. :rolleyes:
His bud told me he'd thrown the spacers I gave him, in the trash.....DOH...
Then he got nasty about "warranty"!! Ya, right. :yup: Meet my "little friend".. :gunner:

No, these are two totally different transmissions. Just so happens they both had low miles on them whe this happened. In ten years, I have not had this issue with rotors until now. One of the trannys was built by me and another built by another knowledgable Buick tranny guy.

spacer were used

multiple cars running the same converter & each installation was done & done by buick mechanics. Not some jiffy lube or wack trans shop. First driveshafts, then transmissions, oil leaking exxon valdez with a turbo. I dont know what I see in these damn cars. :rant:

Double checking

Question: If I remember correctly the space between the flexplate and converter should be 1/8" to 3/16"?

:6: Per ATI, Min. 1/16", Max. 3/16" distance between converter and flexplate. Had to check because of the thicker flexplate I just installed. :usa:
