Ken,

Another couple of links -- you may have seen --

Brent Covey's notes on transmission and thrust bearing failure..

http://www.gmcmotorhomeinfo.com/BASICTRAN.html

And an interesting article on cooler restriction and thrust bearing failure. They set up tests on a GM transmission.

http://www.automotix.net/autorepair/audi-v8-engine_repair_guide-720.html

And lastly, a summary on a tuner site -- and one unexpected cause mentioned, poor grounding of the engine, but no real explanation why but a suggested test for poor grounding.

Bob,

The transmission was in the new front clip I installed a few years ago,
behind the 455 I replaced with the 500. It was rebuilt by a reputable shop
in Nashville -- before I put maybe 20,000 miles on it. The removed 455 is
still in my shop on an engine stand, so yesterday I checked end play on its
crank -- imperceptible without putting a gauge on it. So, IF the
transmission has a problem, it's probably arisen during the 11,000 miles
since I installed the 500. Which is not unreasonable, considering what
happened to the thrust bearing this time in <300 miles. If the situation
was as bad when I installed the 500, it certainly wouldn't have lasted as
long as it did before the first failure.

This morning I dug through my stuff and found a couple of 160 psi pressure
gauges. When I decide to get greasy again, I'll connect one of those to
the 425's service port and tee the other into the converter output to the
cooler. It's not going to do much more damage to the engine than is
already done while I check those pressures.

Ken:

You probably already saw this old service bulletin info by "wbryant" on the photo site, but in case you haven't:
