You're taking a very simple example here. Some clutches these days aren't
simple and aren't cheap. The flywheel may also need replacing.

Well it's quite possible to DIY auto box repairs if you take a simple one
as you have with a clutch. Nor are the parts that expensive. I've done
several. Not a modern electronically controlled 5+ speed, though. Yet. ;-)

The bushing/thrust washer that holds the planetary away from

Poor design or materials, then. Most autos go to their grave without
suffering that sort of failure.

Since almost all GM autos from that era die with that failure, your
statement
that "most" live is obviously incorrect. I agree that it's poor design: a
ball
bearing carrier (rather than the cheaper roller bearing and thrust washer)
would last much longer. Doesn't change the facts, however.

But I'm speaking from a UK perspective. The GM autos from that era used
here tended to be the larger ones fitted to Jaguar and Rolls Royce.

Facts depend on where they're gathered from.

When did we start speaking from a UK perspective? (I'm not going
to bother to look, as I no longer care.) This is a global group, not UK
specific, so "facts" should be world-wide, not cherry picked from one
country.

Later.

Indeed. The point I perhaps was trying to make more honestly after you
started talking about 'US GMC autos'. ;-)

No. It's a US-perspective (or even LA-perspective) NG...

Since it *is* a US originated group I try to make it plain where I hail
from.

Wish it were the case with some others writing to car groups with 'uk' in
the title...

What makes it a "US Originated group"?
