Keith, this is closer to home than you might think. The 4-speed transaxles
were developed by Jay Eitel, a CORSA member, as a part of the super-duty
program in the early 60's. Jay has one in a '69, driven by a Jag V12. Read all
about it at the CORSA web area under "Gary Aube". For that transaxle, two
powerglides were mated in series. Naturally all the ratios were changed, but
essentially you have a dual-range powerglide. Two powerglide shifts, then
change the range, followed by two more powerglide shifts. This is analogous to the
4-speed hydromatics of the 50s. The Pontiac racing 4-speed transaxles were
manually controlled. Jay developed and built an automatic control for his,
so he has the only "automatic" one. Jay's boss was Bill Collins (assistant
chief engineer under DeLorean). Bill's later claim to fame was as engineer for
the DeLorean and after that the Vixen motorhome, both of which used
transaxles. There are Vixen owners among us (I was). Tom Zimmerman (on this list) is
noodling on how to combine powerglides (I think) and how to maybe use the
Delorean/Vixen/Renault UN-15-speed transaxle in a Corvair.

Alright, I waited to see if anyone else would mention this and as no one has
here goes. A couple weeks a go I was watching "Muscle Cars" on "Spike" and
in between welding and grinding on various things they followed a group of 4
or 5 Pontiacs built and raced by a now deceased famous Pontiac guy. The name
was known to me (but now forgotten). Arnie (The Farmer) Beswick maybe? His
family was selling his collection. His cars were quite dominant in the early
and mid '60s. At the auction block they showed the cars and my attention was
drawn to an early Tempest wagon (transaxle equipped of course). Yes the bastard
cousin to the Vair as my Uncle referred to his. As they moved the camera
around and looked into the back, the narrator mentioned the PG had been
engineered with a second planetary gear set making for 4 forward speeds! Well that
caught my ear. Now I have no idea how this works. Maybe someone out there knows
this set up?
BTW this "guy " was know for his hot 421 Super Duty Pontiacs. That is what
was in the Tempest so this was one stout transaxle.
Alright figure out how this works and report back I can't wait to have a 4
speed auto Vair.
P.S. I tracked down some more info. Actually the same car being sold again.
The link should take you to Mecum Auctions. It mentions parts of two PGs
being used.
