Lexus and Hyundai currently have 8. Dodge will soon have 9. Now
seems Hyundai is upping the ante and developing a 10-speed automatic
transmission. Good god, where does this end? Soon cars will be
sporting enough gears to make a trucker blush.

Turboglide
transmission. Very different steady tune from the exhaust while the car
increased
in speed but the engine RPM didn't change that much.
Because of its unique operating characteristics, Turboglide did not
require large changes
in engine RPM even with very large differences in car speed or desired
engine output. In fact,
accelerating from rest, the engine speed would remain nearly
constant(with no movement of
the accelerator), even as the vehicle accelerated.

Dick,
Are you speaking of GM's old 2-speed Powerglide?
I had one of those 2-speeds in a 60's Impala I used to own.

Thus spake Dickr <dic...@frontier.com> :
By most counts, the Poweglide is the most used transmission in racing.
Primarily because of the monsterous number of cars running one in drag
racing. I've even seen 2002 F-Birds running one, since by the time
you can manage to get to third you're shutting down.
I'll have one in my 351W (408) car. But not a GM product per se'

So Kim Jung Ill shows up at the barbecue. "Wait,"
says Qadaffi, "you don't have any peircings." "If you
starve your people enough they'll be too weak to rebbel."
"You have the same number of holes in your head as when
you were born," says bin Laden. "My compound had radar
and antiacraft misslles." "Your neck," shouted Hussein,
"it's the same length." "I didn't piss on W's father."
"Then what happened?" the three asked. "Damned counterfiet
Lipitor and insulin!"

to
gear set you have all sorts of possible ratios. Now that most
transmissions are controlled electronically rather then by simple
hydraulic valves, it's almost trivial to add another "gear". I read
some years back that in many of these transmissions they often
"skipped" one or more of the possible ratios depending on how hard you
were accelerating since most of the time you don't need all of them to
move things along. It would be interesting to talk to a car makers
autobox engineer about this.

your foot in it, you're not concerned about economy, you want
acceleration, so it would make little sense to hit all the gears. But
if you're cruising, the trans should then act to keep the engine in
it's sweet spot for best MPG. Or so it seems.

I'm sure skipping would have to happen quite often. If you're putting
