Re: How is the new six speed transmission for Wrangler?
To quote an article in the November issue of HOTROD magazine, about the new
modular GM six-speed auto that is coming out this fall,
"The more gears in the transmission, the wider the potential ratio range
from First to the top gear can be without causing the engine rpm to drop too
low between shifts. The wider the transmission's ratio range, the easier it
is to combine a low First gear to launch the car with a steep top gear for
overdrive cruising. GM engineers estimates that the wide ratio will help to
reduce the 0-60 times by as much as 7%.
BMW and Mercedes already offer a seven speed auto (and soon an eight) to
keep the relatively low torque, overhead cammed engines in the fat part of
their powerbands."
It is an interesting read.

Re: How is the new six speed transmission for Wrangler?
I think the 7 speed is only available in the BMW M5 and M6, which have 500hp
@ 7750rpm
and 383lb ft at 6100 ; I bet that engine gives a reasonable torque figure
even at lower revs.

Actually Ludwigsburg was founded in the early 1700's not 1935...
