the 6-speed heavy-duty auto-
matic transmission, standard
on all 5.3l and 6.2l v-8
sierra 1500 series pickups,
has several innovative features
for added control and confi-
dence. Driver shift control
(Dsc) lets you select a range
of gears to suit variable
driving conditions simply
by moving the shift lever to
"m" and using the convenient
tap-up/-down button. tow/Haul
mode raises upshift points to
use more of the engine's power
for acceleration, and raises
downshift points to use engine
braking to slow your sierra for
less noise and harshness.
grade Braking (automatically
activated in tow/Haul mode
but disengaged when Dsc is
activated) senses when you want
to slow your sierra, and if the
appropriate conditions are met,
implements a grade Braking
shift schedule to help you
maintain your desired speed.

all sierra v-8 engines, except
for the 6.0l Hybrid, are
engineered to run on e85 1
ethanol, which is a blend of
15 percent regular gas and
85 percent ethanol.
