<P class=prHeadline>New Allison 1000 Transmission Offers Six-Speed Performance

PONTIAC , MICH.
The Allison 1000 transmission grows from a five-speed automatic to a
first-in-class six-speed automatic for the 2006 Chevrolet Silverado HD and GMC
Sierra HD trucks equipped with the Duramax 6600 6.6L V-8 diesel or Vortec 8100
8.1L V-8. Also new for 2006, the Allison 1000 six-speed features a class-first
tap-shift range selection function, as well as offering enhanced fuel mileage,
quietness and control. The range selection function allows the driver to easily
select the desired gears to match driving conditions, such as towing a trailer
on a steep grade.</P>


“Changes to the Allison 1000 represent a ‘best of all worlds’ scenario,” said
Kevin Wayman, Allison 1000 chief engineer. “Performance, quietness and fuel
mileage are all enhanced without degradation to product durability.”</P>


The sixth gear – essentially a second overdrive gear – enables a wide, 5.08:1
overall forward gear ratio coverage and allows the vehicle’s engine to operate
at lower rpm, particularly during higher-speed driving on highways and freeways.
Its 0.61 ratio sixth gear provides a 1550-rpm engine speed at 60 mph, compared
with the five-speed transmission’s 1800-rpm engine speed at 60 mph. The engine
uses less fuel at lower rpm, enabling increased fuel mileage and range. The
ratios of gears 1 through 5 remain the same as the Allison 1000 five-speed,
including the 0.71:1 fifth gear.</P>


A tow/haul mode is retained on the Allison 1000 six-speed, but it is
complemented by a new range selection feature. It allows the driver to select
the desired gears, via a thumb-activated switch on the shifter, providing a
feeling of enhanced control in unique driving situations, such as towing on a
steep grade. The range selection feature holds the gear pre-selected by the
driver and electronic safeguards prevent the transmission from being shifted in
a manner that could cause engine damage or loss of vehicle control. Grade
braking and cruise grade braking are only available when the tow/haul mode is
selected and the transmission is not in the range selection mode.</P>


Diesel-engine vehicles equipped with the Allison 1000 six-speed feature
cruise control grade braking. Working in harmony with the tow/haul mode, the
cruise grade braking system will automatically downshift to help maintain the
pre-selected cruise speed when driving on downhill grades.</P>


A new low-traction mode also is standard on vehicles equipped with the diesel
engine. When the driver selects second gear while stopped and wheel slip occurs,
the transmission torque-manages the engine to limit tire slip on slippery road
surfaces.</P>


In addition to the sixth gear and range selection feature, the Allison 1000
also benefits from complementary upgrades that include:</P>
<UL>
<LI>Upgraded 310-mm torque converter that improves torque capacity
<LI>New 22-tooth pump that improves NVH
<LI>New solenoids provide better converter lock-up control and shift feel
<LI>Upgraded rotating clutch that improves torque capacity
<LI>New A40, 32-bit transmission control module </LI>[/list]

The Allison 1000 also has a unique, GM-patented elevated idle mode, which
allows for faster interior warm-up of diesel-equipped vehicles. The system,
which is activated through the vehicle’s driver information center, is
synchronized with the engine. When elevated idle is active, the transmission
increases the load on the engine so that it will generate heat more quickly and
warm the interior in less time.</P>


In 2004, GM Powertrain announced plans to introduce 10 six-speed automatic
transmissions globally by the end of the decade. The introduction of the new
Allison 1000 six-speed automatic is another step towards realizing that
goal.</P>
