The latter numbers will have to wait until GM thinks it's more timely to release them, but you can figure out which automatic transmissions aren't able to fulfill the opportunities presented by their engines by comparing the power figures for a manual shifter with those of an automatic shifter. If the power numbers are lower with the clutch-less trucks, then you should be wary.
Watching the eyebrows of the GM and Allison engineers, it was also clear to see that they had reason to suspect even the claimed power figures for some automatic powertrains.
On promises of anonymity, GM and Allison engineers suggested that nearly every current diesel attached to an automatic transmission loses 10 per cent of its power in translation, at least.When they promise best-in-class power, performance, torque, durability and quiet operation, however, the people at GM and Allison want to be anything but anonymous.
GM's president, Rick Wagoner, has described the full-size truck platform as ''the economic engine that drives General Motors", and Tom Davis, the GM vice president in charge of the truck group, says ''he wasn't exaggerating a bit. That's why it's so important that every truck we bring out based on this platform be a leader in its segment. The new engine and transmission options will help us put the newest versions of the Silverado and Sierra into exactly that position."
