Yes, with derated HP and torque, I think the same as the CC.

Yes it is the same G56 transmission as 06 with a few upgradeds and new ratios. Like jibber said they are derated in HP. My dad has 1 stick and 1 automatic orderd and both should be here the second week of March.

Depends on if he's talking about the cab/chassis or the full body pick up, I don't think there's any derating in the pick up regardless of tranny option. what truck are you referring to Cumminspower5.9?

The 2500/3500 pickup has derated HP and torque. There is a constant offset in the HP curve at any given RPM, but the list the same 350 HP at 2 different RPMs. [email protected],000 for the auto and [email protected] for the manual. There is some rounding in there, because I am looking at the HP & torque curve and it clearly showes the auto higher.

The torque derating is more significant with what looks like a constant 35-40 foot-# offset. Peak torque is [email protected] in the auto and [email protected] in the maual.

That's weird, don't you usually lose HP and torque with an automatic.
