So I know there's a lot of talk about Tq management on these forums. For those who aren't familiar with the term, "torque management" is a term used to describe the situation when a manufacturer purposefully reduces engine output/power by computer in certain situations to protect various parts of the driveline such as transmission and axles. In this video, the Chief Engineer for the Duramax HD trucks says they limit power in 1st gear, and full power is available in 2-6th gears. It would be nice to know (from a reliable source like in this case) in which gears Ram and Ford limit output. I'm confident they both have the same feature.Here's the video interview:VIDEONote that I modified the link so the video starts at the point where tq management is discussed (12:48).

Not much can be done with it, but still good to know from a consumer stand point. I see TM as a good thing to limit driveline wear. Of course there are cases when someone may want a modified tune to have that removed.

Because we like to know stuff. simple answer. thanks ib516chevman

"Rainbow Stew"????

I always thought Cummins12V chased rainbows! :B

Yep! Tomorrow morning I will be hooking my little 23K Mobile Suites to my little Cummins powered pickemup truk and have my little Motorcycle trailer hooked to my little RV with two Cruiser bikes heading North to the land of Rainbows! All at a measly 35K combined. Hope I can make it up and over the Siskiyou's in Northern CA. All that with Torque Management.

So how does a 6 speed Mercedes-Benz manual trans signal to the little Cummings to manage the torques?

In what application is a MB manual transmission mated to a Cummins? It has never been in a Dodge/RAM truck.

It has been in a Dodge/Ram since 2005.5....

The G56 is a MB transmission.

LMFAO... This BM guy really didn't know!

Torque management is a good thing. We don't need full torque in the lower gears where we get great torque multiplication, but we do need it in the higher gears where we lose torque multiplication. A transmission, transfercase, driveshaft, and rear end that could handle 900 lb/ft in 1st gear would be size and cost prohibitive for nearly everyone.

The ECM has the ability to calculate the gear in manual trans trucks.

On my 2005 I have lowered the minimum speed for cruise control to 20 mph. If I am in 3rd gear at 25 mph it will not engage cruise control, but as soon as I up-shift to 4th I can engage cruise control. I am still working with MADS on how to change it. This will be the same calculation used to use torque management on the manuals (MB trans or NV trans).

Also, is Cummins... no G.

^^^^^ Seems you are having an argument with me, I am not having one with you.

"When a truck gets down to 11-1200 rpm with your foot on the floor it does NOT know what gear to be in"

Mine does not get down that low when pulling a grade, not even close.

Not sure why you are "Sorry"

I am only commenting on what my truck does and does not do.

I'm sorry because I know the Aisin to you is the greatest thing since sliced bread but the two that I have owned have not been.
