The shift kit dose not control torque management. It dose come with some resisters and some other different parts to make your trans shift better and without the loss of power. I think it makes your PMC work allot better with it. I love the new feel of my trany. My truck takes off like a rocket ship and chirps the tires when shifting into 2nd gear. I can get it to break the tires lose from a stand still just by hitting about half throdle. If I power brake I can just sit in one spot and roast my tires intell they burn off.

 

Problem is that us Durango R/T owners have that crappy Full Time AWD system! Wished I just had a plain ole part timer so I can stay in 2WD most of the time. Problaby save some gas too! Then I can chirp or smoke some rubber too!
