I've noticed some trucks have a +/- for choosing your gear on the column shifter. Can that be added to any truck? I've got the 4 speed transmission, the only trucks I've seen it in have been HD's and 1500 crew cabs with the 6 speed transmission. Just wondering if its as simple as adding in the DIC controls or if its not worth the effort..

No, this is a 6 speed tranny feature only(6l80E or Allison). The 4 speed tranny's computer won't know what to do with it.

I got it on mine & its pretty cool. Will come standard with any truck with a 6 speed.
