Anthony, I'm sure you got it figured out by now. Anyways here's some pics from cobalt ss. You may have to register on their site to view. But well worth it for anyone doing this mod. BTW I have had the shift plus for probably a year or better and run it on the firmest it will go. No issues at all.

I installed one in my son's cobalt, he has had in for close to a year now and so far no problems with the trans, the shifts are nice quick/firm. The only down side is that the car lurches/jumps when you put in gear.
