Transgo Shift Kit or Transgo Reprogramming Kit???

[Tantrik77]

I have the 4L80E transmission in my 2002 1500hd and am looking to upgrade, so I was wondering what the differences were between the trango shift kit and the transgo reprogramming kit. Can I install both and have them work in conjunction? Or is one way better than the other? What upgrades do yall recommend so it will hold up with a supercharger?

I would get the HD2 kit for the 4L80E. most bang for the buck.

These can be installed without tranny removal, correct?

Who has best prices?

check their ebay store, usually cheaper.

OK; got the kit.

The instructions are bit confusing, at best.

I was just glancing of the instructions before I took anything apart so I'd have an idea of what to expect.

Anyway, the drilling of holes that are mentioned; are they all done to the valvebody or some to the tranny itself also?
