Hummer H2 Manual Transmission Swap - Pemliminary Questions I am helping a friend (who is helping me with some fabrication chores on my car) with his truck.
2003 Hummer H2, 408 iron block with a Magnuson blower. Figure around 700 hp, give or take. Stock 4l65-E's seem to last for several months
then the output shafts snap. He wants to convert the truck to a manual transmission.
I think I have the research done to be able to do the physical installation to get the NV4500 and transfer case (either whatever is native behind a NV4500, the electronic version of the same or an Atlas Case) installed in the truck.
I have some questions about the electronics.
I apologize if these questions are basic, but I want to make sure that I know what needs to be done.
The plan will be to use HP Tuners (which I should have by that time). I have done tuning using other programs on non-GM applications, so I am familiar with it, but have never done anything like this.
1. Does HP Tuners have the capability to change everything necessary to have the truck run with a manual (assume that stuff like the clutch interlock is taken care of and that the base tune is not going to be altered)?
2. What, if anything, needs to be done to the traction control system and can HP tuners do it?
Thanks in advance for any advice or a point in the right direction.

Not a lot of guys around here who have installed NV4500s behind their engines... I'm in the process of figuring out my 6.0L / NV4500 swap into my 1980 GMC 3/4 ton 4x4, once I've figured it out, I'll be posting exactly how I did it, as it should work for any 4.8L, 5.3L, or 6.0L with a recessed crank...

I am not sure if hp does or not. But, In efilive you can do what is called a segment transfer. That means that you can make any combo you want using factory files.. If you want say a manual on your truck and you are using a certian operating system, you just find another file with that same operating system that has the trans you want, Then you just copy the segments over in one click you are done. It changes all the things in the back ground that you would never have access to.

I might have to look into efilive more carefully.

If you go to www.efilive.com and then to downloads, download the latest version, then open up a bin file and go to Edit button at the top, there you will see the segment transfer stuff.

Thanks! I might take you up on that. I am guessing you could knock of a tune for this one from scratch in your sleep. You did a tune for one of my RX-7s and it was excellent.
I might also contact you for my BMW swap if I chicken out
