I got one 6L90 out of a 2009 CTSV with 10 miles on it and a 6L80 off a 2009 Escalade with 10 miles on it.
Gm says they will all fit each other, I know the one for the Escalade will fit, it's got the same harness but you will have to do your own research on the 6L90. I would assume the 90 just has better parts inside it over the 6L80.
Torque converter should be included but is not guaranteed.
Typically I sell them for 1999$ to 2399$ USD but I never had anything from a H2 with this low mileage so please make offer.
Can ship to Canada or will meet up near Detroit border (windsor) or the U.P of Michigan but only on the 27th of this month. I'm going there for a offroad trip.

Re: H2 Transmission (2) 6L80 And 6L90
The 6L90 is a little longer than the 6L80 and it has a larger output shaft. In other words the 6L90 is more heavy duty than the 6L80!
Other than that they are the basically the same!
So you wouldn't happen to have a kit to install that 6L90 into my 2003 H2 would you???

If there's a kit out there I would guess I could get it.... If the harness plugs in I would think all you need is a PCM flash for it....
