    Hummer H2 t-case

    I've been having lots of problems with my 4wd due to some problems in my tranfer case and I want to know if a transfer case from a H2 will bolt on my truck, and if it is going to work right? that's because a buddy of mine is selling a t-case from an H2 that he is parting out.. (engine is gone )
    thanks in advance

    i think the tranny is still there, but I'm not sure about swaping my 60 for a 80 cause I've heard there is a lose of performance in the swap.. but I might be wrong..

    I'm not sure they ever put an 80e in a Hummer. TRTTurbo retrofit one into a built H2 and it took a ton of work and hours to work all the bugs out of it, the owner would not accept a full manual valvebody.

    That's more than someone that bought one. A 2500 Suburban has either an LQ4 or an 8100 with a 4L80 trans and a big rear. An H2 is based on the 2500 Suburban and has a 65? Dumb. I would still say get a Chevy T/C. Hummers have weirdo parts.
