    alright, i've heard mixed responses from people on this. I appreciate any input

    will a 4L80e that came from a 2000 2500hd OBS (with 350) bolt up to my 04' 5.3?

    I've heard that everything fits but one bolt, and that it should be fine. is this true? thanks for the help, i really have to find out by tomorrow.

    if you pull the 80e out it will bolt up just fine to your 4.8L. they have the same bolt pattern. someone correct if i'm wrong, but i'm positive you don't have change anything in order for the trans to fit. except the crossmember and wiring harness.

    good luck,

    allen

    Guess I was wrong
    2005 RCSB 4.8L TVS1900 9 psi
    2005 ECSB 4.8L TVS1900 5 psi

    That makes 9.6L @ 14psi
