Re: 4L80e Tranny swap in an 03 H2
you are correct...
for some reason i was thinking that the 2008+ H2's ahd the 4L80 in them, but actually they have the 6L80.
that is what i was essentially thinking. getting a tranny from a newer H2 and throwing it in my 03.
i just want the 6sp for the extra MPG and ability to take more HP. i dont plan on doing a SC/TC or anything like that. mostly bolt on stuff.. but when this engine finally goes, would like to throw a big block in there and have it connect to the drivetrain without any serious issues. big block as in a 427 or a 454... atleast i will have an excuse for ****ty MPG after that
