Greetings, all

Are all 4L80s the same, outside of the bell housing? Will a trans from an '03 2500 4wd 6.0 work in a '99 2500 4wd 6.5 Suburban?

My trans is on the way out, and can't do a re-manned right now. Found one with 101K to replace mine with 186K.

Any suggestions are greatly appreciated!

Thanks
