Ok I bought a LS2 and what I think is a 4l80. I obviously want to match them up, but was told I have to have the 4l80e. Now after running number with no luck an searching to no avail. Do they look different than the other? Do I have to have the 4l80e to run my LS2? My 4l80 does have a 6 hole stall converter if that helps. Any info???
