older 4l80e to ls motor I work at a salvage/recycle yard and one our customers brought it in a tranny case and on the side said 4l80e. This shocked me so I asked him what it came out of and he said 95 chevy truck. Now this shocked me as well as i thought 4l80e's came with the ls motors. So after work I with through a yard and found 2 older 4l80e's in the yard one to a big block and the other to 6.5t which after searching has the same bolt pattern as sbc/bbc. How hard is it to adapt this to an ls motor? Also will the ls computer run this just with a 60e to 80e conversion wiring?
It was in my sig when I replied to this a year and a half ago. Here is the thread I was referring to.

4L80E came out in 1991. Up to 1998 they had both Speed Sensors on the Trans itself in the 2wd Models. 1999-up they had the other Speed Sensor in the Rear Diff and the Reluctor Wheel was not on the Drum.
The newer ones had a better Sprag..forgot what year exactly.

C. yes any 4l80e can work with a "gen4" aka "P59" ecu if properly wired and flashed
