I believe the spline count is different from the 93 and 06 4l60's, so you would need to change the internals. There are some other things needed to do the swap too. Check over on silveradoss.com. A bunch of guys there have done them and could help you out with lots of great info.

if'n i remember right, the NP241 has the same internals as one of the 3/4 ton floor-shift t-cases, you just have to swap the input shaft. the only thing... ain't the 4L80 a bit longer than a 4L60? you might need to lengthen your linkage

If swapping the input shaft is all that is necessary, then this thread will be of interest to mr. youngbuck: https://www.performancetrucks.net/fo...d.php?t=368971
