can make my 93 4l60 floor shift transfer case, work with a 06/6.0 an 4l80? or am i screwed?

 

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

 

i didn't look too much into it, but i believe i remember seeing where somebody on FSC did that

 

tht would b awesome. thanks 4 the link also. what about my harness tho? how can i make tht work? the harness is setup 4 push button 4wd.
