90 GMC 4x4 454
Newbie
I recently swapped out my 350 with a 454 in my 1990 GMC half ton 4x4. Can I swap the stock trans with the 4l80?

I know it will go in, but what all is involved?Sure, why not?
Note there are things you must do to make it work but im sure you know what they are (if you dont, speak up)
@Astro spent time putting together a 4L80E swap thread. Check it out: https://www.gmt400.com/threads/4l80-swap-tips-and-tricks.63846/I know it will go in, but what all is involved?
It basically bolts right up if you have the rear adapter with it, assuming its a 4x4. Then you need a stand alone computer to run it or you rewire it for manual shift and take 12v to it. Might need to fabricate some shifting linkage? I put a 94 454 and 4L80e in a 74 k1500, and it was really easy.I know it will go in, but what all is involved?
