4l80 swap

Linkage is different, trans cooler lines hook up differently, and a 94 trans doesn't have the bosses in the case for your nuetral safety backup switch.
 
You will need to swap the manual shift shaft in the trans, fab a bracket to mount the nuetral safety backup switch to, cut your trans cooler lines, and make adapters to adapt down your 3/8" quick connect lines to the 5/16" flared fitting lines of the 94.

Do I need the long shaft for the neutral safety switch be cut I can just put the switch in park permanently or do I need the length to connect the shifter?Thanx
 
Both, the 94 uses a short shaft and points up, the 95+ is longer to allow the nsbu to mount and so the shift cable can connect because the point down which makes them need the longer arm to clear the pan rail. I wouldn't mess with putting a 96 or older into a 97+ myself. You can use any 4l80e from 97 on up to 09 in yours, and can pick up used pullouts on Craigslist pretty cheap normally.
