I'm working on a deal for an 89 np241 tcase. The nice fellow I'm talking with knows much about the 241 he obtained, except what tranny it's fit for. He can't tell me if it is definately setup for a 700r4 or not, but he does have the proper adapter. I want to swap this inot my 84 Jimmy if the deal goes through, but need to know first if it will bolt to my 700. Is there a definate mark or "thing" I can tell him to look for to verify that the 241 he has is set up to work with a 700? I'm excited at this oppurtunity to get a 241 but want to make sure everything is moot before tearing the truck apart. Also, can this swap be done in a day?
