Right.....he's aware of that difference. Maybe they're actually made for the manuals, and not the autos. I don't know what the deal is, but he insists they'll work. I think I'd have him install them into a lightly used manual V6 transfer case, and purchase the whole thing. Then, I'd send my t-case back to him for core. Then if he's wrong, he'll know before he ships it out, and could eat it. Don't ask me.....I just know I've mentioned it twice on the phone with him and he's said they would work. I know he's extremely knowledgeable on Samurai's and Sidekicks/Trackers. Maybe somebody who knows more than me should give him a call and mention that they've been thinking about getting the gears for their 5 speed GV.
