    I'm curious about the possibility of taking a married 241, and converting it to a divorced 241 (unless a manufacturer released a divorced 241, I couldn't find any info if that is so).

    Why? I'm considering options for my '71 K5 blazer, once I get the axle conversion finished (going from 6-lug D44/12blt to 8-lug D44/14BFF). The truck currently has a TH350/NP205 (married) but I want to ditch the automatic for a manual, and I really want overdrive - in fact, I'd really love the dual overdrives offfered by the corvette ZF or T56 transmission as I tend to cruise the interstate at 75-80. My truck isn't lifted, nor do I have plans to lift it in the future (so driveshaft angles shouldn't be an issue). I like the strength offered by the 241, and the deeper low range.

    driveshaft angle would be an issue. The T56 is a huge transmission. Add a divorced 241 behind it, you'd have a jeep sized rear driveshaft.

    NV4500 is the absolute easiest, strongest, best trans you could consider swapping IMO. And those came with 241s behind them so no worries about swapping.

    also a car tranny isnt ideal for a big heavy truck. plus they can tend to be pretty long

    I'd really like dual OD (without going to an add-on box like the american overdrives unit) so I could eventually upgrade to 4.11 or 4.56 gears for pulling real heavy **** and hard acceleration, and still get acceptable mileage. Too bad nobody's got an adapter yet to put the NV5600 behind a chevy! :(

    why do you need dual O/D for that? Single O/D will work fine for that task. Tons of stock trucks came with 4.10s and an NV4500 and had plenty of guts and did fine on mileage thanks to the O/D. You have a creeper gear on the NV4500 so the deepest gear you can use isn't necessary.

    if you're going for just street use, you don't really need the deeper low range offered by the 241. just use a dime-a-dozen divorced 205.

    EDIT: I think the new Kodiak 4500/5500 4x4 have divorced NV273 transfer cases. I forget what side the axle drop is on those, though.
