    Besides strength does a np205 have any advantages over a 203? I just picked up a free np205 and currently have a 203 in my truck. This rig will be a daily driver as well as see trail use. Also will a 205 bolt up to my 700r4? Thanks for any input.

    Strength is the biggest thing the 205 has over the 203. As far as bolting the 205 to the 700r4, it can be done if the 205 is off a th350. You will have to buy a special adapter or a different out put shaft for the 700r4.

    If you're using this for a daily driver, the 205 is a part time four wheel drive not full time like the 203. So in saying that you will get better gas milage with the 205. I was going to convert my 203 to a part time, but it would be cheaper to buy a used 205.

    So, from a search of the board I came up with A&Reds Trans Parts posted by Batmanjr. They are supposed to have the adapter plate for the 700r4 to np205 connection. But I called and they said they don't make them. Did I just talk to the wrong person? Anybody know of a different place to get this? Or does someone have one to sell?

    part time cases are better for constant on road driving, and are gear to gear driven with no chain to worry about, unlike in the 203 and 208's

    205 is best alll around case, for strenght and driveability, technially

    definitely go with 203 over a 208, however ! unless you have new chain put in first, then maybe, but dont shock drive it


    good luck

    The 205 beats the hell outta a 203 in driveline length aswell. The 203 is a good case, its just not the best.

    Except for the crappy low range... A 208 or 241 would bolt right up with the correct adapter. No changing the output shaft for the tranny. If it were me, I'd go with a 241 unless your wheeling is VERY hardcore.

    Unless you have a specific need, go with the 208.. syncronized, and you can lift it in and out with one person..Just make you get the linkage, it bolts to the floor....and the driveshafts, the front is longer, the rear shorter..(may be close with a 205 though...) /forums/images/graemlins/cool.gif

    The 203/205 takes 2 men and a boy.. it is realy, realy, realy, realy heavy....

    I don't know what a 208 and a 241 has to do with this post..........doh

    A 205 would be a good alternate to the 203, but you have got yourself an excellent opportunity here to convert over to a doubler.

    Click here for an adapter for the 700/205 combo.

    I should have looked at Advance Adapters first, they have good information there for GM trucks if anyone is interested. My first time seeing it.
    No need for a doubler. The point of my Blazer is for light trail use. There isn't anything nasty enough around that lockers won't get you out.
    Thanks for the info
