    :confused: ok so i have been through a couple forums, and can not get a straight answer to the ideas i have of swapping trannies. i have now a 700/208, but am going to put in a 205. now what is better? a 400 or convert to 465? this could be driven daily but is not a highway warrior. i am talking about 10 min to work , and only as long as needed to get to the woods. about 15-20 minutes. please give me any opinions or experiences you have. funds will not be an issue here, but reliability is. especially off road. :confused:

    It comes down to what you can handle. 465 is the ultimate in strength when talking light duty truck trans, but the 400 can be plenty strong as well.

    If you can handle a clutch when you wheel, then go 465. If you don't want to deal with a clutch, then go 400. That's the way I'd look at it if I were you.

    Its kind of a preferance thing.Manual guys will say 465 or nothin and most auto guys will say stay with the auto.

    I run a 350 and dual cases.If I ever swap out the 350 it will be for a 400.With an auto you can be smooth with your aplication of power.You can creep up to stuff,make contact,and gradualy add power as needed.Stopping mid climb over technical gnarly rock sections and getting going again is much easier with an auto to me.

    So what kind of wheelin ya gonna do?Why do you "need" a 205?The 3.06 first gear in your 700,and the 2.6 low range in your 208 is a great combo.

    And if ya wanna compare first gear+low range numbers :D

    465 w/205,6.55x1.96=12.838

    700 w/208,3.06x2.6x2(torque converter)=15.912

    First gear in a 350 is 2.52,in a 400 its 2.48.

    I ran a 350/208 combo for a loooong time and loved that low range :D

    If you like your auto go with a turbo 400 and a 241 case with a SYE plenty strong, the 400 can be built to be nearly bulletproof but that is not a budget mod. For ultimate strength I would say go with the 465 and an upgraded clutch. If you run the auto put a big cooler on it that will help it live a long time

    what kind of wheeling do I do? Well, I dont go rock crawling, but just about everything else. from swamps, to forest trails, to mud pits, to sand shores, to water holes, to street driving. :D i am looking for upgrades because i have trouble keeping these (700/208) parts in the truck. i have replaced both on several occasions because they were the cheapest in order to "get back into the fight" asap. :confused:

    I've had both,my personal prefferance is the 4sp.....keep you're foot off the brake,use the engine compression to slow down,no pesky lines to break or leak all over.I swapped out the auto for the 4sp. on my latest.Just a few.....:D
