    Do you mean a bone-stock 700R4 from the factory, or a built aftermarket unit?

    GM used lots of penny-pinching stamped partz. The aftermarket has developed heavy duty, higher capacity, yadda yadda... What transcase are u using? I personally like them, but most don't. Maybe I'm lucky, so far. Check eBay, lotsa talk. Or transmissionhead.com.
    Any place with un-biased reviews?

    Depends on what you plan to do with it. They can be built to live behind 600HP or so in a light drag car. But when I asked the folks at www.bowtieoverdrives.com about putting a built 700R4 into a 6500 pound, 454-powered Suburban, and towing a 5K+ pound camping trailer behind it, they recommended the 4L80E instead.

    Not much...I dont like those damn things. I dont know how much horsepower they can take, but even a built 700 I wouldnt want to put behind anything other than a very very tame small block. With tires no biger than 35-37, with the right gearing of course. I know quite a few people around here run decent sized tires with 5.13's or lower and seem to not have a problem with them. I have personally taken care of 3, and as a result I am very leary of them. I have a built jet 400 with a full manual valve body in my truck now and I still have a little nervousness towards it only because its a auto.
