    I have an 87 k5 with a 700r4 tranny and i was wondering if i could get it out without removing the engine, and put a new one back in. i dont have a cherry picker right now and i need to swap the tranny.

    um,..YES...
    you just want to remove the tranny right?.....remove the drivesahfts, remove the transfer case..put a tranny jack, or floor jack with block of wood, under tranny, remove crossmember, unbolt tranny from motor.(belhousing) unbolt tourq convertor from flexpalte..slide tranny towards rear and down...ta da!! :D ..oh also remove speedo cable and any other cables, wires..dipstick..etc before moving tranny...removing them is easy..rebuilding them..well thats were i let someone else take over..lol...good luck

    well, i can get a brand new 700r4 for about $300. i have a bike jack, i think that would work better than a regular floor jack. but i can get to all the bolts pretty easily though, right?

    You must have strange definition of "brand new"

    yeah it should be easy to get the bolts..i highly reccomend a long extension with a "wobbly" or "u-joint" on the end, to get the bolts at the top..if you use a floor jack, just use a block of wood under the tranny pan..it dents easliy..eaither jack you use , you might want to wrap a strap around it, to make sure the tranny doesn't fall off the jack..it shouldn't if your slow and carefull..and allthough i DO NOT reccomend this..i have a couple times..not even use a jack and (bench pressed) the tranny by hand on to my stomach..but like i said I DO NOT reccomend this..they are heavy, especially when full of fuild, and even tho i haven't, i have had some friends get pinned or stuck under the tranny..

    no can't think of anything special, if possible i would put in a shift kit, not many peopel know this, but a shift kit is actually better for the tranny, less slippage on the internals...or so thats what a guy i know who owns a tranny shop told me...pesonally i run manual trannys, so don't know first hand..
