i think theyre like $900 in jegs for a mild one, but they can cost over $2000 depending on what parts are used in them. like buck4more said, you dont want to use a 1.82 glide... the only thing that is good on those is the case and pump (same as a 1.76). the input shafts are like tooth picks. Id go with used 1.76 glide, then buy a hardened input shaft, stator shaft, and a master rebuild kit. Get the TSR powerglide rebuild manual and have at it. theyre really easy to rebuild and require a minimal amount of tools, especially if you wont be installing a trans-brake. You can probably get away with only having around $300 dollars in it, plus the cost of the used powerglide. Plus youll learn how to build your own transmission, that is priceless
