8600 gvw for a 700r4 input torque 350 gearbox torque 650
15000 gvw for a 4l80e input torque 440 gearbox torque 885

i say it again. 650 for a used 4l80e, 800 for a controller and you have 1450 in a tranny.

or, buy a uses 700 for 600 and spend at LEAST 1000 "beefing it up.

remember the 4l80e torque converter bolts up to the GM stuff, unlike a 700r4.

best thing? say you are out in BFE, on vacation etc.... i think it would be easier to buy/swap a 4l80e, than to find another built 700r4.
