what kind of damage would happen if you overfill the tranny? I am going to drain it on a level surface, but I am just curious about what could go wrong if it were left overfilled.

Do you guys have the front end of the car 20 feet in the air?! It will be fine if it's lifted a normal amount.

There isn't really anything that will be damaged unless it was really overfull. Some transmisions only take around 2.5 quarts, on the slope 3 is reasonable. With only a half quart over in there there will be no damage. It may do nothing negative at all.
Normally, if you overfill the transmission you suspend all the gears in the oil and dramatically increase drag from fluid friction. This robs you of horsepower and fuel economy (in a simplistic sense). Only the lower gears usually touch the oil. THe spinning action carries the fluid up to all the gears because it is thick and sticky and it is this property that is designed to lubricate all the rest of the gears while minimizing friction.
If it completely full then when it gets hot the fluid will expand and blow out your seals and begin to leak badly. That is the only real damage I can think of in this transmission.
Bottom line, with 3 quarts I'd not sweat it unless the thought that you might be sucking up some extra HP bothers you.

Well I drained all the fluid out of my tranny and i was actually short a Quart. But now that i think about it i remember seeing a fluid stain on the ground the day after i filled fluids. At first glance i was sure it was power steering fluid. I guess it must have been the drain plug for the tranny that was leaking. I did check and tighten everthing after i noticed the leak. But the fluid that i did drain out had some metal in it. All super super fine. It looked like wine red paint with a tiny hint of metal flake in it. I did have all new syncros, shift forks and bearings installed when i rebuilt the tranny. Im sure its just the parts getting to know eachother.
