I got a used 4L60 with the complete LS1 dropout I bought to put back in my T/A. It was drained (as much as possible) but still attached to the motor with the stall and everything in tact. How many quarts do I need to buy to fill it up?

It could vary, but I would guess 5-8 qts. assuming just the pan was sucked out. I think total capacity is about 11qts.

six qts

Depending on how long was drained etc could be anywhere from 5 to 12 quarts I would add five start then add till full.

When I did my ss3600 install I stood the trans up on its tail and got everything I could out. This was after I drained the pan of its fluid also. I ended up filling it with about 9-10 qts total.

I added a tranny cooler and it feels a bit laggy on the shifts now. They say to add an extra qt. with a cooler, but is that ok to do even when the dipstick is showing full? Can you hurt the tranny by overfilling it?
