727 question

I just had my 727 rebuilt and the builder told me put a 1/2 quart in the converter and 3 Quarts in the tranny. When you run it start filling it up with at least 6 more Qts. and check when hot. You're running the front pump dry on the trans and who knows what else might be messed up. I hope it was minimal damage but you won't know till it comes apart.
