GTX - The problem is it's a '71 Hemi trans. I understand hemi auto's holds 6 quarts but not because the pan is deeper which adds to the confusion. My pan looks exactly like the pan on my 440, no difference in depth so where does the other quart go? The extra hemi cooler doesn't look like it can carry another quart but maybe 1/2 quart? And from other posts, the dipstick is a different on a 70-71 hemi vs 67-69. If I could empty the entire system, then add 6 quarts, then mark the stick wherever the level is would solve the problem but getting everything out sounds like a lot of work.
