Anton,
I am having the same problem; TCI shift kit tho, and a 87 Astro 700r4 behind a 94 iron head LT1.
Last time I did this it rained ATF for days.
I had 2 balls left over too. I read the directions several times also, and thought I was very for sure that it was installed correctly just like you.
I suppose I will be under the van with raining ATF again.
I hope that is the problem.
