None on mine either and I've put about 2000 miles on v8.02 street. The only thing I've noticed is every once in a while mine does some odd shifting between 1st and 2nd. It's only at very slow speeds and occasional. Not always.
Shifting is still way better than the v7 files I ran. I haven't ran mine in anything higher than street as of now though...... I'm trying to keep the trans in one piece. Lol.
It could very well be my trans, but it doesn't flare with v7.2 lv4, but the power difference makes it hard to judge, and I didn't do a full relearn. I'm a fan of the shifting don't get me wrong v8 is a huge upgrade from 7.2 in every area!!!
