I can handle the milling part... thanks for the heads up!

You obviously have better luck than me... My truck has 7000 miles on it and Black Bear has tuned on the trans for months and we can't get it to shift firm at all. Justin actually has told me that my tune has almost twice the pressures that all of his other tuned transmissions have and that the customers complain that there trans shifted like it was going to break a u-joint. So I think the valve body has a stuck valve or one of the apply pistons are cracked, or one of the solenoid laminates are torn.

I have spent a really long time fine tuning my 6L tune. I feel I got it to the point where its spot on. if anyone is interested I do not mind sharing.
