Man I really hate tonhear that! I unfortunately don't have any ideas about what could be wrong. Have you called sun coast yet? I'm sure you are well aware of their warranty policy... It would be a pain to pull the tranny and ship it to them to be fixed, but at least the parts would be free. Keep us updated

Well, it hate to tell you this, but I bet you smoked your converter. I did the same thing in my Dodge with my ATS tranny. You held pressure until you stopped, then you couldn't get enough pressure to build up to move again.

Good Luck,
