^^ ya tell me about it. tray cost more then the SC lol. find out later what the deler has to say. And then wait to see what Sam says he has uphill sleeve for the tranny. But you would know more bout that then me. I know that the tray was going to be a weak point but i did not figure it would fail like this.

If thats the worst of it than I'm sure it will be an easy fix. You dont hear it at idle, or under any load above 30-40% throttle...its 100% during cruising. I dont count decel or in between shifts because thats how its suppose to work.

Do the GTM kits come with that plastic Bosch BPV? I used to run that stock in my old Saab 900 and once I got up to 360hp and 20+psi, it would flutter because the internal spring was simply not up to the task of holding back that boost or releasing it effectively.

I would definately move onto another BPV; I have had great experience with Forge personally.

Have you seen the GTM vids that show what the flutter sounds like? Did the flutter on your old Saab sound similar?

I think you missed my joke there. As at as he auto trans, that is not eve close to my area of expertise. Sam does have a guy for that, and he is one of the best.
