Hi, guys! Tell me, is there an upgrade for 6AT?
how safe can hold the power 6AT? I have upgrade RB turbo, and I'm afraid to raise the pressure above 19psi!
Will the engine live safely?

I'm in the same situation. Level 10 sells rebuild kits for this platform. I wouldn't beat on it daily at 19 psi but keep the boost down for regular driving and crank it for race days. One way or another you will need a rebuilt transmission... It's just a matter of time

Level10 for sure, just be aware to get the most out of it you really need to have them someone flash some of the trans parameters and Level10 needs the car for that. Based on some hints from Shiv, he may have some info on that later when he releases more info on his AT Single turbo car.

Also Level10 recommended to me NOT to build the trans first, but to beat on the stock unit and when it gives you trouble then work on it

I have done the complete level 10 rebuild and very happy with it so far.
Just destroy yours first, it will be obvious when the trans starts going.

level 10 is a joke, I have tried to reach them numerous time over email but communication end every time I ask to ship rebuild kit/upgraded torque converter via USPS. probably they are sort of solution for guys in the States, but not for those who live overseas..

2 questions:
  1. What does a Level 10 A/T upgrade cost?
  2. Will the driving "feel" of the car change? Kinda looking for some1 who could comment on the difference of the stock trans vs. the Level 10 rebuild and if there's a significant/noticable change in the way the trans operates

Driving and feel is the same, shifts much faster and tighter.
Price is listed on their website.

SOO quick Google search. Level 10 Transmissions is run out of Hardyston, NJ (which is about an hour out of Manhattan & 2 hours from Philadelphia). If you send them your transmission, the rebuild costs ~$4,500 or ~$6,500 from scratch, and the website says it'll take them 1-5 business days. They also offer to pick your car up & if you call you can discuss "discounts on towning, shipping & custom installation."

http://www.levelten.com/bmw_transmis...parts_s/29.htm

^^There's their link for BMW. enrita, since you're from Sweden I just wanna make sure this is the same Level 10.
