Thanks for the update. Interested in your end result. My X will be getting a tranny update next time I happen by my Indy. I'm getting some vibration on slight uphill grades as I very slightly accelerate to maintain speed. Harder acceleration or deceleration makes it dissappear. I'm thinking more of a torque converter issue, but figured an update can't hurt.
