Last time the X was in the stealership a few months ago, they supposedly updated the tranny to the latest software. however, I have no faith in their claims and the problem is still there....and if anything its more pronounced. Is there any way to validate the software rev. without taking it back to the dealer? The update is of course NOT covered by the CPO warranty and I'm now being told if the software fix didnt correct the problem, the tranny has to be placed.....and they want $4k just for the tranny.
