I was on some "GTS" tune at the time, but am running OEM tune now afterwards.
Mine blew up on track but I don't think it's track use that caused it. Seems that a few people had this happen across the E9x and F8x boards, but not very frequently. Another thing to watch out for is the temp/rpm sensor - replacing this will require pulling the DCT as well (location dependent, but the vast part of my cost was for labor, and not the DCT itself).
edit: I believe mikerunt had this same thing happen. Others have tracked theirs for dozens of days without problem; mine happened on the third track day.  |
Agreed- this isn't a common phenomenon, in my community losing gears under normal driving circumstance is basically unheard of. And due to the complexity & costs for repair, it's usually recommended to replace the DCT transmission altogether, rather than taking apart the valve body and fixing stuff inside.
Curious to know how'd you fix your transmission in the end?
