My 2008 MKX 81k miles is now experiencing the ODO DATA ERROR issue. Scouring the internet turns up the TSS and OSS being the likely problems, but this is the first thread I've found where replacing them did not help. So now I am wondering if in the event those are not the issues, how deep of a rabbit hole could be it figuring out the problem? Also, how far is it acceptable to drive in the "high gear" thing it currently seems to be in? I got off the road, into a parking lot and it has been sitting there overnight, but might have a go at limping it to the dealership about five miles away. If that's too far, there's an independant mechanic I've used before, only one block away.
