I appreciate threads like this. Hoping I won't need the info for a long time. So far, with about 168k miles, I can only remember two odd occurrences: while stopped at a traffic light, it felt like it shifted from second to first after I was stopped. I've serviced the transmission twice: pan/filter/fluid at 118k miles and just fluid at 167k miles. Adaptations reset both times and no flushing. Got a DDE tune around 100k miles. I've no complaints so far. Started calling around to see if anyone would be able/want to replace the bridge seals, Mechatronics sleeve, or swap out a valve body and have been told flatly 'no' every time. No one even wants to replace/swap a whole transmission. I plan to keep looking and just enjoy driving it. It's still a nice truck that gets compliments today and I know two people who would give me a good amount of money for it if I wanted to sell.
