Issues Encountered:
- I've always been disappointed with the shifting strategy of this transmission. It's not as smooth shifting through 3-7 as i'd expect from a new vehicle. I've never liked that in highway traffic conditions it either takes too long to downshift in the normal drive modes, or drops 3-4 gears and gives you all of it. It's like there's no in-between. I prefer the RPM range and shift feel that the sport mode provides, but in my opinion it holds a gear for far too long after you're done accelerating before it will upshift back to a cruising gear. Picture you're on a country 2 lane road and you have an opportunity to pass a car. Say the truck is going 55mph in 7th gear, it'll downshift to 4th or 5th to pass, but then hold that gear forever after you're back to cruising before it will upshift back to where you were.
- I was hoping that a tune would fix the general clunkiness and eliminate the 1-3 skip shift. In my experience, the Livernois tune has made the truck much faster, but it still has every shifting gremlin that it had from new.
- The only solution i've found that makes the transmission smooth as silk is to do a trans re-learn/clear adaptive tables in ForScan. My problem is that even with the adaptive learning tables turned off the truck will still eventually creep back to harsher shifting than i'd prefer in the mid range gears. In order to make the truck drive what in my opinion is acceptably, I have to do a trans reset in Forscan about every 500 miles.
