Thank you! I think this is what they did to my truck – not perfect, but an immediate and obvious improvement.Hi there. New to the boards. The harsh 1-3 upshifts/ poor gas electric transition has been bugging me. Ran across this recent TSB to fix the problem. Wanted to get this out there for those that are effected by this.
It specifically says “reprogram the PCM to the latest software”, so it doesn’t sound like just a reset to me. Wouldn’t make sense that there would be a certain cutoff date either if it was just a reset. They likely began shipping them with newer software by the date specified.Where did you get that information from? I need something to send to my dealer. I just got my truck back from them for these exact issues.
Good morning! Could you please send over a private message with your VIN? I would like to see what I can do to assist with these shifting issues your truck is experiencing.I have noticed my shifting get noticeably clunkier - now at 12 k miles. Thank you for sharing this, hope this is the ticket.
Question - why cannot this be an over the air update? Second, the TSB is very ambiguous about the software upgrade, it doesn't list any software versions and talks more about resetting PCM. Anyone had this done and can attest it is a real software upgrade and not just a PCM reset?
I appreciate the offer, I PM'd you the VIN.Good morning! Could you please send over a private message with your VIN? I would like to see what I can do to assist with these shifting issues your truck is experiencing.
My friend owns a shop and I was looking over TSBs because of this issue. As I find TSBs that are specific to the Powerboost I'll post them here.Where did you get that information from? I need something to send to my dealer. I just got my truck back from them for these exact issues.
How did you reset it?Mine was built 4/22 and it was terrible until I reset my trans at 4k. Having this done this week for a permanent fix, while it's in for a powertrain rattle.
He probably means he erased his adaptive tables, effectively "resetting" it to brand new with no adaptive values. It's like starting over from day 1.How did you reset it?
