Do u have the version of software for the pcm or what exactly their calling this upgrade? Like whats missing that maybe i should have had or need loaded with the software..

 

They uploaded it with the Tech II, so I have no idea what it was. I have the paperwork somewhere...but no idea where it is right now. Best just to go in, they will have all the updates/latest updates there and can upload them to your truck. There may even be more updates released since I was in. I had the same thing happen to me on a trip to Phoenix (missed shift w/over-rev), but since the update, no issues (15K miles later).

 

do u think re-programming all my info with the hypertech programmer could fix this issue too? say dealer has it on "record" but still doesnt fix it, would this be another option? anyone? if so what should the specs be? thx again
