I bought a used 2013 with 17,000 miles on it back in August of 2016 and it now has 23,000 on it and hadn't had any problems until March of this year. The first time I was heading home from work and stopped at a stop sign went to take off and it would barely start gaining speed the wrench light came on speedo didn't work and everything else was dashed out. I limped it home as I was only like a 1/4 mile from home, turned it off and back on and it seemed to be fine. I didn't think nothing of it til a month later in April when it acted up again twice in the same week. This time I did not get the wrench but I noticed it was shifting from 1st to 5th after coming to a stop. Tried putting it in manual and shifting that wouldn't work. I noticed I could clear the symptoms with cycling the key. I took it to the dealer a few days later and they keep it 4 or 5 days and said that it would not duplicate the symptoms and it had no error codes. I bought the Premium ESP 60 month 48,000 mile warranty so they didn't charge me.
2 weeks ago it started doing the same thing, twice in the same week wouldn't throw the wrench light and would clear with a key cycle. Well last night it done it but this time it wouldn't clear with turning it off and pulling the key tried it twice even waited for the screens to go off. Kept shifting from 1st to 5th so decided to try manual and it lets me keep it in 1st gear to get going then I try to shift to 2nd and does nothing and try again it goes to 3rd and the wrench light comes on goes off and everything is dashed out again and the speedo doesn't work so I limp it down to a red light put it in Drive and it takes off from a stop in 3rd shifts to 4th and 5th like it should. I notice it won't shift in 6th gear. I slow down for a stop sign and it down shifts to 3rd like it should but won't go to 2nd or 1st so I easily take my time to get it about 10 miles down the road to the dealer only having 3rd, 4th and 5th.
I get it to the dealer about 7:20 last night and they close at 8. I don't turn it off because I want someone to see it. I tell him that I've brought it in before and tell him about the TSB and he rights it up gets in it, and pulls it in and turns it off.
I'm afraid that once they turn it back on it will clear itself again and not be able to see any codes etc. Also I think my truck isn't showing up for this TSB because it says for vehicles manufactured on or before April 8th 2013 and my truck was made in June of 2013.
Sorry for the long post just wanted to go in detail what it's doing and it seems like this TSB would fix it.
Any help would be appreciated.
Thanks,
