    so the other day it was cold cold out and on the highway it was so windy that no one was going over 40-50mph. My truck shifted into 2nd and I never feel it shift, then it felt it immediately shifted again. Thought that was odd and thought nothing of it. A few minutes later I went to pass someone and hit the gas and the truck did nothing, didn’t rev/didn’t shift just the same speed so I tried again and it rev’d went and then the rpms dropped again. So I’m thinking it’s so windy that it’s fooling the electrons somehow? But the bad news was it wasn’t that bad today and it was doing it again, it seems to be at higher speeds but something is off. I have no check engin or codes? Anyone think of anything I can get in front of? The trucks info.

    -2007 Tundra Limited supercharged
    -Bully dog gt: performance mode
    -TRD everything that can be
    -Run only 93+ gas
    -Kissing the 100k mile mark
    -*gotten a crankshaft code on 2 occasion and cleaned it with some MAF cleaner and worked after that
    -set up appointment with stealership for Tuesday to have the 100k transmission flush/gasket also new plugs/filter/Borla Muffler installed to replace huge Trd 2nd gen muffler
    -drove the previous days leading up to this with the LSD off?

    Any hints or help to get a head of the problem would be great appreciated cause I don’t have down days if whatever fails soon

    Interesting. Mine shifts hard when cold obviously but every once in awhile my 1st to 2nd is kinda harsh but not worried about that it's the most used. I also notice my truck shifts quickly. My guess would be the programmer. Maybe take it off and see? Is it almost like limp mode no rev past certain rpm?

    Humm, I’ll have to check to see if it revs and to what rpm
