2014 AISIN 'bucking' on incline

[garrettg84]

So my new truck is bucking pretty hard at low speed headed up an incline unloaded. It seems like when when I'm crawling up a hill (in traffic) it is in 2nd gear, then slams 1st causes the truck to lurch to a near stop then surge forwards back up to 2nd when ever I am coasting and hit the gas again. It is a single buck every time I touch the gas, not a vibration or shudder, just one single massive buck. Anyone else experienced this?


It doesn't seem to do and craziness that on level ground or on a downhill.

I think we have (made you look at each other with a wtf look on our faces), but after a couple of software updates wasn't an issue anymore worth mentioning. Sounds like your gears are overlapping to much. There's a way they can force a relearn/clear on these I think, since they they do adjust for driving habits. See if it does it in Tow/haul, with or without the exaust brake on. and roll by your dealership with the info......

My 13 had a very harsh 2-1 downshift that was fixed with a software update at the dealer.
