Bucking when going slow
Have just about 1,600 miles on tuck born on 12/14/11. Love it, but..
When going slow in subdivision I am getting some hesitation/bucking when going in the upper 20s/lower 30s. When I feel it I look down and I am usually in 3rd.
Is this the transmissible thing? When it happened Sunday it felt like it was going to die. If I start off with a quicker start (to get to highway speed) it shifts fine.
Any thoughts? It just started the last few weekends......

Mine has always been like that....
When driving (almost any speed):
-If I roll on the throttle;instead of down shifting it just bucks like crazy and makes a slapping sound from the trans.
-If I get hard on the throttle it down shifts a couple of gears and takes off like a rocket.
No in between.
BUT, I am lacking a transmission TSB that replaces some solenoids etc...so maybe it's just me.
Thanks

IMHO, (and likely in the name of fuel economy) the trans is always in at least one or 2 gears too high for driving around town / driving slow. I believe that is why mine alwasy feels sluggish and bucks when driving slow.
To test my theory, try driving in T/H, it should go away. But then you are stuck with those nasty hard down shift that smack your forehead into the windshield

Really, only Darren?
When this happens and you press the pedal it stutters. I am not sure it is a transmission issue or something else. When it comes out of it it drives fine. It's only on slow accelerations to a slow spped (like in a 30 mph zone)
Guess I should stay out of those.
I am tempted to ask the dealer to reset the adaptive learning thing. Will they do that by just me asking?

One other note, I smell the burnt smell when I got out so I think it was doing a regen. Don't know if that was a factor or not..................

2400 miles. No hesitation, no bucking, no 49mph death wobble, HPFP works great. I can't complain!

Mine does the same. Usually durring the first time in the morning i'm leaving the driveway under slow acceleration, seems to be an engine issue. After the first mile it seems to disappear. Stopped at the dealer to check if there was any issues being brought up by owners or ary recalls or service bulletins. They check while I watched and the service manger couldn't find anything. SO, if anyone comes up with any information on this annoying problem, please let me know. O ya. 18000 miles on it.

Driving slower in town or when the engine is cold and I take it easy on it, my truck does the same thing, hard shifts, seems like the truck isn't sure of what gear to be in. Even coming into town slowing down 6th to 5th it shifts really werid and the shudders. When I drive it harder it seems to shift way better. My truck also does the horrible shifts from 2nd to 3rd, seems worse when its cold.
