[QUOTE=Is this what your feeling Alton ?

Does your '11 with the TVS 1900 have a 6 speed and if so how is it doing ?[/QUOTE]

yep it's the one im talking about...
that's basically what I feel...I thought someone hit me from behind when I released the brakes to pull forward...I didn't think about the tow/haul...i'll drive it again today and see if maybe I accidently pushed the button

I get a 2-3 flair shift from time to time. Unusually it's almost always the first 2-3 shift of a drive cycle and usually occurs after parking on a decline and still warm from the previous drive.

Was this recall /notice just for the 11' model ?

Anyway yeah I bet you just felt the harsh shift back into 1st gear in tow- haul mode. It surprised me when I first felt it also , I never thought about the truck starting off and returning to 2nd gear under easy driving in normal mode ,

Thanks SCREAMINGL for the info !

I think we may just not be used to how the 6 speed shifts/ acts , I'm used to my 80E in my truck and my Van . Prob gonna be while of driving before I get the "feel" of the 6sp.

What you Think Bud ?
