Shift Between 2 And 3

[KShepJr]

On my 07 NBS Crew Cab, After running the truck hard for the first time (I have approx 6k on the new truck) I now have a slight hesitation when the truck shifts from 2nd to 3rd gear. This has persisted at every shift over the last two days regardless of trans temp or RPM. Has anyone else experienced this? I thought maybe the transmission had reprogrammed itself after the strenous run but I have put on about 100 miles since at a leisurely pace. I did see that there is a TSB for something similar but that particular issue seems limited to mostly cold tranny fluid.

 

Thanks in advance

i don't know but the easy thing to do would be to take it to the dealer since im assuming it is under warranty.

use the search feature and search 2-3 shift or other similar searches. i believe there are many topics on here about it
