Is anyone having a vibration during the up shift fron 1st to 2nd that you can feel in the pedal and here a groning from the tranny, this only happens at a slow speed, if you are on it it shifts fine

 

Yes I have it. Going to the dealers on Dec 10th

 

The 04.5 2500 auto 4x4 I traded in had just the "buzzy" feeling in the pedal, shifting from 1st to 2nd just like you said. I could not hear any noises when this happened. I never took it in for that, as it was so mild I barely noticed it. It might have gotten worse if I had kept the truck, as it only had 2600 miles on it when I traded it in on my 3500 dually.

 

i took mine to the dealer, and they said they could not feel it, but he did adjust a cable that they tought would help, but now it clunks when it down shifts from 2nd to 1st if you let up on the throttle fast and still has the first problem.

you will have to let me know what you dealer finds, I am going to a different dealer to try again
