Clunk during shifting????

[Hammer450R]

Is this a normal thing? happens most from 2nd to 3rd gear shift and driving nicely. If i jump on it it doesnt do it. Anyone having same sounds?
I just had 2 U joints replaced at the dealer recently also.

I have a similar sound, had the tranny, transfer case, u-joints, motor mount all checked and they were not the culprit. I was told it might be the ABS pump, will have it checked at a later date.

Mine does it also, same 2-3 shift, but my trans. is far from stock.

My 2010 LTZ does it, only if I accelerate slowly, then let off the gas to coast to a stop sign, etc.

Mine does it too and it drives me NUTS!! Seems like it does it all the time now. I have read somewhere that GM calls it a normal condition. I think its BS! Why are the other shifts smooth as silk? Anybody have any remedies?

If i remember right my 99 Hoe did the same thing.

Landshark,

The best way to find out if there is indeed an issue with your vehicle is to take it to the dealership. Have you had your vehicle in for a diagnosis?



Thank you!

For alot of you guys it might be U joints, they replaced 2 of mine front and rear drive shafts at 75,000 miles. Told me they are having a run on u-joints on post 07 models. Mine is going in Tues for possibly more.

What was the outcome with the last visit, Hammer? Thanks.
