I have an ecswb 03 GMC. It has developed the anoying clunk in the driveline over the past 1,000 miles or so. Every time you give it gas or when you are driving slow it will clunk on the 1 to 2 shift. Do they have a fix for it yet? Or is it going to be one of those things the dealer "repaires" once a year until my warranty runs out?

 

a clunk with the 3-2 shift is internal tranny noise. gm says its normal............hope i got that right

the rest of the clunk is most likely the tailshaft slip-yoke... go back and bitch until you get a nickle coated one.

i just developed the slip yoke clunk on my 03 damnit. im gonna go bitch and bitch pretty soon

 

Bitching always seems to work for me, or threatening to kick their asses until they call the cops on you
