I'm new to this forum, so thanks in advance for any help.

I have a 2003 Z71. It now has about 14000 miles on it. The clunking problem started at about 3000 miles/9 months ago and was limited to shifts between 1st and 2nd gear. It has been back to the dealer 7 times for this problem.

The tranny was reporgrammed, a nickle plated slip yoke was installed, controls on the 4x4 were replaced, a jumper wire was added to the alternator to reduce electronic noise and now I have a more pronounced clunk between 1 and 2, and it's starting to clunk between all gears, including going into reverse.

After trying all of this, GM TAC is telling my mechanic that this is "normal" and no repair should be attempted. Sounds to me like an engineering problem that they don't want to fess up to. I have a difficult time believing that anything considered normal is getting louder and much more frequent, and the clunk that it's making now has to be doing damage.

I've tried to sell the truck, but to two guys that test drove it both said is sounds like it have a U-joint out or it was abused! (It's never been off the road.) It has now gotten to the point where I drive my '95 Buick instead of my new truck. It's driving me nuts.

Short of hiring a lawer, is there any way of actully fixing this problem?
