[sm=americanasmiley.gif]Hello, i have a chevy tahoe LT premium 2002 with 64000 miles and there are a noise in the gear box when I go from P to D, from P to R or D to R and even when i drive and the gear change is doing a clack...In the garage, they said me that it was normal, but for me it s negative. If somebody has a idear, thank you very much.

Sounds like U-joints if it does it when you are stopped. If it is doing it also during upshifts & downshifts then that sounds internal.
