2003 Chrysler Town and Country Clicking noise on decelerati

Noises problem
2003 Chrysler Town and Country 6 cyl Automatic 79.900 miles

Clicking noise started in front end of vehicle noticed during deceleration above 25 mph approx. Took to first dealer, said need new transmission and CV jts.
Took for second opinion, tested for transmission, said need new transmission. It sounded to be like something was just "loose" in transmission to me.
Transmission still shifted smoothly, no jerking at all. Had transmission fluid changed 2 mths. Prior to these problems. Had transmission tested and replaced by AAMCO. Got vehicle back, still makes same clicking noise as before transmission replaced. Took to have CV jts. Flixed and told they were fine by different dealer. This noise happens without braking. When accelerating noise is not there until you let off the gas. Any ideas? My stepdad is a mechanic, has riden in the van with me, an does not know what the sound is but believes it is from transmission.
