What causes my 2006 rendezvous cxl awd to make a loud clunking noise when I put it in gear from the park position

The Clunk could be many things so a bit more detective work is needed. When Exactly does it 'Clunk''? is it any of the following?
-As you 'rev' the engine in neutral?
-As you put it in gear?
-As you change gear?
-As you start to pull away from a stop?
-As you apply the Brakes?
-As you release the park brake?
-As you turn into tighter corners and junctions?
Please comment below with more information and I'll see if I can help you more.

service the transmission
new oil does wonders

It may be possible the starter was replaced at some point and someone forgot to install the start shim or shims. Also, check the charging system because you may have a bad alternator.

Our Rendezvous groans, too. Our mechanic told us it was NOT a wheel bearing, but the rear differential. They recommended that we take it to a reputable transmission garage for service.

The humming noise could be a wheel bearing, as for the clunking noise does it relate to the brakes at all? If it is with the brakes could be caliper/pad clip maybe the problem. If not brake related possibly it could be a motor mount.

Is it a metal shaft? When you put it in drive does it make any noise? Does the speedometer move? Does it make a loud clicking sound when you put it back in Park?

i would have this fix asap ,could cause internal transm. damage!

I believe there is a recall for that feature. but i am not 100% sure. it was recalled on 2004 rendezvous
