Well, I broke down & took rig to local Jeep dealer-- mystery sound was diagnosed as "Faulty torque converter & front pump for Transmission". Here I thought the AW-4 was indestructible! I even paid for a pricey BG trans. flush a few years back...

I knew I was in trouble when tech quoted a $1000 for the TC alone-- wouldn't even give me a estimate for job-- "All day" repair I was told...

My main mechanic won't tackle it either-- should I try the local chain transmission shop for repair? I'm at a loss.

TIA for any suggestions

Find a good trans shop. Ask around, they're out there. Those japaneese
converters are always over $900. at the dealer. Your looking at more
than just a pump and converter if in fact the pump AND converter are
faulty.

What's the mystery sound? The Jeep dealer may be taking you for a ride and it could be as simple as a cracked flex plate (pretty common). You can pickup a used tranny with t/c pretty cheap at a local salvage yard. I got a 99 AW with 95k miles for $50.

A rythmic d-d-d-d-d-d-d from bellhousing when in gear; shifts fine & plenty of power. Noise stops in Park.

I'm thinking you should pull the inspection cover off the front of the bellhousing and check the torque converter bolts. Use a screwdriver to gently pry on the flexplate while looking up near the center for cracks.

X2 I would suspect flex plate bolts backing out.
If not checked soon - destruction to follow.

As stated, DC mechanic wanted to replace TC & front pump--what would be a reasonable estimate for TC bolt tighten?

First, find out if that's the problem. It's pretty easy to diagnose yourself with a few hand tools and crawling under there in the driveway. I hope this doesn't sound rude, but how mechanicly inclined are you? Perhaps a smaller, independent shop that's familiar with Jeeps would be more inclined to actually look at it instead if giving a wild diagnosis based on the sound.

Look in the Classifieds on this and other Jeep forums for a good used AW4 usually around $200 for trans and converter. Even with the shipping you will come out ahead over the DC $1000 price. Any good mechanics shop will exchange it with your current trans for around $200 to 300. Half day job.
A phone call to my local AAMCO says $250 if I provide the trans, converter and fluid. See what kind of quotes you get, they may varie by geographic location and mechanics prices.
