Auto trans a bit sluggish and seems to make a whining? sound
Happens only when i first start out, and just when i come to a full stop. sort of like winding up and winding down. almost sounds like what public buses sound like. my suspicion is that maybe the low (1st) gear may be slowly going??

When you hear it winning like that its usely because the trans. filter is resticting the flow of oil thru it, because its getting pluged up and the oil is wore out, might be a good time to have trans. serviced, Before it really cost you$$$$.

You need fuel and spark to run. Vehicle is about the age that fuel pump goes. Have someone get in vehicle and close door (so key chime sound not interfering) turn key to on - but not all the way to start and while they do that stand behind, or next to, vehicle and listen near gas fill door, or even bend down and listen near tank, for the whine of the fuel pump. It should make a whine sound for a few seconds and then turn off when full pressure reached. If no whine, or whine never stops - fuel pump may need to be reset or pump is bad. Check vehicle manual for fuel pump reset switch (usually in passenger foot well or trunk area) and try that button. If fuel pump starts working after reset try starting. If pump is working but still no start then pull a spark plug and ground the base of it to engine and have someone crank it to see if spark is happening at end of plug. Those are first steps to see if you have fuel and spark.
Alternators can sometimes whine when start up on a cold morning, they run on full load till they get the battery back up to full charge. When the whining stops, switch on electrical equipment (Headlights, fan full boost, heated rear window) if the whining starts again its the alternator.
Manually shift thru all gears up & down the scale. Try adding Motorcraft Additive Friction Modifier, available from Ford parts dept. This REALLY STINKS!!! Don't get any on you. Pour into trans fluid. Drive a few miles shifting manually thruthe gears, then do a normal start stop drive several times. This will luburcate trans, normally used for differential but has worked in automatic transmissions of all makes for years. Otherwise mechanical problem for transmission repair facility.
Maybe a stretched transfer case chain.
I wouldn't rule out some trans issues
Got the correct fluid in transfer or proper level
The clunk sounds like ,U-joints
Check all the mounts on everything,trans, transfer.etc
If you have a warranty from your dealer, you paid for it, or whether it came with it, it doesn't matter, you MAKE them honor it. Take it back there, and MAKE THEM FIX IT! This shouldn't be your problem if you have a warranty. If they aren't honoring it, threaten them with the BBB or court. They will shape up. I would say power steering pump.First check to make sure there is fluid in the reserve tank and at the proper level if not top it off and whine should stop.If level is correct then maybe try flushing with fresh fluid. 3.8L engine the power steering fluid was never toped/checked.. because it is a pain in the *** to get at (behind the hot as hell alternator), so it probably ran dry, top it up is probably all you have to do.. if the whining presists then you will have to try and bleed the air out by jacking it up, engine off, turn the wheel one side to the other about 25 times.. if that dont quiet it up then you will have to replace the power steering pump. Power steering pump / fluid level is not hard to check - it is located below the alternator on the passenger side of the engine bay. You need a light to see it. You can get your hand down from the top of the engine to loosen and remove the cap/dipstick.

If the trans has a whine and shifts a little hard then you need to take if to a service center and have the trans flush and filter changed this might correct the problem. But if you have never had the trans fluid change and have 100,000 on it trans might be going bad. Trans fluid and filter should be changed every 40,000 miles.
