You may have a bad fuel pump. Have it checked at an auto shop.

check the air filter, it may be blocked

The transmission must be removed and torn down to inspect for damaged parts, you most certainly will need to have it exchanged or rebuilt.

could be the crank position sensor.

so it idles fine as long as it is in park. when you shift it into gear it stalls?

Does it feel like if you had a manual transmission and you let out the clutch with your foot on the brake?

if you are in a place you can do this safely without hitting anything try starting it while the transmission is in neutral. After it starts put it into either drive or reverse with your foot off the brake. Does it start to move, then the rpms start to drop fast and then stall?

Again if you can do this in a safe place what happens if you do the above and as soon as it goes into gear you give it a little gas? Will it move and stay running until you come to a stop? If yes the torque converter is locked.

Unfortunately from the description of the fluid and this symptom your likely looking at replacing the transmission.

did you clean the throttle body? if not clean it. its the number one cause of low engine speed stalling

My 98 plymouth grand voyager was having same problem changed several sensors before finding a very dirty crankshaft position sensor. After removing and cleaning my problem has disappeared. Youtube has a video on replacing this sensor. Careful when reinstalling. Position is critical to far in and hits flywheel. too far out and will not start.

Then you might want to idle the low idle speed up a half a turm to see if that sovles the problem.

are you usually on a hill when this happens? i had the same problem with mine but it would usually do it when i was going up hill. try getting your O2 sensor replaced... have them check your fuel pressure. could be your fuel pump. hope this helps
