Helpful Expert Reply:
There were 3 possible transmissions that could be on your 2000 Dodge Caravan. The 41TE is a 4-speed and its return line is the one in the front of the transmission. The A31TH is a 3-speed and its return line is the one on the top of the transmission.
There is another 3-speed, A670, but I cannot find the information on which line is its return line.
If you are not sure which transmission you have you can start up the van, keep your foot on the brake, and shift into drive for about 15 seconds or so. Put it back in park and then you can feel each transmission line. One should be noticeably warmer. The cooler one is the return line.
You can follow the return line from the transmission to the radiator to determine which line is for the transmission and which are for coolant.
