2003 Dodge Neon Repair Question
Transmission fluid in collant resovior
Your vehicle is equipped with a transmission cooler which shares the same coolant as the engine to help keep the automatic transmission assembly cooled off. There is a fault with the tranny cooler, cooler line or tranny itself causing the tranny fluid to leak into the cooling system.

change the radiator the tank is cracked.
Where is it located at. I'm used to the line connecting into the radiator itself

look at the bottom of radiator the lines should connect there.
Here's a diagram...
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells burned, and is contaminated with metal or friction material particles, a complete transaxle recondition is probably required. Be sure to examine the fluid on the dipstick closely. If there is any doubt about its condition, drain out a sample for a double check. Mopar® ATF+4 (Automatic Transmission Fluid) when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. ATF+4 also has a unique odor that may change with age. Consequently, odor and color cannot be used to indicate the fluid condition or the need for a fluid change. After the fluid has been checked, seat the dipstick fully to seal out water and dirt. OIL COOLER FLUSHING
NOTE: Manufacturer recommends Cooler Flusher (6906) as the only suitable procedure for flushing oil cooler. Use only petroleum-based flushing solvents. Do not use solvents containing acids, water, gasoline or any other corrosive liquids.
NOTE: Always reverse flush when flushing oil cooler and lines.
1.Note oil cooler supply and return lines. See Fig. 6. Remove cover plate filler plug on cooler flusher. Fill reservoir 1/2 to 3/4 full of fresh flushing solution. 2.Reinstall filler plug. Ensure pump power switch is in OFF position. Connect Red alligator clip to battery positive, and Black alligator clip to chassis ground. Disconnect oil cooler lines at transaxle. 3.Connect Blue pressure line to outlet oil cooler line. Connect Clear return line to inlet oil cooler line. Turn pump on and flush oil cooler and lines for 3 minutes. 4.Monitor pressure reading and Clear return line. Check equipment manufacturers instructions for pressure specifications. If solvent flow is intermittent or exceeds specified pressure, replace oil cooler(s). 5.Turn pump off. Disconnect Clear suction line from reservoir at cover plate. Turn pump on for 30 seconds to purge flushing solution from oil cooler lines. Turn pump off. 6.Place Clear suction line into a one qt. (.95L) container filled with ATF. Turn pump on until all fluid is removed from container. This removes remaining flushing solvent from oil cooler lines. Turn pump off. 7.Disconnect alligator clips from battery and ground. Remove flushing adapters from oil cooler lines. Reconnect oil cooler lines. Fill transaxle with appropriate fluid to proper level. See CHECKING FLUID LEVELS.

OIL COOLER FLOW CHECK
1.With transaxle fluid filled to proper level, disconnect oil cooler return line at transaxle. See Fig. 6. Place container under oil cooler return line.
CAUTION:Do not obtain more than one quart of fluid, or transaxle may be damaged.
2.Apply parking brake. Start engine and allow it to idle. Place gearshift lever in Neutral. Check fluid flow from oil cooler return line. 3.If fluid flow is consistent and takes 20 seconds or less to obtain one quart, oil pump volume and oil cooler flow are okay. If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, disconnect oil cooler inlet line. Refill transaxle to proper level and recheck flow. 4.If fluid flow is intermittent or takes more than 20 seconds to obtain one quart, check line pressure. See PERFORMANCE TESTS in appropriate DIAGNOSIS article. If fluid flow is consistent and takes 20 seconds or less to obtain one quart, replace oil cooler. Reconnect oil cooler lines. Fill transaxle with appropriate fluid to proper level. See CHECKING FLUID LEVELS.
