I have a 2001 Dodge Caravan SE 2.4L 4 cylinder motor. I had the transmission flushed almost 2 years ago and since then have put 12,000 plus miles on it. All I know is you are suppost to check the transmission fluid while the car is running and idling at normal temps. When between warm and hot you are not suppost to add any fluid. I also know that it is very critical not to add to much transmission fluid. However this is my problem. While running and idling in park at normal operating temperature I pull the transmission dip stick out and dont see anything on it at all (no fluid). When I shut the motor down and pull the transmission dip stick out it is just barely over the add line. Finally if I let it sit over night and check the transmission fluid level when the motor is cold then the dipstick has brown/orange fluid on it??? How do I change transmission fluid? Can I do it myself? Do I need a shop to do it? Could I add fluid instead of flushing and replacing?
