Well you have a trany leak. Sounds like it may be at the transmission oil cooler in the radiator, you would see oil in the coolant, or trany fluid leaking from the radiator. May also be a transmission line going to the radiator.

Transmission cooler is leaking or one of the two connections to it..also check the transmission lines. Clean the area and observe the origin of the leak.. 1995- 21 years old, good possibility Radiator is DONE
