Hello everyone i am from tx. I have a guestion with my 97 ford ranger. I need to know what is wrong with my truck so that i can fix it and drive but everybody is telling me different things and i am getting mad so maybe one of ya can tell me so i can get my truck on the road. The problem is that my transmission is leaking into the raditor can some one help

could be that its leaking through the coolant lines. im not sure though im not expert on this but sounds likely.

welcome,
ya it sounds like there is either a leak in the trans cooler or one of the lines/ connections.
try to find the spot where its leaking from, if you still need help to decide what it is, try to take a pic and someone can surely help you fix it.

Welcome to this forum! I've renamed your thread, and moved it into the Ranger section. Replace that radiator before the antifreeze does damage to the transmission.

To try to clarify what is happening:

The stock transmission cooler and the radiator are built into a single unit. If you stand in front of the truck with the hood up, look at the right side of the radiator. You should see a metal line at the top right corner of the radiator, on the same side as the engine. That is the transmission cooler line, there is one at the top (the inlet) and another at the bottom (the outlet).

What is happening in your truck is that there is a leak between the radiator (engine coolant) and the transmission cooler (ATF) which is allowing the two fluids to mix. That is bad. The only way to fix it is to replace the radiator with a new unit.

You will also need to flush your cooling system and change the fluid in your transmission.
