Hey all, I have a terrible leak in my '99 Ranger. Its an automatic with the 4.0. I've gone to Napa and stuck in Trans-X and have had zero luck. I put in an entire bottle of ATF every 2 weeks. everybody was saying to try this https://www.amazon.com/BlueDevil-Rea...=1&*entries*=0 but I do not know what else to try? Any suggestions?

 

Where is the leak coming from? Pan gasket, etc
