The trans fluid is red in color. Coolant is clear.

Trans fluid leaking in this area pictured would have to come from the front seal of the transmission. If you look on the bottom of the transmission....towards the front of the tranny....you will see two small removable circles.......use a small flat blade screw driver to remove the the two circles. With those circles removed, you will be able to look at the torque converter.......check to see if you notice any wetness. If the front transmission seal is, you will see wetness inside those holes.

The transmission lines pass above the wet area. They are two separate lines. If they develop leaks, the leak will not occur in the area pictured above.

I've seen countless front transmission seal leaks......this does not look like what is happening here. Trans fluid is relatively thick (compared to coolant). It will not travel upwards, nor will it pass to the front side of the torque converter onto the oil pan.

The heater core hoses....the 'quick connect' pieces......they may look fine, but move the hoses a little bit (while the engine is warm and coolant system is pressurized).....move the hoses and see if you notice any coolant escaping past the coupler connections.

Differently coolant from the passenger side





Passenger side all the way to the rear





I think this heater core connector is for the front





This would be fir the rear heate





[I]Both connectors are leaking. This should be why my coolant is leaking leaking puddles. And what hoses to the coolant connector should I change
