How do you know what cooling systems you have all I see is two lines coming from the radiator going to the bottom of the engine block I don’t know if it’s a oil cooler or a trans cooler

If it has a trans cooler? the 2 lines run from the drivers side of the tranny to the passenger side of the radiator.
If it has an engine oil cooler too? there are 2 lines that run from the engine block just above the oil filter to the drivers side of the radiator.
RPO code in the glove box tell the tale too.

So is that a transmission cooler then? Right to
The radiator ?

Yes, those hard lines are for the transmission.
