trans fluid cooler & air tank

[pumaj24]

I have the stock transmission and trans pan, I wanted to get a trans fluid cooler but I see that they come in different measurements, should I get it measured before I order one of does anyone kno that measurements for the stock?
Is the stock air tank the 2gallon tank?
