Transmission Coolers

[cghbuilder86]

My truck is an '04 silverado 5.3 Z71. How do I know if it has a factory installed transmission cooler? It has what looks like a very small radiator mounted in front of the main radiator. Is this it? I don't guess I have any way of knowing my trans temp. either. Should be okay though because I don't tow near it's limits.

ah, okay good. The first time I heard of one I thought it would be something that had to be added extra. But I was hearing so much about them on here I wondered if it was standard.
