    Default Newby needs some help!!

    Hello everyone,

    I have a 2009 Suburban LTZ 4x4 5.3l V8

    I am trying to figure out if I have an auxiliary transmission cooler installed. I have one guy at the dealer saying yes, the other guy saying no. Both over the phone. When I look in through the grill at the radiator I can see an extra mini radiator thing, I am not sure if it is the tranny cooler or if it is a condensor? or something else. I really want to know what it is. Any help please? Does anyone have an exploded view of the engine compartment? Thanks

    For examples:

    Look for trannie coolers en then you wil see axamples for plate cooles at the most and best in placing before your main coolers or AC coolerplate so the cold air hits the externe coolerplate first when you drive.
