OEM AUX Coolers- Location?

[jimlem]

My truck comes with the Z82 trailering package which according to my vin and RPO codes should have an aux engine oil cooler and A/T fluid cooler. I just cannot seem to see them any where. I have no desire to take things apart but would like to store the info for later if anyone can advise the correct location. Thanks.

Do these chassis also have the trans oil coolers integrated into the radiator? Can you trace the lines...??
