I have a 2007 Avalanche LTZ 4x4, 5.3, 3.73 rear end. I don't believe this comes standard with the transmission oil cooler that comes with the 6.0, 4.10.
I spoke to the dealer about installing the GM cooler because I will be towing a 4000 lb travel trailer. Anyway, when I look through the grill at the radiator, attached to the left side is a small finned 3" by 12" object mounted vertically. It has a line running into it through the fins and back out. Both lines run back under the engine towards the transmission. Is this a small transmission oil cooler? My trans temp usually runs from 150 to 165 in normal driving.
