How to replace the Transmission Oil Cooler in a 4L80-E automatic transmission on 2001 Chevrolet Suburban 1500?

The first step to replace an auxiliary coolant in a 4l80-e transmission system involves unscrewing the two bracket bolts which maintain the Transmission Oil Cooler against the radiator support before removing the cooler itself from the bracket. Installation requires two supportive bolts to secure the Transmission Oil Cooler against the radiator support at 12 nm torque (9 ft. Lbs.) while positioning the guide pin bolt into the support opening.
