How to replace the Transmission Oil Cooler on the 4L80-E automatic transmission on 2001 GMC Savana 2500?

The 4l80-e automatic transmission requires removal of the grille assembly before Transmission Oil Cooler replacement. You need to remove four bolts securing the auxiliary Oil Cooler to the radiator support on vehicles using an engine that is not the 4.3l. Both 4.3l engine and non-4.3l engine vehicles require removal of bolts attaching the auxiliary Oil Cooler to the radiator support. The installation process requires tightening the four bolts that hold the Oil Cooler to the radiator support at 10 nm (89 inch lbs.) for all engine types. Finally, reinstall the grille assembly.
