New transmission oil cooler
I just want to share this experience...
I don't know why H2's has that small tranny oil cooler. My Yukon GT has a similar transmission (4L60E) and came with a bigger/thicker one from factory. I read about some heating issues on H2 trannys. Mine some times reach 200F or a little over. Yesterday I install a new oil cooler Tru-Cool (40,000GVW) and incredibly the temp low to 150F. Hope this help to extend the life of the 4L65E.
