I need someone who is very familiar to help me out with the marine gear oil cooler which is in the lower part of my HE. The oil cooler is stamped with an in and an out but the hoses which bolt into the end cap are reversed according to the Allison info diagram I found. This is an Allison M15. I’m just not sure if I can flip over the cooler so that the in and out holes line up with the proper holes in the end cap which leads to the hoses. Any help would be greatly appreciated. I can be reached at 330-233-3782. Thanks Alex Sherard
