18 speed back box disassembled. Grinding low to high. See and understand why🧐

Watch me disassemble a customers Eaton fuller rtlo18918 back box. This customer was complaining of hearing a grinding sound once he flipped from low to high. In the video you can see what it takes to disassemble the auxiliary section of the transmission. I don’t know if you can tell in the video but this auxiliary section was extremely hot. This is only a tear down video leave me a comment I’f you would like to see how an 18 speed back box is built
