Have an 02 2500HD, LB7 and an Alison. Trans as rebuilt several years back by a friend, all the available updates were done to it. Has had regular fluid changes. Have an Edge CTS2, think that is the model number on the windshield and has tunes from a shop in Idaho, using EFI Live. Fluid temp was way higher then normal. Hit the sump with an infrared thermometer, gauge said 235* sump said 150*. Replaced the pressure switch. Started the truck, codes were present. Checked the connector at the back of trans, was wet with ATF. Replaced the internal harness. Also replaced the NSBU. Fired truck up, codes still there. Checked all the grounds, they are all good. Any suggestions?
