Took my 1097 off-roading in October 2021 and started having problems with it starting strong and would gradually lose power on the way home (80 mile trip). Checked the speed sensors, not the problem. Drained the 4L80E transmission, replaced both the the 1-2 and 2-3 shift modules, filter and put in new fluid, and had some relief but still having problem. Took it to the shop that does the work on the 1097 I cannot. That shop ruled out both the transmission and the TCM. The shop did come back and say the sensor in the attached pictures was disconnected and corroded and probably the cause of the slow power loss. The shop found the sensor was connected to the main wire harness and located where the transmission and transfer come together. The sensor was not internal but instead tied up with wire ties inside the rubber sleeve also in the attached pictures. Looking for some help in finding out what this is. I am thinking transfer case speed sensor. Neither I nor the shop can find what this sensor is in the TMs and there is nothing looks exactly like it through the normal suppliers like MAC Motors, Midwest Military, Eastern Military Surplus or SECO. Any help would be greatly appreciated.
