Been working on this one for over a week now. Completed a LQ9 with 4L60E swap and a DBC stand alone harness. Everything is reading except for the transmission temp is stuck on 195. Have .8v to Pin 51 on Transmission Temperature Sensor and Pin 40 is grounded. Pulled pins from the transmission and connected to a 2 wire external temp sensor with no change. Truck is stuck in hot mode all the time since sensor is stuck at 195. Have read the forms stating there are 2 different PID's for the trans temp but I am only showing 1. Have a bully dog stand alone monitor that is reading the same as my VCM. I have switched out the PSM in the transmission twice with OEM and aftermarket with no change. Beginning to think it is in my tune but I cannot find where this would be effected. Truck was recently placed on the dyno with no codes. Attaching the current dyno tune for the truck.
