TCM
Good morning,
I have a 2013 f250. 6.7 diesel. Been deleted for over 100,000 miles. Have a new issue I’ve never seen before. Truck tries to start but only jumps. Lights flash, get clicking noises from under the truck. After a few tries, it throws a Po884 code for TCM power input signal intermittent. After the truck is warm, it can crank and start and run fine. All batteries are new. Terminals are clean. Wires are good. Checked the TCM. Opened it and cleaned the terminals with Eletrical cleaner. No bad wiring. BUT, I get no transmissions issues while driving. No slipping gears. The best way I know how to describe the starting process is it’s like the truck is having a seizure. It even resets the sync screen after a few tries. Any clues ?

appreciate the input. I’ve checked all wiring looms. Nothing appears to be broken or damaged. Replaced the relay for the starter already. Seems to be getting worse. Haven’t load tested the batteries yet. I still have power. Both show to have 12v. I’m leaving towards a bad cell in one of the batteries. I’ll update if I can find it. Thank you again.
