Sorry about that was in a rush didnt read what i wrote at all.
First i got a trouble code OF U0101
second i have programmer H&S with delelte dpf
third i change both batteries and top off all fluids looked for leaks.
fourth when thought clean all my grounds so far but two left it got late last night. finish that today.
the truck will run and drive till somethinf does happen causing it to go in limp mode.
the only other thing i have left to solve is i have a little bit of overcharging happen with alternator getting 14.65 .
I know that in Allison transmission programming on the industrial side shutdown go into limp mode if there any overcharging.

My batteries tested good one day and two days later where both die.
still dont have much of a clue because on all the forms that ive read U0101 is such a basic code that cover so much ive have to be very meticulous . im open to any ideas .ive checked the abs wires, the yellowwire like in the lbz, checked all the fuses, test the ignition , grounds, so only got left is the overcharging
