absolutely horrible gearbox and you will need at least a nexiq2 to dianose it,you may actually have to read idividual CAN BUS messages and decode them for failure mode identifier information (FMI'S).
OEM wiring and switches/sensors causes most issues and alot of them were'nt right from the factory.
besides the elec issues air components also cause issues particularly if it's holding in 10th gear.
if it loses communications over CAN BUS it will log rail shift codes cos it torque locks and it cant shift gears. -
