Reprogram 8hp45 or 8hp70 TCU?

[chuck01835]

Can any chrysler techs out their tell me if a new or remanufactured valve body's tcu will come with the firmware installed, or will it be necessary to flash it before installation. I understand that it will have to be reset and that there's a procedure to reset and learn the adaptive settings, just didn't want to get it installed and then find out i can't drive the truck off the lift because the TCU's program isn't loaded.


Thanks Chuck
