Hi all new to HPT. I have a 2006 rt and am having issues with the NAG1 trans. I did a EGS5X initialization as well as resetting the adaptives. Now the transmission shifts very inconsistently from 1-2 and 2-3 then gets stuck in 3rd until I restart the car. Manual mode will not do anything once it gets stuck in 3rd but works fine before it hits third. I get a P0703 "Gear 3 incorrect ratio" code but nothing else relating to the TCM. Has anyone else had this problem? Should also mentioned I have tried 2 different TCM's from various 5.7 2006 chargers and same issue. Any help would be greatly appreciated.
I'm leaning towards it being either the valve body or conductor plate but am skeptical that something just happened to let go at the same time that I did those procedures.
