Interesting that it doesn't seem fully related to the TCM or gear box anyway, possibly a dicky sensor connection maybe.....414 mentions ACC, Adaptive Cruise Control so thats a pointer.......... "U" codes are network so, I would sit and wait if it all runs okay and the dash doesn't light up then its happy, the codes may be just initially thrown and will take time for the system reset...
