help!!new tires and now instant tranny problems

[parttime]

alright guys i went and had a new set of tires put on the truck this morning and desided to go with a 285/75r16 BFG AT.truck was fine before the tires.well the guys put the tires on the truck and backed it out of the bay i got in to leave and dropped it down in drive and it felt like it was in neutral but when i gave it some gas it jumped into gear and then i drove it to another shop where a buddy works and while on the way the tow/haul light started flashing and he checked the codes and it has 2 codes PO730 and
P2702.he said it might need to be reprogrammed for the tire size is this true?

Coincident, IMHO.

I upgraded my tires to that size only in 17" and have not had a problem.
