    81k is not too many miles to have the transmission flushed, if it was say 150, I would hold off, because by then there is usually too much wear on the valve body by the dirty fluid and a flush, in some cases, can hurt the transmission. As for the tires, it is most likely a bad tire pressure monitoring valve in one of the tires that keeps setting the TPMS light. A good scan tool ( not a parts store type ) will be able to sort out which valve it is.
