Bought another truck couple of days ago ran great and still runs great but throwing codes now and the first time I got the code tow haul was flashing but I didn't put it in tow haul any thoughts? Seems to drive ok now but maybe seems like transmissions a little sluggish at take off maybe. Tha is.

Both are transmission codes, may have been due to a temporary condition.

The tow/haul light will flash on its own to indicate a tranny problem.
When was the last time the tranny was serviced.
