U049FInvalid Data Received From Transmission Range Control Module

This code means the transmission control module (TCM) or another onboard computer received data from the transmission range control module that it judged invalid or out of range. The range control module reports which gear range the transmission is actually in, and when that message is missing, corrupted, or contradictory, the receiving module stores U049F.
