2018 Tacoma automatic transmission shudders, hesitates and misses at speeds between 35-60 mph. This happens constantly. Slight pedal and low rpm's in 5th and 6th gear is when it's most noticeable. On occasion, there is a more serious miss, which feels as if you have turned the ignition off at 50mph and then right back on. This does not happen frequently, 4 or 5 times in the 20,000 miles I've driven it. The shudder has been looked at by Toyota on 3 occasions, and has bee shrugged off as a "typical characteristic of the vehicle". Toyota north America made an appointment for me to see the service manager who rode with me and felt the shudder and missing. He had me test drive a 2019 v6 automatic off road and it also had the shudder and missing in the same range. The final outcome was that it is a characteristic of the vehicle and there is nothing that can be done. The fuel pump recall was done. The power train was re-flashed. No change in the condition. It is very unnerving and disappointing that they consider this condition acceptable.
