2017 TOYOTA TUNDRA Power Train Problems

The transmission solenoid D shows high voltage which sets my check engine light off. At first no difference would be noticed and it would randomly turn off and then back on randomly. After doing this on and off for the last few months, the transmission has randomly been getting stuck in 4th gear but will lower when slowing down. According to those who have had the same issue have found it to be fixed by replacing the S4 solenoid which seems to be producing way more voltage than it’s supposed to

Diagnostic report indicates problem with shift solenoid and it’s replaceable. Dealership instead charge me for full transmission replacement.

THIS HAPPENED 4 TIMES TODAY THE VEHICLE WOULD STAY AT 1000 RPM WHILE DRIVING WITH NO ACCELERATION POSSIBLE, IT WAS AS IF THE GAS PEDAL WAS DISCONNECTED, TRIED TO CROSS BUSY INTERSECTION , BUT COULD ONLY COAST THREW. ALSO NO WARNING CODES AVAILABLE. LATER THE VEHICLE WOULD NOT SHIFT OR ACCELERATE IT WAS GOING 40 MPH AT 2000 RPM . THE TRUCK HAS 34500 MILES ON IT. TOYOTA SAYS NO ISSUES OF THIS KIND REPORTED AND I'M ONE MONTH OUT OF WARRANTY. I FEEL THIS IS VERY DANGEROUS, TRYING TO CROSS BUSY INTERSECTION , WHEN YOU CAN NOT ACCELERATE I'M GONNA GET KILLED.
