Got a shift solenoid B stuck on

What is your question?

Driving down the road today and transmission went out. Pulled over and put in park then tried reverse, d, 1,2,3 nothing. turned off car for about 2 min. started it back up and transmission worked again. went down the road same thing happened. once again turn off turned on and once again it worked fine. I am thinking speed sensor, however when I ran scan tool it gave me a code of P0757 Shift Solenoid B Stuck On. Any ideas?
