anyone know anything about this code it has something to do with shift solenoid b performance i guessing something with the transmission. what would cause this code it came on after i got on it pulling into traffic with my power pup on performance

 

Very common problem. I would suggest replacing the governor pressure transducer and soenoid. Here's some more info


Symptom:
P1756-GOV PRESS NOT EQUAL TO TARGET @ 35 - 40 PSI (DIESEL)
