HELP ! P0778 2012 Nissan Altima
Hello I have a 2012 Nissan Altima with 140k miles on it giving me a P0778 code and the shifting is being kind of wonky, the code says it means " Electrical." It indicates that the vehicle's Transmission Control Module (TCM) or Powertrain Control Module (PCM) has detected an electrical malfunction—such as a short circuit, open circuit, or abnormal voltage reading—in the circuit that controls the transmission's "B" pressure solenoid. " I've had the car since 60k miles and have taken fairly good care of it and it's been good to me. I changed my tranny fluid last week but the code came right back. Tomorrow I'm gonna do my trans fluid again and replace the transmission pan filter and the CVT filter in the engine bay, and test the solenoids with a multimeter. If anyone can make any other suggestions or if you've dealt with this code before please any help is appreciated, thank you !
