Good day. A year ago, I bought an Altima with 3>4 shifting issue. Recently, I had to change the battery and a week later, it got problems shifting 1>2, rising the RPMs and returning instantly to 1 from 2. Scan guy said it was the TCC (solenoid) and turbine sensor. Changed full valve body with solenoids, sensor, oil and cleaning the filter, the issue get no correction. Old owner said one of the electric modules (the one of the speed sensors next to the alternator) had a problem and he replaced it. Need help, please. I have the AT original manual and it only says "TCC solenoid, TCC valve or Turbine sensor"
