5at stuck in 4th
I have an 08 g37 coupe with the 5at and literally the second it hit 150k miles it stopped shifting and threw a cel. I used a launch obd2 reader and it doesn't recognize the code being thrown. I changed the transmission fluid a little over 2 weeks ago so I don't think that's an issue. Anyone have any ideas on what it could be?

1) Will it not shift into 5th using DS/Manual Mode?
2) Did you perform the fluid change yourself or through a mechanic/shop?
If possible, you may want to take the car to have AutoZone or someone with a better scanner to check for codes (or, look into OBDFusion or Torque apps).
Right now the issue points to the TCM (Trans Ctrl Module) with AFS being a symptom, not a cause, of a "failure." Knowing what codes are being set will help narrow down what is going on.
