Hey guys i just purchased a g37
the car gets out of gear when changing from 4th to 5th gear
When i used a scaner it shows that the tcc solinioed reads 0 amps is that normal ?
It only cuts for 1 second and it goes back to normal i ll upload a video later. ..

 

Sounds like you have transmission flare. If you Google - G37 Transmission Flare, you should find something similar to what you are experiencing. Sounds like its something we have to live with.

Some folks mention a grounding kit or transmission flush helping to decrease the frequency of the flare.

 

So it's not a serious problem?
I have a low voltage battery and a spiral cord that's not working (volume control and cruise control isn't working) does that have any relation with the flare ?
