Please Help. 2010 G37 sedan 7AT. Engine seems to start fine. In park and neutral it revs and idles normal. When put into reverse or drive the rpm seem to drop and the car dies. No CELs. Had to start it in neutral rev up and throw in drive to get home. Cleaned MAFs and still does it. Throttle bodies were cleaned 12k ago so I dont think thats the problem. Someone said maybe its a transmission solenoid. Please HELP

 

Hey man, I'm currently in the same situation you were in. What was the cause of the issue and what did you do to repair it? Thanks!

 

Vacuum leak, Did you clean the TB's ? I bet something was left off ?

 

What was the problem?

 

The transmission and torque converter were replaced by warranty. Car was fine afterwards
