hey guys my friend owns a 03 g35 sedan and his tranny is stuck on 3rd gear
he starts the car, puts it on d and it automatically goes to 3rd without even pressing the pedal, it stays on one gear it won't go up nor down. Wat do u guys think that could cause this problem?

 

the transmission.

 

that would be 100% trans fail safe, get the codes and see what the issue is most likely the trans is junked and it needs a reman or new unit. i know its ****ty news.

 

sorry man.. warranty?
