Hi everyone,
I currently own a G6eTurbo 2010 model with approximately 100,000 kms. I have done nothing to the car besides a rear muffler delete, besides this it is stock as a rock.
The other week I was driving on an expressway travelling at about 100 kmh and then accelerated, not an overly hard acceleration but was overtaking someone so a reasonable push.
As I put the power in the car lost power and flashed “Transmission fault” on the display. It put me into limp mode (3rd gear). I pulled over turned the car off and turned it back on and it appeared fine let me drive normally.
I took the car into a mechanic and explained my problem but they said they couldn’t find any codes and they test drove the car which appeared fine to them.
Since this I have tested the issue myself and found once the car hits operating temperature if I apply any hard acceleration after about 100 kmh the car immediately faults, limp mode, turn it off back on and it runs fine. I borrowed a reader and found the following code myself:
DTC - P0735 - Transmission gear #5 incorrect ratio. DTC status: Continuous memory DTC.
Has anyone had this issue or know what is going on with my car! I don’t want to keep mechanic shopping and being charged silly amounts to be told its fine. Any help is greatly appreciated.
