Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question
Do you mean G37 ?
The 2010 G37x Transmissions are great transmissions. They only had 1 issue which is that they are very shifty cause of the 7 speed auto trans. But they had a reprogram for the TCM that fixed that.
Other that that small issue which is resolved by a reprogram, theses transmission hardly ever go
If you have any more questions on this, please feel free to ask.
If not, and you are satisfied with my help please Rate me. I hope that I have provided you with excellent service.
Please be sure to follow your manual as far as fluid change intervals as well, it is an expensive transmission to repair if it gets neglected.
These Transmissions use Synthetic Fluid and do not require as much Maintenance as older transmissions did.
One last thing, if a check engine light comes on that's a warning that something is wrong or going wrong. Do not ignore it, because addressing an issue right away can save you a lot of headaches in the future and money.
Thanks again, Ron
So you know, you G37 also has a 6 year or 70k mile warranty on the engine and Transmission. So it's also good to know you have some protection if there is any issues that will pop up.
