Whats up G member. I got 04 auto g35 coupe.
I'm sometime doing drift w/ my g with manual mode.
I did drift without heating my engine sometime... and few days ago, I did real HARD acceleration with 1st gear and tried to turn it into 2nd gear. manual shift
doesn't shift to 1st to 2nd gear even if i change it to D mode.
I turned off ignition, and turned on my car. Auto mode and Manual mode worked without any problem. I changed my trans oil 2 months ago. and 110000 miles on my car rite now.
I brought it to my mechanic friend, and he checked trans problems with his device.
He said that trans swich up and down problem was detected.

What kind of problem is that??;;
Is that just swich problem or TRANS problem?

Please help me.! it happened again today when i did drift.

 

Well, welcome to the forum...

You for one should never drive the car hard until it gets up to operating temperature and two I question the trans oil change... was it a flush or just a pan drain and fill?

 

Pan drain and fill.

 

Odd, well search your code maybe you'll find your answer.
