Hi Everyone,

I had noticed that my 2010 Infiniti G37X Coupe bucks when shifting at 3,500 RPMS, it does not throw a code. Does anyone have any thoughts of would could cause this?

 

How many miles on the car and have you checked the transmission fluid level? Assuming that you have a 7-speed auto, it could be low on AT fluid or may need a fluid and filter change depending on the mileage. Have you noticed any signs of leaking on the floor/ground where you park it? Start with checking the fluid level and report back with more specific info to get more input and help for your issue.

 

Can you get past 3,500 rpm? If not, then your car is in limp mode.
