I hope this is the right section, it does say drivetrain. I just picked up a cpo'd g35 coupe. When I go to start the car from a cold start when putting my 06/at @ 40k from park to drive or park to reverse the car jerks pretty harshly, at least compared to my previous Honda/Acura's. Just wondering if this was normal. thanks. Ive taken it back to the dealer and they have found no problems.

 

Mine has allways done it and i have a 2003 with 68,000 miles on it and 54,000 miles with forced induction.

 

"When I go to start the car from a cold start when putting my 06/at @ 40k from park to drive or park to reverse the car jerks pretty harshly".

The AT only operates correctly when the ATF is up to operating temperature. This takes 5-10 minutes after COLD cranking. Just as cold engine oil doesn't lubricate well, same with cold ATF.

Failure to properly warm up lubricants is number 1 cause of wear and failures.

 

Are you parking your car on an incline/decline?

 

Thanks for the input so far. The car is parked on a level surface

 

I have the same thing on my 05 G35 Sedan AT

 

I think your just feeling the jerk that pushed downward in the rear. i believe this is normal i think its just the tranny switching to D.

 

dont worry about that start worrying when you dont feel it, is what i was told!!
