My 2003 V35 / G35 350Gt has done around 43K, I'm not sure if its Auto box is the same as the Z but my question is quite generic.
Last night my wife took the car to work from cold start and once she had reversed off drive, she engaged Drive and as she accelerated the cars revs went up but the car seemed to slip until she backed of the gas and went again.
On questioning her she said it also happened at the first junction she stopped at on her trip to work, then did not happen again.
I personally have never experienced this problem, possibly because I warm the car up before I set off.
For me both the engine and gearbox are nice and smooth.
Has anyone else experienced a similar issue, I have read that auto boxes have a feature called lock up that does not engage until car reaches a certain speed and was wondering if this is a safety feature designed to protect gearbox.
Would this coupled with my wife being heavy on the gas pedal at a time the cars revs are higher due to cold start cause this.
I have checked the fluid at the dip stick and its at the correct level, looks clear on the stick and is the usual pinkish colour. It has a sweet smell and not a smell of burning, so there is no real indication of wear and tear of gearbox, levels are good which indicates no leak and has not been contaminated by coolant.
I welcome your opinions.
