Piranha Posted April 2, 2015 Share Posted April 2, 2015 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. Quote Link to comment Share on other sites More sharing options...

Piranha Posted April 2, 2015 Author Share Posted April 2, 2015 wheel spin? I thought this could be the case but I asked her if the slip light came on and it didn't. Quote Link to comment Share on other sites More sharing options...

ZMANALEX Posted April 2, 2015 Share Posted April 2, 2015 (edited) What ^^^^^ marzman has said. Then report back. FYI the auto box in the G35 Skyline is the same as the VQ35DE. I have 2 in stock at the moment, however I doubt very much that you have an issue where the box will have to be swopped out. Also the fluid is meant to be fluid for life. Alex.

Piranha Posted April 2, 2015 Author Share Posted April 2, 2015 Thanks marzman & Alex It most definitely hasn't happened to me yet and I've taken it for a spin this afternoon testing both auto & semi auto it pulls nicely with no noise or burning smell. I'm beginning to think her foot slipped between brake pedal and accelorater 🙈 Quote Link to comment Share on other sites More sharing options...
Piranha Posted April 2, 2015 Author Share Posted April 2, 2015 Also the fluid is meant to be fluid for life. Alex. That's good news thought I may have to change it at some point. Quote Link to comment Share on other sites More sharing options...

Fill your boots mate as the fluid is circa £200.00 Wow that much I thought it would about £15 a quart for s matic. I've read so much conflicting information on wether to change the auto fluid or not. I know there's no filter to change and had read that changing the fluid on a 40k plus car could do damage to auto box. Quote Link to comment Share on other sites More sharing options...
longsh07 Posted April 2, 2015 Share Posted April 2, 2015 To be honest I think it will probably be wheel spin. Traction control sometimes doesn't kick in at all if I pull away a bit sharpish in a straight line. 1 Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted April 2, 2015 Share Posted April 2, 2015 (edited) It is J matic that you require not S matic. Edited April 2, 2015 by ZMANALEX 1 Quote Link to comment Share on other sites More sharing options...

You could be right as she can be a bit heavy on the gas lol Quote Link to comment Share on other sites More sharing options...
jimboy2 Posted April 2, 2015 Share Posted April 2, 2015 I think we have all learned a valuable lesson here. Don't let wife/girlfriend drive your car! 1 Quote Link to comment Share on other sites More sharing options...
Piranha Posted April 2, 2015 Author Share Posted April 2, 2015 It is J matic that you require not S matic. Oh I thought J matic had been upgraded to S. Like I say I've read so much info that conflicts. So just to confirm Alex, although it does not require changing, if it ever needed topping up it would be J matic? Thanks Quote Link to comment Share on other sites More sharing options...

I agree it's better to use what you know and trust and if you can still buy it they must still be making it. Quote Link to comment Share on other sites More sharing options...
