ok so the car at hand is the 03 g35 sedan it's automatic with septronic so I started noticing when I gas it kinda hard IN AUTOMATIC I can feel a grind and a pull from the car when it switches to 3rd gear can anyone help please

 

It's the pre-actuater located in the left lateral quadrent of the osmosimeister in the tranny. Without your great description I would have never pin pointed it.

Use SEARCH!!!!!!

 

Sorry I'm a noob I wouldn't know what to search or where to search for this problem what should I even do to resolve this problem is it serious?

 

Does this happen when you put it in 3rd in 'manual' mode? Is the noise during the upshift or downshift? Try going through some basic fixes like replacing the transmission fluid, tune-up, timing belt etc. as these are basic maintenance procedures anyway. All else fails, go to the dealer and get a diagnostic and hope you dont get cheated.

 

It does it on the upshift only and it will do it both in auto n manual was mikeyo bein sarcastic with his post?

 

Yes, he's being sarcastic. Try searching the forums about your issue.

 

Yes, they got rid of the osmosimeister after 2003.

 

Replace the tranny fluid, but don't bother with the timing belt, the G35 doesn't have one (it's got a chain). If your car has less than 70K on it, there's a chance it's still under the 6 year, 70K power train warranty. If you've got a carfax report for your car, it will tell you it's in-service date (date it was first titled to a new owner). If it was less than 6 years ago, drive immediately over to a dealer and have them fix it.

 

leave it in auto mode for a few days and see if it stops doing the clunk into 3rd gear, if it does, its just because you suck at using the manual mode.. Mine did that in the Auto mode at first when I got the car, but I think it was because i was really hard on it in the manual mode and the tranny learns from your driving style..it took some getting used to and now is perfectly smooth in Auto, it does clunk sometimes in the EDIT:MANUAL mode..

It seems most clunk going 2nd-> 3rd in the manual mode from what i've read..The auto mode should be smooth tho.

edit: I never have felt a grind though.. so maybe this isnt what your even talking about..

 

Hmm...mind does that. If i use manual mode (the rare times when i do) and shift to 3rd it sometimes shifts in fast and hard.

Never does it in auto though...just manual 2-3 shift.

Is that an issue i need to worry about?

 

Sell it and get a 6MT...


...seriously, I would start with trans fluid replacement, but beware that depending on mileage and how bad the problem is replaceing the fluid might make it worse. This is of course the worst case scenario.

 

I did a search, seems it a common "problem"

It's done it ever since i bought the car at 23K miles. I have 35K now. I never use manual mode anyway, it seems pointless to me. In D it shifts like butter. But i was planning on changing fluid anyway.

 

thx ima go try the tranny fluid thing n then maybe a grounding kit if that dont work i will say this tho after being nice to the car it does get back to normal if i go easy on it while its shifting to 3rd in auto it will go smoothly but then i hit it punched it to the floor and right after that the switch from 2 to 3 was rough again but then again i went easy on it for a few days n it kinda seems to go away lol its wierd but i start talkin to her n i find myself laughin cuz im tryna be nice to her n sweet talk her into not pullin on the switch lol
