weird sound [sometimes]
weird sound [sometimes]
sometimes when i start my car shift from Park to Reverse (i drive auto)... my G makes a really loud CLUNK sound. It only happens when i go from Park to Reverse. Reverse to N to Drive and back up makes no sound (including Revers to park) only when P->R... it concerns me cause its quite loud and it only happens sometimes O.o
diagnosis, please?
thanks!

Next time put it in park with your foot holding onto the brake and apply your parking brakes. DON't let your car roll so it doesn't lock up your transmission. Hope this helps.
i did read his thread and thought that we had different problems so i started my own thread.
thanks alot weiboy, ill remember that next time.

so you thought even though you are having the exact same problems, you would start your own thread detailing the exact same thing and just hope it wasnt???
Sounds like early stages of denial....first step to recovery is admitting to yourself that there is something wrong...second....realizing that many more things will go wrong as an infiniti owner.

Op, you should try that out ASAP. IS the clunk noise coming from your transmission area or the shifter
Background: I drove my car pretty hard and didn't touch it for a week and left it in my garage when the temps at night averaged 36F-37F.
When I started up the G tonight, everything seemed normal at first. When I shifted to reverse in order to back out of my garage, the car wouldn't budge. Parking brake was off so that wasn't it. I shifted back to neutral then back into reverse; held the clutch fully down for a full sec afterward. I then tried to slowly release the clutch out to see if I can get it to roll. It started moving out then I hear a loud CLUNK as I backed out and the car shudders a little. I turn off the car to check to see if I ran over anything but nothing was there. I started driving up the block and I smell something weird but it goes away in about 5 seconds.
After driving for a bit more, I pull over and decide to turn off the car and restart it to see if it would do it again. The car made another clunking sound but not as loud as before. I drive around a little bit more and the clutch felt a bit off but gradually started feeling better. I head home, turn it off, turn it on again, started smooth with no clunking sound this time.
Does it sound like I glazed the clutch pretty bad or is it from clutch sticking in the cold temps?

2. i drive auto, he drives manual. different transmission.
3. my car neither had an issue moving nor did i smell anything. i was just concerned about the noise which was the only thing we have in common (which is probably different noises at that).
i didnt make a mistake, thus i dont have anything wrong to admit to.
ill keep your tip in mind (i use the parking break frequently) since the noise comes around randomly. as time passes and i dont hear any other noises, then its probably what youre talking about haha.
thanks!

its actually coming from the transmission area.

i can be pretty positive that might be your issue and it's not any issue at all. i have known lot's of people who parks their AT's on uphill's downhill's and never use their parking brakes lol. after i tutor them how to correctly park their cars they never had that problem afterwards anyway. after you put it on park without using the parking brake your car will roll a little bit till your tranny locks and that's when you'll get the clunk from your transmission when you try to get it out of (P) to (R). hope this helps!

^^^ +10000 exactly what he said. since the tranny locks up it clicks really hard to get out of the park gear. almost feels like something broke lol. You will notice this occurs only on an incline. I always use my e-brake and when I dont push it well this happens. Also I always prefer to come to a stop, put it in nuetral, then push the ebrake down, leg go of the brake pedal and then put in park. I guaranty you this will solve the issue. And you are right this is a separate issue from a manual transmission. I have both a manual g37 coupe and a auto g35 sedan thats how I know this lol. Good luck
this is not a problem
in a normal differential, there is about a half inch of "backlash" in the rear differential before the pinion gear hits the ring gear.
you can test this your self by putting the car in neutral and spinning the drive shaft by hand (it will spin freely until you hear a "clunk" which is the sound of the pinion gear teeth engaging the ring teeth). or...you could just read the fsm
in automatic cars, that "slack" is taken up when you put it in drive, and hold the brake down. if you keep that brake down and turn off the car (i.e., leave the handbrake up) you never release that "slack", hence why the sound goes away if you do this
in manual cars, that "slack" is never really taken up, so you always hear that sound when moving from a stop (releasing the clutch) or acceleration after coasting
for some reason, this sound is much more mute and less apparent in FWD cars. new owners of rwd cars and full time awd cars complain about this often

read this:
It only happens when i go from Park to Reverse. Reverse to N to Drive and back up makes no sound (including Revers to park) only when P->R
but still, even with his initial complaint, what I mentioned is one of the things to rule out on your way to diagnosis of his issue (i.e. shifting into reverse can produce a distinctive sound b/c you are reversing the direction of the drive shaft). Hopefully its just what I mentioned and nothing serious.
oh, well my post was more in regards to the other comments about "clunk" noises.
