My car drives great but there is a slight rattle like something is bouncing when I am in a low rpm or in a braked position but still in gear, you can actually feel it on when placing hand on manifold. When my car is idling while in park or neutral the sound doesn't occur. I've had other friends with g37s give me suggestions as if it's bearing rod or hydraulic pump. It's almost sounds like something is loose. Doesn't sound like most videos I've been seeing on YouTube. *clink*clink*---*clink*---*clink**clink*. I had a bit too much engine oil in it. About half a finger nail but I don't feel that would be the cause.. Again my car drives fine when on the road and moving. If anyone has had the same problem and has a solution. The help would be greatly appreciated.

I will post a video today showing the noise.

 

Bad cat. Loose shield. Kinda hard to keyboard diagnose. Take to mechanic or actually get under your car. We can only do so much but you must do the leg work.

 

I had removed the transmission and torque converter myself and had it checked professionally because I thought that was the problem as my car stalled twice in a row one day. I received my transmission back and was told is was in perfect condition. As I installed everything back together. It ran great and I had it smogged the next day. Then the noise occurred 3 days after.
I will go under again ASAP and record the noise to give you guys a better idea.

 

Unreal. You removed the trans to have it inspected to find out it' fine. Why not take to mechanic to have it checked first?

 

I did take it to a multiple mechanics to have inspections and they all didn't want touch my car because they said everything was fine with it but as an owner and driver of my car I knew they were wrong. I took it to the dealership were I had originally bought my car but since my car 77, 000+ miles the warranty voided. They said they would charge me 750 to take a look but if no one else can find the problem I feel like they want to rip me off because the guy didn't seem too enthusiastic about it.

 

Sorry bud. Mechanics said trans and torque converter were fine after you removed yourself. You chasing a ghost. Sounds don' always mean somethings broken. Car shifts fine drives fine no codes. Drive it enjoy it fix it when it actually breaks.

 

I made an appointment with the dealership to get a what seems like a 7th opinion.

 

I may be overthinking it but I'm just used to my car sounding smooth and not like a loose bolt jumping around. Drive throughs and stop lights are annoying because of the loud sound. I guess some loud music and bass will fix it for now😎

 

Help us understand why you pulled the trans when it shifted fine and mechanics said it' no issue?

 

how do u guys with tan interiors stomach it?

 

Before the fact that I pulled it down. My car stalled twice back to back and would not move unless I pressed the gas a bit then put it into drive. My assumption was that the torque convertor was the problem like if it wasn't making my car move...if the car is in PARK no noise is being made so I'm pretty sure the engine is completely fine because everything is moving in it... Now if my car if shifting fine then transmission is fine... Something in between is the problem. Pulling the transmission is no problem as I'm a techy kind of guy and if I can do it without spending a ton I will. I also have the help if my father with 35 years experience in mechanics. Pulling transmissions down isn't a problem.. If you were hear in person you would really think it the torque is the problem judging by the sound. I pulled it down and had the torque converter checked with the tranny and I was told everything was fine but the torque converter had some overheating burns on it. I never replaced it just only put it back on. Everything is back to how it was before I pulled the tranny down. So main reason I pulled it down was for the torque converter. Honestly the guy could've lied to me and I just don't know it. At this moment I'm at lost for words.

Im really curious on what it is this "Ghost" I'm chasing but I hope I find it. Sorry waisting your guy's time on this issue. I'll keep you guys updated on what I find out. I have an appointment on Saturday at infiniti.

 

I tried looking for a black interior but this one just caught my eye and with the brown metallic paint I couldn't resist! I just hate the fact it gets dirty so fast😨

 

tan leather interiors always look stink and dirty to me when it gets old. but it probably is stink and dirty tho

 

How can a mechanic say a transmission is fine when it's not even in the car? Transmissions are like a bunch of parts (gears, friction plates, clutches, ect....) stacked in order on top of one another.

 

bro go away. Your irritating and causing a stink to the forums. No one likes you here. Keep you be to yourself broad.
