i have a kind of rattling gear noise when i accellerate quickly in first second and third gear. usually happens at low rpms wheni give it a nice push on the gas pedal. could this be from low gear oil because i havent changed the gear oil since about 65-70000 miles, due to me not being able to get the drain plug off.

what could this be from?

 

oh i have 10100 miles on my car now

 

I sure hope that's a typo.

Timing chain tensioner maybe?

 

no its not a typo. do 1999's have problems with the timing chain tensioner?

 

oops, yes it is a typo, its got 101000, damn how did i miss that

 

wow 33 views and only one person suggested something. thats great guys. thanks enervine for being the only one. seriously tho, nobody can give any input on what the noise could be from?

 

any noise in Neutrel ... ? If so .. with or without the clutch in?

My input shaft bearing is worn and I can hear it, need to do a rebuild and I will soon ... just not enough time right now. I notice noise in N, but it's there all the time, just my intake and exahust is too loud to hear it under load. Sounds like rubbing two coins together.

Can you give us more detail ... how loud is it, does it get softer or louder under load, how long been making this noise? ... more detail will net you more responses

 

no noise in N. its loud enough to hear over my jwt intake under load. its a rattling noise that doesnt stop until i let off the gas. its been making the noise for about a month now, i just try to not floor it anymore.

 

hey 99 my 97 maxima does the same exact thing so i dunno if it is normal or not

 

and i dont think its gear oil its something to do with the shift base where it connects to the bar going to the tanny

 

you should fix it and floor it!

 

This is difficult to do an "internet diagnosis".

The rattling could be as simple as something that taps when the car is pushed forward very hard, which would be most likely to happen in 1st or 2nd. Or it could be something within the 1st or 2nd gear teeth pair.

im really worried cuz it sounds more like gears rattling. but i hope its sumthing a little more simple like you said the shifter linkage

 

Gear "rattle" caused from tooth damage usually sounds like a loud RRRRRRRR that is constant and varies exactly in pitch with the speed of the car. Just like reverse gear normally sounds, but louder.

It will change in sound depending on whether you're on the throttle or coasting/engine braking.

yea its not the gears being stipped im pretty sure. the mecanic said it was something to do with the shift link
