hey all

I noticed while driving today when accelerating i hear this humming type of noise coming from the vehicle. It is not an ongoing noise but rather it comes and goes, I notice it more when driving on highway speeds.

As well I am noticing the ride is not as smooth as it was before....there is more jerkyness when trying to accelerate quickly and that instant punch is not there like before in my opinion.

Anyone know what might be the problem? No error messages on the dash. Any help is appreciated

 

You think that's the issue? Is it expensive?

 

so i drove it for little while today and found the following

when i accelerate i sometimes here humming noise that lasts for a few seconds
its also not as smooth when accelerating hard too much jerkyness
when i start car it revs to like 12 on the revs gauge then the engine sound dims down and the gauge goes down to 8 or so

dunno what is the issue

 

Mine was torque converter and coolant in the tranny

 

how much it cost?

 

What year is your car

 

It was under warranty, all I paid was the deductible

 

It is a 2003 but my radiator was updated before i bought the car

is it possible it could be a fuel pump issue and the humming noise is the fuel pump?

 

finally picked up the car, they also replace the radiator as well. i am very happy that i got a warranty. wowzers.

 

do you think changing rear differential fluid would help?

 

Does your car accelerate past 4k rpm when driving?
