Normal?

[DKVL]

When my 02 Mustang GT hits about 2000rpm I can hear a secondary hum in addition to the normal revving sound. I observe this more so in 1st, 2nd and 3rd gears. Is this normal?

The sound sounds like some restriction of some sort, but I am not sure.


Is this normal?

If you have FlowMasters its normal, thats the drone from hell.

Where is the hum comming from? Do you have stock gears? I assume its a 5 speed, correct?

That description is far to vague to figure anything out... one of those things we'd have to hear in person to say 'ohh, its XXX'.

To throw out another option, it could be an idler pulley.

Need a lot more info here to help.

Thank you to all who has replied.

I do not have a flowmaster, but i do have magnaflow.

I have stock gears and it is 5 speed manual. Should i do a transmission flush soon (never been done before). The GT is at 29000 miles currently. The sound seems to come from where the stick is.

The hum occurs at 2000rpm and up, but eventually it becomes inaudible because of the magnaflow. took it to the mechanic but he said it was normal. Not sure and so i figure i ask mustang experts on here.
