My 03 does it. I think the noise comes from the tranny. Such a lovely sound to hear when you are driving.

so all rangers you cant run them at less that 2000 rpms....it is like a vibrating rattle noise.....it stops *** soon as u get above 2000.....i usually shift at like 3000 so do i have to keep it in that little range.....every other car iv ever driven can cruise at 1500 with out a problem.....is bad for the tranny to do it? cause i usually drive in 4th going 35-40 and at like 1800-2200 rpm's and it is constantly making the noise...i just turn the music up....should i stop doing that? thanks

when you are driving with the engine a too low of an rpm, wayy below the power range

you cant do it with an auto greg, it will downshift for you.

as for the OP it shouldnt do it at that high of an rpm, check your exhaust heatshields and tapon your converters with a rubber hammer and see if they rattle, tap them on the seam

I think what you are hearing is gear rattle...each firing of a cylinder accelerates the flywheel to some degree. Think of the steady state rpm as a carrier, with these pulses superimposed on it. Even though all gears are meshed, for each gear, torque only flows through part of the transmission. The noise you are hearing is the rattling of the gears not carrying torque - they are rotating back and forth against their neighbors, excited by the firing pulses of the engine. The actual noise is when the unloaded gears go into resonance. When the engine rpm picks up, the gears move out of their resonance rpm, and the noise goes away.

This won't hurt your transmission - it's a noise problem; the rattling gears aren't transmitting torque. When transmission cases were made of cast iron, this problem wasn't as great - cast iron dampens better than aluminum.

If you want to hear really loud gear rattle, try lugging an F350 diesel that doesn't have a dual mass flywheel - whew!

One way OEM's could reduce the rattle would be thicker tranny fluid, but you get greater losses, fuel economy goes down, extreme cold weather performance suffers until the transmission is warmed up, etc. There are other methods as well, but they are expensive, and have their own problems.

ya it is definatly not my exhaust rattling....i can hear it right under the center console and by the tranny...it almost seems like it has gotten worse than when i first got it. i put some dynamat around where the shifter comes in the floor....do u think changing the fluid would help...im sure it hassent been changed in like 20k miles. also it doesnt seem to do it in 1st gear only the others...i just know it is an annoying sound. thanks

ok well i changed my tranny fluid and used Valvoline max life dex/merc. when i pulled the drane plug the whole magnet was covered with metal shaving about the thickness of a dime....it looked like anti-seize, thats how fine it was and it way gray like that....and then there was a some chunks like the size of grains of sand. how bad is that? also it still makes the noise. is there any thing i can do about it? thanks

Sounds like normal tranny wear. You can get rid of the noise by buying an auto.

Has the noise gotten worse with time? If it has, it may be the main friction damper washer in the clutch disc that is wearing. I'm not suggesting you change the clutch. The issue is inherent in the transmission, and is aggravated by the firing pulses of the engine. If your engine is running rough, that will make things worse. The noise will be louder when the engine is more heavily loaded - the heavier your payload and the harder you press the throttle at those low rpms. As the transmission loosens up, it's internal friction reduces, and provides less damping. That's also why it gets worse as the transmission warms up - the transmission fluid loses some viscosity.

I don't think there is much you can do, except trying to avoid those conditions that make things worse. I'm attaching (trying to) a drawing of a clutch disc that lists all its parts - there is other info on it that may give you a better picture of what is going on. It's from the Luk website (I have no affiliation with Luk, I'm just familiar with the company). They are a leading producer of clutches. There is other good info there as well. Other websites you might check out are Valeo, Daiken, and Sachs.


Sorry I can't offer a fix. Did the drawing come across the web?

metal will show up in any manual tranny fluid, its the nature of making gears come together, but if your getting large shavings or excessive amounts it can be caused by the gears grinding in bad shifts happen and added up over time. i wouldnt cruise any motor but a v8 at 1500 rpm's though.

backlash, never found a manual that doesnt do it.

Its just the Ranger Growl - Certain years have it bad, especially in the 01-03 range, Replacing and rebuilding the entire tranny wont fix anything - It does it because its just the transmission in our trucks letting us know why not to drop into the 2000 power range.. keep it at 2200+ and youll be good; I usually shift at 3300-3600 on average anyway, and it keeps me down to about 2500 on the lowside of an after-shift.


Nothing to worry about! Its perfectly normal!
