2006 Dakota 3.7L V6 powertrain noise

My 6-speed manual trans. Dakota makes a chattering- noise when the motor is lugging. The dealer confirmed the noise is there but does not know what is causing it. A similar truck on the dealer's lot has the same noise, only louder, and therefore they conclude the noise is normal. A Chrysler rep. told the dealer they are not aware of a problem. Everyone who rides in my truck asks me what is wrong with the motor.

I would like to hear from other 3.7 V6 owners who have (or do not have) noise like this. You can reach me off-list at jackf at earthlink dot com, if you wish. Thanks for your help.

Ever consider not lugging the engine? I don't believe they were designed to be run that way. My 1500 will "rumble" some if I lug it down, (5 spd manual), so I try not to do that. The power band is somewhat high in my

4.7, and probably in your 3.7 also. HD

Yep...I learned to drive a stick in 1969 and was taught that lugging an engine is very bad.

What means "LUGGING" an engine? Is something like use the engine to stop the truck, with a lower gear?

Lugging the engine is when you are in a gear that is too high for your speed, (engine rpm is too low). Trying to accelerate up a hill in 5th gear with the engine at 700 rpm would be an example of lugging the engine.
