sorry if this is a dumb question but what is lugging? i've read it in a couple threads but can't seem to get what it is, any info would be great

 

Lugging the engine is when you are in a higher gear and you can not gain speed, hence the low RPM or lugging. So if you are going 50 MPH up a steep grade running 1400-1600 RPM and can't gain speed no matter how much fuel you give it you are lugging the engine. To correct the issue you must downshift to a lower gear.

 

It's easy to do in these new 6 speed auto trucks too. RPMs are so low with this trans when you are in 6th gear that I often shift back into 5th to stop lugging it.

 

thanks for the info
