I have a 2001 Dodge Dakota PU w/ 188K mi 3.9 V-6 auto. Should I use O/D when pulling a heavy load?
I've received conflicting info on this. My understanding of O/D is to save fuel on the highway, like a 4th gear. I recently hauled a camper trailer over 500 miles in O/D w/ a lot of downshifting occurring. The trip ended OK but I'm still confused. Please help as I love my truck- it has served me well!

Never use OD when hauling or towing any load with your truck, because the end result will be burning up the high gears or trans pump. Which means a trans replacement. OD is for highway and street use for getting decent fuel mileage when not towing. Using OD should be used correctly and going online to find out how should be your move.

If a lot of downshifting is happening, take he truck out of OD and leave it out. Keep your highway speed down enough to make the pulling easy, too.
What you did is hard on both transmission and engine.

No, don't use overdrive when hauling a heavy load or when driving in hilly terrain.
Overdrive is meant to be used as an additional high gear to improve gas mileage while on the freeway in fairly level terrain.
