Curious about rpm
#11
That does sound quite high. At 110 km/h I'm at about 1750 Rpm with 3.55 and 285/75/16's. Rpm's are lower because of my larger tire size, but still, you should be getting better than that by a long shot. Either your OD isnt engaging or maybe your tach is off like SilverSS suggested.
Are you pulling anything or carrying a lot of weight in the truck?

Without anything needing to be done on my Ram today other than vacuum carpet from dirt and little pieces of plastic after replacing dash, and checking the oil, I tend to over think things.
Two weeks ago, took the Ram on a 1000 mile trip to Houston and back. Got about 11mpg. Truck ran good, but darn, can't afford that! Yota gets 17! I noticed that at 70 mph in OD, rpm is about 3200. Is this normal? Seems pretty high to me.

No codes. In fact, while driving, I had MTG 2500 connected and glanced at it occasionally. Showed to be in OD, TC locked up.....
And 8uzzsaw, minimal load - three adults and luggage for one night. Nothing in bed.
Got pretty good at dropping tranny in just under 2 hours, but don't know what to look for. More research I suppose. 3200 rpm would explain gas mileage if it should be about 1000 rpm less at 70 mph.

I wonder if the wrong TC could cause this to happen? The box had the right part number on it, but TCs are seldom marked with part number....either that or I may have to drop it and pull OD off and check it out.
Guess this should be in tech section instead of general discussion. I was hoping that 3200 was normal .....

Doesn't matter what the scanner says. You need to push the OD button, if OD is working, it should drop out of OD and RPMs should go higher. If there is no change when you push the OD button, it's not going into OD.
