Dodge v10 transmission question
So I bought a 99 2500 v10 automatic 4x4 a few months ago. I owned a 2000 v10 3500 automatic 2wd about 10 years ago (and I kicked my self in the butt ever since for selling it). I noticed with this 99 it doesn’t seem to have the pulling power that the 2000 had. With the 2000 I could pull my kubbota 80mph all day long no problem. The 99 won’t do it. The one big thing I noticed is that the 99 seems like it’s a 5 speed auto. I know it’s suppsoed to be the 47re 4 speed but it’s not acting like it. Is there something I am missing here because I do not recall the 2000 being this way nor have I ever seen a 2nd gen act like that.

Its a four speed auto, with a locking torque converter, so the shift you feel right before O/D kicks in, is the torque converter locking.
What gears do you have, and what tire size are you running? I have 4.56 gears in mine, with 33" tires, and while it does not accelerate out of the hole quickly, I don't even need the right tires to push the house off the foundation....... I really want to go to 35" tires..... cheaper and easier than changing the gears.

According to the build sheets both trucks came with 3.55s. I can’t remember what size the tires are. They are either 275 or 285. I have considered changing gear ratios but I don’t know what that will do to fuel mileage. I’m already averaging about 9mpg empty. In most cases going with a lower ratio gives you worse fuel mileage. I have seen it happen once before in a 70 Chevy 3/4 ton where we dropped it to 3.73 and the mileage and power actually improved. I think that more had to do with the weight of the truck and the factory gears being to small which caused to much strain on the motor to keep that tank going.

I think 285's are too much for 3.55 gears, even with a V-10...... bumping to 4.10 should put you right in the sweet spot... Your truck probably came stock with 265's.....
With the mileage on your truck, have you replaced the O2 sensors yet?

No I have not replaced the o2 sensors yet. The truck I am referring to only has 107k on it. I think it does call for 265s but they look like crap on these trucks. The tires I am looking at putting on later this year are going to be slightly bigger than the ones I have now.

Those sensors are still 19 years old, and live in the exhaust stream. 
Not an environment conducive to their longevity. They get old and slow, and inaccurate, decreasing your power and fuel economy.
