The curves are numbered, and at the number 6 curve it is not very steep and I can upshift to 3rd and drive about 400 yards or so before I have to drop to second. It doesn't lug at all, picks up speed normally. When I get to the 9 curve, the grade raises and there's no way it would pull in 3rd so I have to drop there. When I go all the way up in 2nd, it's the same curve, #9, where it begins acting up too, where the grade begins to become the steepest.

I'll mention it to him tomorrow. Any idea as to why it would do that in 2nd gear and not 3rd?

Hey guys, I am hoping someone can help me out here. I'm a slate hauler at a coal tipple and I've been having some problems out of the RD800 I drive. My boss/mechanic hasn't been able to figure it out yet and I'm hoping someone here could maybe lead us in the right direction. Basically, the truck just loses power sometimes in 2nd gear when loaded going up the haul road/hill. Some of the grades are too steep to pull the load in 3rd gear, so I pull it in 2nd and when I come to the steeper parts of the hill it begins to lose power and falls on it's face if I don't drop to 1st and even then it still acts like it don't wanna pull it. However, if I drive up the hill in 2nd gear and when I come to a place on the haul road where it's not so steep, if I upshift to 3rd and then run it up until the next steep part and then drop to 2nd it will run fine the rest of the way and does not lose power. This is crazy to me and doesn't make any sense at all. Also, it is real hard to start in the mornings after it has sat for a while. I have to crank the heck out of it for minutes before it finally sputters and idles normally. We've changed air filters, fuel filters, turbo hoses/intake and it's still acting up. I'm not a mechanic at all, I only know how to grease it and throw on fan belts but I'll try to answer any questions you might have for me. Would this be a computer issue, a mechanical issue or maybe some kind of fuel issue? EDIT: Oh, and it does not show a computer error code when it does this. The light doesn't even come on.
