It may sound dumb, but have you ever changed your fuel filters during the time frame you have had this problem?

Have you done a stall test on the transmission?
How many revs does it give you?
No I have not, how do you go about doing this--leave the air brake on and block the tires? Can I do this on the flat surface inside my pole building? How do you analize the results?

I think we might be getting to the problem.
The cold transmission doesn't help matters at all. I've stayed in a nice little campsite in Klickitat Canyon near Glenwood WA a few times. It's a fish camp, better suited for campers on trucks. I have about 4" clearance on each side (trees) to get in there. :B It's the kind of place where a 40' coach just doesn't look like it belongs. ๐
The place is on the river, and there's a climb of about 6% either direction when heading out, and it's in the middle of a curve too. (The entrance is pretty much the bottom of a V notch) It's also a busy road for log trucks, and many's the cold morning when I'm patting the dashboard saying "COME ON, BABY, COME ON BABY, PLEASE, LET'S GO!!" as I'm looking in the mirror for the grill of a Peterbilt pulling 80,000 lbs. of logs that could be rounding the corner any second. When she's fully warm, she rockets away from the same kind of place. (Relatively speaking)
The manifold leak is a BIG issue, even if a small one. A turbocharger is a centrifugal compressor driven by a turbine. (compressor and turbine are directly coupled together) You'd be surprised at how a tiny leak can really effect the turbine's speed, and if there's no boost, it ain't makin' enough torque.
A stuck shut flapper (exhaust brake) will usually kill the engine, and it won't rev unloaded, so I doubt that's it. If it's all the way shut, it shouldn't even idle. But, an exhaust manifold leak will keep it from making boost until the RPM comes up. And, as mentioned, a cold transmission will keep the RPM from coming up enough in the first place, and when everything's warm on the road, the higher from-dead-stop RPM can compensate for the low boost and/or turbine speed.

Dave, as you stated, you do not have an electronic engine... something pulls on the black lever in the picture I posted above. There is no derating on your engine. How many RPMs do you get and how much boost pressure when you try and go up the hill? If you are getting 1500+ RPMs and 10 psi boost then I'd say your tranny is low on oil and it is slipping. Econo mode raises the shift points, not lowers... but in first gear it makes no difference.

check the oil in the tranny when was the last time it was changed
