Transmission issues?
Hello,
Took my good old 1992 F350 7.5L (love the truck) 2 hours up in the mountains to get a load of wood and camp/fish. Had a great time, but on the way back with about 1/2 chord of wood the truck lost power on the uphill. When idling, the engine sounded just fine. If I stopped for a little while and let the truck cool, it would drive great for a while then act up again.
I did feel a lot of heat from under the gear stick and I noticed if I kept it from revving up the engine when accelerating it seemed to perform better, but still not good.
Has anyone run into something like this?

I drove it again after getting home and letting it cool off. Runs great for a bit, but power does go down after it warms up. Not a transmission issue, I think you are right (not that my opinion holds any weight). I'm thinking fuel delivery or blown head gasket, but I'm just guessing. I hate having my truck have issues, but I do enjoy learning how to work on it (and how everything works). I just wish it happened when I didn't need it for gathering firewood.

No. Your pressure gauge is either broken or not making contact with the schrader valve core.
Is this a manual transmission truck?
Are you saying when you hit the gas, the engine revs up but vehicle speed doesn't increase?

I tried another pressure gauge, but it registered zero also. After turning off the key, I put a screwdriver in the schrader valve and gas squirted out...so it seems the valve does not get opened by the pressure gauge adapter since there is pressure in there and the truck will start & run.
Yes, it is a manual transmission..and no, the engine does not rev up when it starts bogging down. It loses power on uphill and makes a strange noise in the front. Someone suggested it might be the catalytic converter acting up and not letting exhaust out...I don't know what to think at this point.

You definitely need to get a fuel pressure gauge and working. If you have to, try using a valve-core remover tool and completely remove the schrader valve from the fuel rail to get the gauge to work.

Code 41 indicates the engine is lean. I'd verify what you fuel pressure does under load. Try snapping throttle wide open and letting the engine get a good rev in (close to redline), what does the fuel pressure do?

I wanted to report back that I took out the catalytic converter, and it had junk just falling out. We gutted it and put it back to see if that was causing the issue. It ran better than it ever had since I got the truck. Now I need to get a new converter since I know it was the issue. Was able to drive up in the hills and pull some logs out of the woods with it.
I also wanted to say thanks for everyone who contributes to this forum, it allows people like me to fix problems way above my pay grade. If I would have gone on my own, I would have been tinkering with the transmission rather than the real problem.
