2.9 No Power

[DerangedRanger33]

My truck has no power at all. its a 5 speed and when im in high rpms it makes a grindind noise that sounds terrible. it dosent do it when the clutch is pushed in and i rev it up to 4 or 5 k rpms. only when im in gear driving. its very slow up any and every hill and the fastest i can go on flats is 40 or 45.
any one have this problem? or hear of it before? any help would be greatly appriciated.
thanks

First thing to do is pull codes, see if it will tell you whats going on:

Then check all the Basics: Fuel Filter, Fuel Pressure, Spark Plugs, Wires, Air Filter, Compression etc.

Make sure it is all in working order, may need a tuneup

Is it smoking at all?

Did this just happen or has it been steadily getting worse?

The grinding could be a bearing in the transmission.

I just did a complete tune up on it. new plugs and wires. oil change. air filter. It seems to be getting plenty of fuel because it revs up fine in neutral

anyone at all have this problem before?

ya mine does it 2, my trans. grinds in 4 because the syncros went out of it and mine doesn't have power going up hill ether, i did a full tune up and replaced the fuel pump, and changed the filter and nothing made it better and mine revs up fine in neutral, i think its just an underpowered engine pushin 30's

oh ok thank you very much.

so do you think a rebuilt tranny would help at all?
or should i give up all hope with the 2.9?
Mine was super slow with my 33 12.50s!
its a little quicker now with my 31 10.50s
but still cant get out of its own way.
and cant top more than 50 mph on flat ground

and it also dosent make the grinding nose when its cold

i dont have that problem and im running 31's like black said i would try pulling the codes it might be somthing more complicated than just the simple tune up stuf
