power loss on hwy?
I just recently picked up my 01 2WD QC with the 5 spd and 5.2. It has a 3:21 rear end. Gears 1 - 4 seem strong, but when I am in 5th it doesnt seem to have much pick up. Even if I am doing like 70 in 5th and I go into a strong wind or up a hill (or worse both) my truck will start to lose speed even if I have the pedal to the floor. Is that normal? I know the glass pack exhaust isnt helping much which I plan to swap out soon. I did the temp check on the cat and that seems ok although I am going to take it to a dealer just to have them test it. As far as I can tell it doesn't have the death flash either. Like I said 1st through 4th is pretty strong. I can light it up off the line and in 2nd too if the pavement is wet, it's just the overdrive gear that I am dissatisfied with. Any suggestions?

No it's not a misprint. Got the build out specs straight from Dodge. I know that isnt a very good set up. That change would be well off into the future. Like I said, just wondering if this would be normal performance for this truck or is there something else I should be looking at.

Its interesting about your problem as that I have the same, except mine is a 98 1500 with a 3.9L engine. As soon as I shift into 5th, I can maintain speed and slowly pick up but if there is a strong headwind, forget it. Along with that problem, my temperature gauge also rises! When I shift back down into 4th, the temp goes down. Too add to that, my thermostat is a 195 and it makes my running temp around 215 continuously on the highway. So I am just now trying to figure this out. Any thoughts there? If I figure out anything I will post it here.

My 95 5.2 5 speed does that same thing except with a head wind there really isn't much of a loss. I can climb a hill on the highway with not really much of a problem but it just seems that there isn't much power. I just shift because I try to run a continuious speed and keep away from other drivers. Hopefully it is just to high of a gear. Other than that I don't really have much of a problem. The truck runs great.

I agree with Socha, you are probably undergeared. What kind of RPM are you running at at highway speed?
My overdrive is nothing powerful either, but I did notice it improved when I changed my gears.

I have 265 75 16 tires on the truck. It came with BFG AT's. I will probably eventually switch to more of a highway all season truck tire, but these still have a decent amount of tread on them so I don't see a need to do that now. At 65 in 5th gear I am not even at 2000 rpm. Based on some of these other posts it looks like the gears are the main problem. I am assuming that a better exhaust, programmer, and maybe a new TB would help some? What should I expect to pay to have some new gears installed?
