If it was that then it would throw a code I'd think. I'm going to guess you have something in your tank and its getting sucked down when you try to power through stuff. I'd put a new fuel filter in and put something in your tank to try and dissolve whats in there. If that doesn't work run the tank till its dry and take it down and see whats in there.

I would take a look at your fuel injectors. my truck did a very similar thing. felt like i had now power when i was pullen a big hill. it also clunked almost like the tranny was sliping. cleaned the injectors and it instantle went away.

If your going up the hill in 2nd on those autos it will stay in 2nd gear. The tranny won't downshift. It will also start out in 2nd gear kind of like a 5-speed. So that could be what your problem is. It also sounds like it could be a bad torque converter.

I replaced the tq converter about 4 months ago. i tried in 2nd and in Drive both had similar outcomes.

guys at work think it is a fuel deliver problem as well.

I just went out and floored it ran up to 5500rpms shifted through all the gears up to 90mph without a glitch... So I am confused seems like it should act up there.

I still think its the fuel injectors, my truck ran great throughout the power band until i hit a big steep hill or other high load situations then it would spudder and act gut less.

Try some fuel injector cleaner you put in your tank and see what happends.

Also try some gas de water stuff.

I had a hard time starting my quad as well until I used some stuff that take water out of the gas. And then it started right up. Never know you might have just nasty stuff at the bottom.

In fact I wonder if this is why mine does it? hmmmm

BAD IDEA, that lucus stuff is what cloged my injectors in the first place. the STP stuff is the only thing i have found that actually works. you physically need to take the injectors out and clean them.

hope that lucus stuff dosent mess your truck up like it did mine.

Lucas Oil products are the best products on the market. I don't think it was the fuel treatment that clogged your injectors or caused you problems...


Here is a way to test some things out. If it dies under load, then put your trailer on the truck and get a slow roll going and then stomp on it. See if it does it since it will be under load. Do it on the road in 2wd and then do it in one of your fields (if you have room) in 4wd.

It might be a bad solenoid not allowing the truck to shift (maybe I have no idea about auto transmissions).

Check to see if there are any transmission codes in the PCM. Remember my truck wouldn't shift on the way home from Michigan and it didn't throw a code. That might help you determine what the problem is.

Use seafoam in the tank (always worked for me). I also think its fuel, clean the injectors and what about the fuel filter?

Zack, what if you loaded your trailer and tried yankin it around at home? That would duplicate the load, thats for sure....

I can't hook the trailer up any more, leaf springs wont support it.

I will just see if firefighterjosh can bring his truck over and i will tow it around.

I had a similar problem with my 35's and stock gears and my 5.13's and 41's.

I can spin the crap out of them, but once I actually got in a mud hole or what ever, I could not get the truck to rev about 4k. I'm hoping I won't have that problem with 37's and 5.13's.

oops!!!Stomping the pedal all the way to 90 would more than duplicate your load of going up a hill in 4lo. Something in your tank or clogged injectors only when you are in 4wd don't sound right. I think that it is an electronic problem in the tranny

I would say fuel filter or injectors, if not then some type of sensor possibly.

Hmm.. It doesn't do this in 2wd at all and only in 4wd when under a load?

If the problem doesn't replicate in 2wd, its NOT a fuel issue at all. The ONLY difference would be the T-Case involvement.
