    I have an 03 Cummins that was originally a Canadian truck and I have drove other 03's and my WTS light seemed to not be staying on for the right amount of time, it comes right on and stays on for about 4 dings the truck makes when you first turn the key and will start right up. Now the temperatures are starting to drop and when I went to start my truck the other morning it was about 42 degrees F but it is still only staying on for 4 dings and it still starts up but I know that it should stay on longer than that with it being cold because when it was 92 degrees out it was staying on for 4 dings so I know that with it being 42 degrees it should be staying on longer so what …

    Every website has an opinion one way or the other on the trans heat exchanger. So, what is the consensus here? Do I replace it or delete it and put a under bed cooler on it?

    Last Saturday while I was at my retriever clubs upland training day, I saw a part on a Dodge gasser that I thought I could modify slightly to help block off more of the front of the truck. This part goes in the opening below the front bumper step pad and the chrome bumper itself. It's black plastic that fits into the opening where my tow hooks are at. Between the tow hooks on my truck there is a wide open area to the radiator. Even with my home made winter front, there is still a big opening in the front of my truck. The truck that had this on didn't have tow hooks, but I thought I might be able to cut holes around the hooks to mount this in there. I looked in the manual,…

    I bought a Trinity T1000 for my 03 ram 2500, to save a few MPG and change the parameters for tire size, and I just found out that the T1000 can not do it. Is there any tuner/programmer that will change tire size paramters of a 03 or is this hopeless? Thanks for the advice!

  7. I've read that these are actually 3/4 ton trucks. Having said that I found one for sale that I'm going to check out soon. How can I inspect the truck to tell if it's actually a 3/4 ton or a 1/2 ton? I've heard you can count the lugs on the wheels and look at the axles and suspension but I'm not sure exactly what to look for. I meant 3rd gen. The 06-08 models.

  9. I have a 2004 ram 2500 slt 5.9 automatic. Truck has ABS code 84 Vin Mismatch. ABS and Brake light are on and of course ABS does not function. No other codes in the truck at all. Every place I have called which repairs ABS modules, says they can not repair that issue. Chrysler discontinued the part. Supposedly it needs programmed. Local dealership said they can not re-program the ABS module. I have read you can swap it out with one from another truck as long as the part number is the same. I pulled one out of a truck my neighbor has and the part number is the same. Issue is still present. Anyone have any input on how to resolve this issue? Checking …

    my truck recently started getting "stuck" in 2nd gear. @idle the truck will have a slight vibration when it is going to do it, during light acceleration the truck stumbles or misses and approx the time you reach 17-2000 rpm and release the accelerator the truck stays @ approx 1500 rpm until the tranny is shifted into neutral or it corrects itself, under heavy acceleration the shudder disappears however if acceleration is heavy once it is stuck there is a rapid clunking sound that i cannot pinpoint its origin. Fluid level was low, within the safe crosshatching, topped it off, have tried tow mode with no change. I've read several posts on the gov press solenoid and switch,…

    I went up to Black River Falls, WI to guide some "pheasant shooters" for a member of my retriever club this past weekend. I was pleasantly surprised by the ground cover at the hunt club and by the shooting of the shooters. Anyhow, it's about 225 miles from my place to BRF. I filled up the night before I left, so I had a full tank of fuel. Probably 200 miles of that is interstate which I drove at 2000rpm or about 68mph. Once there at the hunt club there was some short driving to the leased farms to guide shooters. There was also driving to and from the guide bunk house which was about 20 miles away.Long story short, I got back Sunday afternoon, took yesterday off because o…

    My truck is running rough and has a miss while idling and accelerating. I have done the 3 key rotation and it is displaying 3 codes, P0521, P2146, P0201. I changed the oil pressure sensor last night hoping that would solve the one code! Thanks in advance! Any help would be appreciated!

    The tilt wheel on my 2004 3500 is no longer working, it’s stuck in the all the way up position. I have watched a couple videos and know it’s the plastic part on the column that is broken. I can’t find the part anywhere? Can anyone shed some light on this?

  18. Hey there gang... I ran into a clunking noise that was associated with the track bar which we can see the bar moving. After inspection of the bar which Mark did for me. Come to find out that the track bar was not properly tightened last time it was installed. It managed to wear a little bit and was banging back and forth on the bolts. Bushing appear to be fine but was capable of moving just a bit and making a clunk. Now after just looking it over and reinstalling and getting the bolts tight, the clunk is gone now. Thor is going to be hauling a trailer today and then returning. My renter Mark is going to make the run for me so I can handle chasing parts for th…
