    i have a 2006 2500 with the 5.9l diesel. to shift from 1st to 2nd i have to let off the accelerator then slowly press it to get into 2nd gear. on flat ground the problem is hardly noticeable, on hills though it seems more present. im wondering if anyone can give me any type of insight, its been doing this for a year, w/ no sign of a real transmission problem. im wondering if maybe the shift points got changed when the superchip was added (im not the 1st owner, and didnt install the programmer). also, the truck only has 96k on it.

    also, any sites that might have better info on this?

    Does it not still have factory warranty? take the programmer off and take it back to the dealer. my buddys 05 was doing the same thing but worse then yours something with the bands in the tranny were shot they did a full rebuild.

    There are all kinds of fuel additive with Howes being one and a lot of people use Power Service.

    Have the dealer scan the computer to see what has been done to the truck.

    Seems that alot of people on cumminsforum.com had a similar problem...... If im not mistaking its a bad sensor on the tranny that causes this problem..... cheap fix.

    I assume it's an automatic, mine did it for a bit...

    You have to get up underneath the truck, and back up under there where
    the transmission is exists a linkage with a steel rod (I think it's steel, could be
    hard plastic too) and anyhow this rod moves through an assembly allowing
    the transmission to shift.

    Matter of fact it's a steel rod moving through a black plastic thing.

    WHEN that rod / assembly becomes caked up with crud it sticks, and you have the problem.
    I simply sprayed mine with plenty of some kind of cleaner (don't remember, carb cleaner or something)
    and lubed it lightly with Wd-40 or liquid wrench or something....
    Anyhow, sprayed it good and clean and lube.

    Might have used a rag / compressed air as well, it's been a bit.
    But you have to take care of it, the problem WILL get worse in time.

    I believe, if I remember correctly, that the thing is connected somehow to the throttle cable,
    I can't remember exactly as it's been a few years but I would look for something that moves
    in response to throttle pressure, that should help you locate it.
    Mine was on the driver's side of the transmission, again if I recall correctly.

    Haven't had a problem since, if you absolutely can't find it let me know and I'll see about taking a picture.

    Sounds like the governor pressure sensor/transducer and solenoid. When those two things start acting up it can screw up the 1-2 shift. It's a pretty simple fix though. Go read this thread.
