    Welcome to my world hehe,I bought my 02 in nov 06 feb 07 and 4k miles later trans was toast now I am down again for same reason BUT I was smart enough to purchase an aftermarket warranty from the used lot which cost me $1500 first rebuild was $1800 to them and $100 to me this time I am going with a beefy trans and will pay the diffrence out my pocket beacause next time a trans go I would be out my warranty

    I don't plow in 4x4 unless I have no traction and in drive only very low speeds

    Have a trans temp gauge already I am getting a deep pan soon too

    What did they quote you to do the rebuild? A new tranny straight from Chrysler is just under $3k installed and you get a 50,000 warranty with it.

    After this plowing season I'm going to have mine rebuilt because I have abused it since the day I got it. I plan on spending around $2k because I'm going to install upgraded clutches and a larger pan.

    Im not suprised that these tranys cook out on our dodges and other brands to.I watch the trans gauge like a hawk :dizzy:and on the 1st push 50 feet of heavy stuff it will spike to 200 deg in 4 high.
    But in 4 low i can push a mountan of snow for hours and the temps run nice and cool.
    All auto trucks should come with a trans temp gauge on the outgoing line to the cooler for accurate temp monitoring.Its a cheap way to make the tranny last a long time.:drinkup:

    I have 01 that the tranny whent out @ 120,000 miles. Lasted 3 years with a plow. When I had the tranny done, I went with a DTT tranny. $8000.00 later the tranny will handle anything that is thrown at it.

    Bought an 05 3500 brand new and tranny lasted 75,000 miles, truck now ha 150,000 miles on it and tranny getting ready to go again. This time it will be replaced with a DTT tranny just like the other one.... Here goes another $8,000.00

    wouldnt get going fast enough to hit OD anyway.

    if your going to spend the money get a built tranny. from Gorends or suncoast. if one from DC cost $3000 and youll have the same weak tranny. get a good one add a deep pan with amsoil trany fluid and a temp gauge. you will be set.

    let me know if you have any questions.

    I have had a few dodge trannies rebuilt. If you have a good local shop that knows what they are doing, you can get a good unit. The best way is to buy a suncoast or DTT or something along that line, but money is an option. The best place to invest money on the rebuild is in the torque convertor. That is the major down fall of these trannies. After that is a shift kit and a heavy duty cooler. These convertors are very sloppy, and that is what causes a lot of heat. I hope this helps.

    What's a Cummings? I've heard of Cummins, before.

    What does driving in 4WD have to do with cooking a tranny?

    The Dodge trannies are a known weak spot, for the most part. Get a good aftermarket one, they can be built strong, and you won't have to worry about it again.

    Just out of curiosity, what good does a piece of paper that says my tranny will be rebuilt under 50K at no cost at 3 AM in a blizzard? When there are other options available?

    Check out TDR for more info on a good tranny.

    I work at a dodge dealership we get cummings and hemi powered rams coming in all the time with fried transmissions. Its crazy. My friend has an 04 diesel and he blew the transmission up and he can tell the one that was put in by my dealership is going too and hes only got 34000 miles on his truck. I also just did both front axles and hubs for him $4000 in parts.. thank god he has a warranty.. If your under warranty have the dealership do it if you aren't just get one made super strong for your needs. By the way my friend plows so that why theres so much more wear.

    I have a Question:

    At what temp. should I back off on the plowing?

    When we all say that this tranny Is the week link...Would I be wrong saying that's Its the week link, because of the high amount of heat It produces?

    By the way the truck Is still In the shop.

    you should really get a deep trans pan and some good amsoil atf for your new trans. it will help with the temps as well as other things.

    trans tip

    I was told early in my plowing days, to never shut the truck off if you can.. keep it running to let the engine and tranny cool down.. Hope this helps those just starting out plowing...

    1- A lot of failures have to do with the operators as well, are you stopping before you put it in reverse and backing up, even when you think the wheels have stopped moving forward bump it into N for a sec, then Reverse, makes a big differance. I have a friend with a 3/4 for with 351 W and he slams it into reverse before he even comes to stop, he says his production allows for the cost of a new tranny each year, but I don't buy it.

    2- RUN THAT TRANSFERCASE IN LOW RANGE!!! This has worked for me over the years with the old 1st gen trucks. If you have 3.54 or 3.73 gears you need to do this to make the tranny live!

    x2 on the Temp Gauge, Deep Pan and Big Cooler!
