    Greetings,

    I have purchased a 1996 international 4900 DT466 w/Automatic transmission 100,000mi paid 5k

    This is my first commercial vehicle though I have always worked on my own cars and trucks. I have been driving it for a few months now getting a feel for it, and I have more questions than I can probably remember to mention here.

    When i got it the front driver leaf spring was completely severed, got a replacement at a salvage and I was on the road. it has a reefer box but no reefer unit.

    I'm about to make my first long trip soon an would like to do some routine maintenance.
    A close look at my transmission case and I see I'm leaking fluid out my rear seal.
    Oil looks used and I'm sure needs a change and filter.

    I cant find a service manual for this thing anywhere.
    1. What weight of motor oil and how much? (moving to Minnesota)
    2. What kind of tyranny fluid and how much?
    3. When and how often should I bleed water from brake lines and fuel?
    4. should I change rear Differential fluid?
    5. how do I find out what transmission I have and where do I get this seal? (how hard is it to do)
    6. for jacking up the truck will a beefy bottle jack do? (20ton)
    7. If i wanted to check my brakes, Is a impact gun required or can i get by with a breaker bar?
    Any other thoughts or comments?

    1- 15W40 oil for diesel engines. usually around 26 litres.
    2- This will have an Allison 2000 series in it. Usually synthetic Allison approved, not cheap. No sure on capacity, but I think around 14 litres?
    3- Check for moisture every day with a new truck until you are confident it stays dry. It should not be wet, if it is the air dryer is not working. Fuel, get fuel at reputable fuel depots. Usually nobody drains a water separator until it is filter change time. If you are getting that much water in the fuel system, then you are getting bad fuel.
    4- Take a sample from the bottom plug. If it looks like spoiled chocolate milk, then yes.
    5- If you give me the last 8 digits from your VIN I can see what the truck was built with, but it probably has an Allison 2000 series. The seal would available at any Allison dealer. I would recommend a professional for this due to seal installing tools needed.
    6- Yes, use jack stands too.
    7- Yes, you need a 3/4 or 1" gun to break those nuts loose. They are torqued to 450-500 foot pounds of torque when installing, but usually harder coming off due to rust!

    I am not familiar with the area, but check your local listings for a reputable shop that is an Allison Transmission dealer, these are usually the major bigger truck dealers. Since your truck is an International, I would recommend the local International dealer. Most of them are also an Allison dealer too.
