    Ok, so far, nobody on the net has been able to tell me the optimum rpm downshift for these tandem axle flat-decks. What I have found by trial and error is that these trucks like to up-shift between 2300 and 2500 rpm without any grinding. As for downshifting, they don't seem to like any type of rpm and seem to only want to downshift when the entire truck is standing still. Perhaps this is because of the engine as most say the eaton/fuller 10 speed likes to up-shift at between 1500-2000rpm despite this model truck wanting 800 to a 1000 more rpm before it will up-shift smoothly. I will try to downshift at 2000 rpm from 10th to ninth and see if that works. I kind of doubt it as these internationals seem extremely problematic to me. A co-worker told me it "took me forever to get the correct rpm for downshifting on these 4400 DT466 tandem axle trucks."

    Let's make this simple.....

    Treat a truck like you would making love to a women.....

    When it's ready...it's ready....

    If you can't shift with two fingers and you have to "force it in"....You ain't doing it right.....

    You can't manhandle a lady and you ##### sure can't manhandle a truck and expect it to work properly.....

    i agree with workin class. i drive brand new full size pete with the ef 10 speed. up shift between 1300 n 1400, depends on the grade but always right there. down shift when it drops under 1000rpms. the lower it gets the more you can drop at once. i always come down 2 gears around 700 when the truck starts to act up, the higher rpms that it falls into slows the truck really good. if ya got any questions im me.

    I'm having big issues up shifting on a 5-6% grade from a stop at traffic lights on the road test route. The lights are about 3/4 of the way up the hill, and when I start out in 2nd I can't seem to get it in 3rd or 4th. I rev to 1500 like my instructor says but it never works. I'm not sure what to do. Starting out in 3rd is really tough on the clutch and staying in 2nd will definitely get me demerits on the test. Any advice?

    2nd won't get you demerits if you are empty. If you are loaded on a hill then you might want to use 1st. Remember you are matching engine speed with road speed to get them two transmission gears turning the same speed so you can slide them together. Starting on a hill you loose road speed quicker. That said, rev a little higher to compensate. More like 1600-1650. The opposite starting going downhill, your shifts will be lower rpm because of the hill helping you roll faster. That'll get you started and when you get experienced you'll learn more.

    Thanks for the advice. I meant crawling through the intersection in 2nd with a column of pissed off cars behind me. I should have been more clear.

    Uses the clutch brake to stop the transmission input shaft. Hit the floor with the clutch for a split second just before selecting third gear, etc. The clutch brake is designed for that along with selecting a gear at a dead stop. The clutch brake will not wear out with this procedure because the transmission is in neutral.

    I just finished Truck Driving School. There we drove a Kenworth T2000 sleeper with an Eaton Fuller 10 speed. We learned "progressive shifting". We shifted into 4th gear at 1000 rpm and shifting to each gear after that you increased 100 rpm until going into 10th gear you were at 1600 rpms. Downshifting was at 1000 rpm for each gear with about a 400 rpm rev at the "door" of the gear. (We were pulling an empty 48' van)

    At work they drive International Prostar day cabs. When I first got in one I immediately noticed when shifting I had to increase the rpms when shifting up. It's a slight difference and it *seems* shifting up every gear is at 1500 rpms. When downshifting it *seems* 1200 is optimum with a about a 400 rpm rev going to the gear.

    Any Prostar drivers out there care to advise if that's correct? I don't have my license yet, but I have my permit. When I test, I don't want to be scraping gears. I know it happens sometimes but when I test I don't want it to happen.
