    Super 10

    Hello, I just bought a used pete 379 with a super 10 trans and wondered what the professional's recommend on how to shift. I'm hearing different ways like leave the shifter in the hole and switch the button and some say pull the shifter then move the switch. Also what are the correct rpm's to shift. Any tips or suggestions? I also have another truck with a 9 speed and have not had any issues with that one. Once I have become familiar with the super 10 I think I'm gonna like it better. Thanks

    I've never cared for the super 10. I can drive them, but don't care for them. Give me a straight 10 or a 13.

    What worked for me was to start out in 1st split to 2nd. Preselect the splitter back to low, shift to 3rd, split to 4th. Preselect back to low shift to 5th split to 6th....................... continue thru the gears. Same for down shifting.

    if you have ever driven a straight truck with a 5 speed trans and a two speed rear end, the Super 10 runs on the same shift pattern. Whenever I drive one, I simply preselect the next gear using the flip switch momentarily before moving the lever. They are the same basic transe as a regular 10 speed. If you do a lot of highway driving, you will find that the ability to switch between 9-10 without any stick movement can be a nice feature. They also provide the basis for the Top 2 style trans with limited autoshift capability in the upper two gear positions. Try it for a while, and you will probably come to an agreement with using it.

    I promise you will like it better once you get used to it. The super 10 is called the lazy mans transmission. Which is why i like it so much LOL The biggest think to remember is that you cant speed shift it like a regular 10. The rpms must come down for it to drop in gear mainley when splitting. I always leave the jake on low till i get into 8th gear then shut it off for the last 2 gears. This doesnt mean i let the jake kick on while shiftiing every gear. It is on in case i dont let rpms come down. The jake is mainly nesescery when taking off on a hill with a load on. It brings the rpms down before the truck slows down to much because you cannot speed shift it. I repeat "you cannot speed shift it" You can preload the splitter every time up and down shifting. You gradualy raise your rpms with every gear, the higher your rpms in the lower gears, the longer you will have to wait for them to come down. The only time i ever had problems is when i pulled a chemical tanker, if you split when the liquid hits the back of the trailer it will stop you dead in the road if going through the lower gears. I learned to estimate when liquid was gonna hit the back and not shift at that exact moment. Ive had drivers that never drove one before catch right on and love it, then ive had drivers that just cant seem to get the hang of it. I think mainly because they try to speed shift it all the time. I hope this helps !!!

    I have a trick that helps smooth split shifts, and speeds up the shifting process. It is a little extra work, but the shifts sure are smooth.

    When splitting the gears that you don't move the shifter (3/4-5/6 ect...) I will pre-select, release the throttle, and at the same time move the shifter to netural. At the appropiate time I will then move the shifter back to the gear I just left.

    I know this sounds dumb, but the transmission sure shifts faster and smoother this way. You also have the plus of the splitter gears not grinding away while waiting for the transmission rpms to drop to the correct speed.

    The wear on the splitter gears won't bother most company drivers, but for an O/O, any transmission wear that is prevented is money in the pocket.

    The splitter gears are usually the first thing to go in a super 10. This is from the non-stick splits that cause the splitter gear wear, especially when the throttle is pressed before the gears fully engage.

    We ahd the truck about 6 months... Spouse did fine with it. I didn't. I've always been able to drive anything..not this. Must be some kind of brain damage. Anyway, we'll never have another.

    That's the way I was taught. But I hate super 10s. Just not enough work for me I guess. Hubby swears by his. He can have it, gimme 2 sticks anyday.

    From my own experience super 10 trans. are cold natured they are hard to split when cold, the way I would split mine was every time I would first take off instead of pre-selecting 2 gear I would take it out the hole,split it ,then put it back in the same hole . I would do that for the first 2 or 3 holes by then it would be hot enough were it would let you split it in the hole . I realy liked mine ...............

    Do you know that the Eaton website has instructional videos about many of their transmissions? There's one on the Super 10, might be helpful. It's under "Transmission, Heavy-Duty, Manual" then "Operation/Driver Instruction". Here's the link.
