Eaton fuller 13 speed

I often shift progressively through all the top gears. Honestly, I think it's just a matter of getting used to it. I'd like to tell you how, but I don't really think about it - I just do it. I will advise you not to take instruction from another 0-1 year driver, though.

Are you simply asking how to go from, say, 8H into 8L? You just pull back on the button, give the accelerator a little tap, let off of it, pause (sometimes you'll be able to tell when it engaged the gear, sometimes you'll have to know how to time it), then put your foot back into it. There's no need to use the clutch for that.

 

I never split til I'm in the high side no reason too I've pulled loads grossed at over 100,000 in a 460 Mack and never needed to split til high side

 

dont split any until the top 2,just shift normally it'll come to ya soon enough,hang in there and have fun with it.

 

13 speed is my favorite you'll love it once you get use to it but I have to disagree with only splitting the top two for example if your fully loaded pulling a big hill once in the high side you can start splitting and you'll never lug the truck and will keep pulling

 

All shifts whether button or lever shifts are pre selected usually. So once youre in 7 high, just pull the red button back. It will not shift until you let off the throttle or break torque.And just use speed/rpms or listen to the motor as you'll be able to tell when it wants to shift. Ease out of the throttle a tad, rpms should drop a bit and then ease back into it. Simple.

 

If you were used to shifting with a dead weight load, learning to shift with a live or liquid load can be tricky. You either need to wait a long time for the surge to finish or be very fast and get it done before the surge has time to hit the bulkheads. Im not sure why it would only happen in one gear tho.

 

What you might do, as the poster above suggested, is wait. You might be trying to shift mid surge and then getting caught with increased rpms when the surge hits front or too low rpms when the surge hits back. With no baffles, you need to really make slow easy movements/acceleration/shift.

As others have suggested, just drive it as a 9 until you're comfortable. If you're having trouble I wouldn't suggest trying to "learn" while going uphill or downhill, as that would be the worse time for you to be "practicing" and lose it.

Good Luck.

 

Shifting those half gears with a clutch is pretty hard to do because of how fast you need to move it. You are only talking about a change of about 200 RPM (unlike the 500 RPM or so of a full gear) so by the time you clutch out and clutch in I'm guessing you are dropping too many RPMS. To test that theory get to the point when you would like to shift and then move the splitter to the LO side and then immediately take pressure off the throttle and slide it to the next gear with no hesitation. It should slip right in. When downshifting it is the same principle, just get to where you want to shift, slide the splitter to HI and move that stick to the next lower gear. You may need to up your RPM slightly but practice a few times and you'll get it. I drive an 18 speed and very rarely clutch those half gears.
