    Old dog, new trick! 1 year cdl A. 95% in an automatic trans. by chance. 5k miles in a 10 speed. (Freight shaker, International, and Mack)
    NOW, day TWO in a 13 spd with a splitter!! FIRST thought:WTH!
    One super quick 5 minute video search crash course and I was on the road with a few minutes to spare on tthe schedule.
    Question(s)- * Oh, It helped to think of it as a 9 spd with low/hi on the top 4, rather than a 13 spd...didn't know what gear it was in for a few go rounds! I drive at night.
    So, still ruff downshifting from 5 to 4 (learned first go round while turning in an intersection to NOT downshift while in high splitter!) Still, had to fully stop though. Practice, practice.
    While at speed in 8 hi (13), going to 8 low, to 7 hi, back to 8 low and hi, why did the splitter grind the gear? Up/down, did i skip a gear while splitting. Do you mash the pedal to actuate splitter? Can you not coast in gear (no throttle), and still split? It dropped to neutral one time and didnt want to take either gear without shifting, by the time I needed to grab down to 5th.
    Trying to solve these issues. Boss is ride-along co-driver tomorrow.
    Also, i learned to drop cruise control before shifting at all! Double clutching just to force the memory retention, but I'd rather float 'em. Fast tracking the learning curve.#foodontheplate

    When splitting the gears with the red knob, let off the fuel for a quick second and get right back on it it, it should shift. This is the same going up or down. As far as the grinding, could be that you were late burping the fuel, or just older equipment.

    If you’re downshifting with the splitter you can clutch or just rev the engine and it should go

    If you’re just comming out of an auto I’d suggest just acting like it’s a 9 speed and only splitting the last gear till you get more time with it
     
    Lav-25, Diesel Dave, mitrucker and 3 others Thank this.

    You go through every gear to stop? I, and I think most but probably not all only slow through the high range side. Every now and then, but very seldom did I downshift through all the low range gears to come to a stop. I drive an automatic now, and hate every minute of it.
     
    Rideandrepair Thanks this.

    When downshifting to make a corner, don't drop out of high range (the front switch), use the cheater gear (high range, left and down under reverse), it's the same ratio as 4th (low range, far right and down).
     
    lester, RockinChair and 201 Thank this.

    Dont worry - going from 13 spd to now an 18 spd. I still couldn't tell you what number gear im in but I k now exactly where I'm at and what I need to do next. Never paid much attention to what number the gear was
     
    wore out, DannyB, Lav-25 and 6 others Thank this.

    I'd never bother downshifting with the splitter. I just do full gears. Usually I find bottom gear in high range is a bit much so I usually drop into top gear of low range when slowing down.

    Yeah just split the top range gears. Leave cruise off as much as possible when the boss is riding along or remember to disable it before gear shifts if you don't use the clutch pedal. When I got my first 13 speed after spending the last 5 years with automatics, it took me a while to get the hang of it again. Don't have the expectation you should be perfect. Accept you will grind gears and get over the noise until you have the thing whipped. What I did was deliberately upshift and downshift using the (hi/lo) splitter or direct/overdrive splitter of the top gears just to have the practice. Like you climb a tiny hill and about the time you almost get to the top the rpms could be at the low end of ideal, but I'm now on level ground and could just stay in current gear, but decide to downshift half a gear, from overdrive back into direct or from hi to lo without throwing the stick. and when I was on level ground in high lift a bit on the "gas pedal" and let road speed drop a little and downshift from hi (overdrive) to lo (direct) without moving the stick. The idea was to just maximize the number of times I slid the hi/lo switch, lifted off the gas and replied the gas to cause a shift. Over and over and over until I was more comfortable. Then do that to down shift from whatever max speed top gear I was using until the last position above the highest gear in the low-range. Once I preselect for low-range I stopped using he direct/overdrive or hi/lo splitter and went back to shifting like any 9 or 10 speed, other than Super 10.
