    Hey truckers.

    So I was on a company road test the other day, for a good local job... and I was floating those gears like a pro. I impressed the hell out of the road test examiner...

    ... ... until I came to a stoplight that was right at the beginning of an overpass.

    So I put it in 3rd (I was pulling a set of empty double flatbeds) and start accelerating when the light turns green, and when my engine is whining and it's time to upshift, i'm already ascending up the overpass. i push it out of gear, let the RPM drop a bit, and when i try to push the stick into the next highest gear, i'm met with not being able to stick it in the gear. at all. i try again. losing speed, losing RPM, lost my gear, losing control. i eventually come to a dead stop and hold up the already pissed-off line of traffic behind my rig.

    it's not good at this point. the road test guy is severely irritated but understanding. 'it's all right bro, we all make mistakes' he says. but i'm really screwing up. trying not to roll back. with a little bit of luck and help from the road test guy, he forcibly shoved the stick in the correct gear, almost raping the transmission, and we keep going.

    "so how did i do?" i ask at the end. he said , "you were good bro, except for that over pass."

    In the end i got offered the job...

    but i am a rookie driver with about 6 months having my class A license.

    So what did I do wrong here? Are you never supposed to float gears on an incline? If i double clutched that, would I have not lost my gear? this could be very dangerous if I don't figure out what I did wrong :\

    You just have to be quicker shifting gears uphill since RPMs drop faster and also rev the engine higher... you should've double clutched since you were with the instructor, but you got a job. It'll come to you with more experience. Good luck

    If you miss a gear while floating, never be afraid to mash the clutch. One thing to remember is you need to get your RPM up to match where it should be if you were in gear, usually around 12-1300 on the low end in most trucks. the longer you wait and the lower the RPM drops, you have to hit the accelerator a little more.

    from now on, I'd say if you're on a hill, use the clutch until you get a little more practice with floating on inclines..Don't forget you were empty in this situation. You'll lose speed a lot faster when you're loaded so its a little more challenging

    What Boka said.. everything speeds up on an incline just like a decline (when it comes to shifting)

    Gravity doing what gravity does, nothing more, nothing less.

    Floating on a hill, I'll manually engage the engine fan. The engine rpm drops faster and you can upshift quicker. For extremely steep inclines and heavy loads, I'm told that shifting with the engine brake is a good option. But I haven't perfected that method yet.

    Mistake was simple just shifted to slow usually on a incline you don't wait till the rpm drops you just make the shift gravity usually takes care of the rest better to get a lil grind than miss and lose control of the gear box atleast that's the way I look at it brew shifting with the jake on isn't a good idea especially on a incline/heavy load would make the truck stop even fast I hope you were only joking if not someone was pulling your leg

    ... or you can use the clutch and shift like Eaton-Fuller, the maker of the transmission, recommends. OMG, did I just say that? The horror. Come on people, it's OK to use the clutch in a shift, up or down. I promise you the world won't end, and nobody will make fun of you. Geez.
