    Remember the 5s helped me out a lot the last time I was road testing in a manual. Of course after all that, the company put me in an Automatic lol.

    Also, when I ground gears downshifting, I think it was because I had a tendency to over rev.

    Does having the engine brake on make it harder to shift?

    For the inexperienced, yes. The motor speed will slow down crazy fast.

    Not to say you can't learn it like that. you would have a hard time without the engine break on if you did.

    Once again,in my experience it can. Depending on the trukk of course. In my current trukk it does not. Drove a rolling wrekk when I first started driving and the engine brake would be on all the time when engaged. Just had to give it a few more rpms and hit the clutch at the right moment. Bam. Like a hot knife thru butter. The fan can also play a part sometimes when climbing and downshifting. For me I just gave it a little more juice. As stated previously in this thread every trukk has it's own personality.

    That is not recommended for inexperienced.

    The engine RPMs will drop insane fast.

    It's used once in a while when you need to sprint away from say a rail crossing. You can slap stage three on, start grabbing gears while slamming power. You cannot miss a gear doing this or release clutch too fast.

    There is a point at high RPM on your engine where the transmission will simply fall out of the gear (Once it is used up so to speak) and you will come off the hammer and make it snort down to torque. You can slip the transmission shifter into the next gear up and add fuel.

    It's a form of floating and that is another issue against the inexperienced but for me it's one way to keep up with the drop in RPMs's that fast.

    I don't recall doing that particular type of shifting more than a handful of times a year. It's not a stunt, but at the same time it can be abusive to the truck. However it's done once in a while when you need to say get the trailer quickly out of a spot such as a rail crossing.

    The drivers that constantly do this are showboating and at some point they will find it a expensive habit when the shop gets a hold fixing this fixing that and other stuff.

    Ok, I’ll bite. What’s with the odd aversion to words ending with “ck”?

    Only if you let off the gas enough to make them hit.

    Having the engine brake on is sometimes NECESSARY to shift a 13 speed, 18 speed or super 10 when climbing a grade.

    It's a trendy millennial internet meme thing.

    What you're describing sounds very abusive, to everything. I've discovered if you let mine wind up just a little over 1800 you shift smooth as a hit knife through butter and twice as quick, and then it only drops down to 1550 rpms or so. What I hate having to do is stop on a slope because the construction crew hasn't figured out they should put the flagged anywhere but there, including 5 miles further back.
