Long story short Ive been OTR for about a year doing flatbed but the trucks I've driven are all automatic. The jobs I'm looking at transitioning to use primarily manual transmission and im a little leary about it. I own a manual transmission car and passed my unrestricted CDL course so I understand how to shift up and down. No big deal there. My question is what to do when slowing down quickly and moving again. The gears are so short in a semi, how do you decide which gear to be in while still rolling? Example: you're driving at 65mph and have to slow down to 35 quickly. What gear should I be in?

MOST IMPORTANTLY having experience shifting gears in your personal car will make it MORE difficult for you to learn to shift gears in a truck. The clutch in a truck is used VERY differently than in a car. In a truck you only press the clutch down "to the floor" when you are stopped, never in motion. Re-read that sentence over and over, if you need to. People with ZERO gear shifting experience in any vehicle learn faster than people with car driving gear shift experience. Either way a few hours is enough to get you on the road.
EVERY newbie pushes the clutch too deep when they shift in a truck. You should use just enough clutch to let you pull the gear lever out of gear or put it into gear. Your car experience has cemented in your mind "clutch is all the way up or all the way down". That DOES NOT work in a truck. The shift pattern isn't difficult. Many of the transmission use a simple H pattern with maybe one more leg added for reverse or lowest gear. Remember, the clutch goes all the way to the floor only when stationary, like preparing to move from a dead stop, or changing from forward to reverse direction. If you try to use your car shifting technique in the truck you will have a hard time ever getting into gear because when you push the clutch too deep it activates the clutch brake, which slows the engine RPM. Shifting gears in a truck is all about matching engine RPM and the gear you use. My 9 & 10 speeds usually had a pattern where each of the gears in the low range were good for about 2-5 mph of road speed on the speedometer. IN the high range the gears were good for about 5 mph. Once you see the pattern in your truck is helps a little to know what gear to be in just by looking at your speedometer.
There are a lot of videos from truck driving schools on YouTube showing you how to shift a 9 or 10 speed (the most common transmissions for rookies). Watch them over and over.Last edited: Jun 12, 2024

Also, you will have problem downshifting for slowing down or climbing hills. Everyone does. You will be shifting like a pro very soon and still having more trouble downshifting then you think you should. Remember you maybe shift gears 3,000 times per day and only downshift 5-10 times. It's normal. PRACTICE PRACTICE PRACTICE. EVERYONE can learn this skill. You aren't any worse than the worst person earning a living right now.

Your experience shifting your 4 wheeler will hinder, not help, you shift your big rig.

If ya can't find them,grind them. Seriously it just takes miles. No one was an expert at anything to start with. Good luck driver.

Time...after a while you will manage the slow down, glance at the speedo and automatically know what gear.
Take note of your speed as you are ready to shift up and you will start to figure out the speed range for each gear and it will become rote memory after the first 100,000 shifts or so.
Shouldn't take all that long just don't floor the clutch when moving, a quick stab on the pedal is all it takes.
Then you will have the basics to learn to float the gears..............Lav-25 Thanks this. -
