At what RPM should you shift gears in a semi truck?
Each truck is different, depending on it’s equipment. For the higher gears, add the two digits of the speed and that tells you what gear you should be in for 1300 engine RPMs. For example, at 15 MPH, 1+5 is 6, so you should rev the engine to 1300 and shift into 6th. For 25 MPH 2+5 is 7 so shift into 7th at 1300 rpm.
Why do you double clutch a semi?
Operating a manual transmission in a big rig isn’t like the stick shift you’re probably used to. For one thing, semi-trucks require that you double clutch when shifting gears. This means engaging the clutch to pull the gear out, letting the clutch out, and then engaging it again to shift into the desired gear.
Why do truckers extend their shifters?
A longer shifter column provided more leverage when having trouble getting the gears to mesh together. Today’s transmissions are much smoother and easier to shift.

How do you downshift a 10 speed?
If you’ve ever let the clutch out while turning and had the car lurch and have the rear-end (in a rear-wheel-drive car) begin to skid, then you know what I’m talking about. Think of the approach to any corner than requires slowing down as a brake zone. You want to do all of your downshifting during the brake zone.
