What RPM should I shift 10 speed?
Look at your speed gage and it will almost always tell you your gear. 25 (2+5=7) shift on the tens (10, 20, 30ect) low side shift between 1000 and 1200 rpms, highside shift between 1500 and 1700 rpms. Downshift at 1000 to 1200 and rev to 1400.
At what RPM should you downshift in a semi truck?
Do not attempt a downshift until the engine RPM has slowed to or below 1100 RPM while in gear. This gives the engine room to raise one gear step in RPM to successfully perform the downshift. When the RPM begins to work its way towards the bottom end of the operating range, under full throttle, it must be downshifted.
What rpm do you shift a semi at?
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.

Can you shift a 10 speed to 13 speed?
You can actually drive it much like you do a regular ten speed. The major difference is that there is a second splitter on the thumb side of your shifter that will allow you to split those higher gears if needed so that there is not such a momentum grabbing gap in the way the RPMs drop off in between gears.
