Do you use a tachometer and a speedometer to shift on a tractor trailer?

That's how you're taught - use the tach to determine when to shift, and the speedometer for recovery speed if you lose a gear. After a while, you get to the point where you know when to shift by the sound of the motor.

No such thing. Are you asking about a Super Ten transmission, or a 13 speed transmission?

How do you shift tractor trailer gears?
If you have a low speed such as an 8-10 it is a simple double clutch and shift. But, if you have 13-18 you will have a low and high range switch. 18 Speed is simple for me It is in low range shift 1-4 at 4 switch to high range. Shift 4-8. So, in reality you are not actually shifting 18 times.

Why wont transmission shift out of first on 96 dodge caravan and peedometer does not work?
The speed sensor sends a signal to the speedometer to show the correct speed and it sends a signal to the transmission telling when to shift. If the speed sensor is bad the speedometer will not work and the transmission will not shift correctly.

What is wrong when speedometer doesn't work and the transmission doesn't shift in a 2004 impala?
Replace your speedometer sensor. I just had mine replaced in my '04 Impala. The sensor tells the tranny when to shift. It's located right in front of the transmission.
Where are the speed sensors located on a 1999 Mercury Cougar?
This part sits on top of the transmission. Look just behind the intake manifold. It is not easy to get to. Suggest you get a transmission shop to handle the work...probably less than $200. If you are trying to do this to correct shift problems, suggest you on wrong trail...try a shift control unit, which is located near the speed sensor. Unless your tachometer and speedometer are acting up, look at the shift control unit. It does seem to go out after 100k.
