See related link at the bottom. It's essentially a nine speed, with the option to split the gears on the high side. It's good to have for those times when you're "stuck between gears" - for example, you're pulling a hill, and the gear you're in is a bit low, but if you shift a full gear up, it'll bog down.
No such thing. Are you asking about a Super Ten transmission, or a 13 speed transmission?
No you cannot change a 13 to a 18 speed, however you can change a 18 speed to a 13 speed just by changing the shift knob.
Keep rpm between 1400 to 1600
shift it foward
It's a nine speed transmission, so see the related link for a diagram. The diagram is actually of a 13 speed transmission - the difference with the nine speed is that it doesn't have the High/Low settings for the top side. The nine speed "H" pattern is the same basic pattern used for the 8LL, 13, and 18 speed transmissions.
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.
Allison doesn't make an 18 speed transmission.
I want to see the shift patterns
No you can not, it is a different transmission. The 18 speed has a splitter for the lower range as well as high range.
yes
how do you put gear shift back into 1993 ford f-150 5 speed transmission
It shifts itself.
