The shift pattern is a modified nine speed transmission, with the option to split the gears via the button on the side. To upshift with the splitter, you get up to the desired RPMs, push the splitter button forward, let off the accelerator for a second or two, then get back on the accelerator. If you did it right, you'll proceed as normal. If you get back on the accelerator too soon, the motor will tack up very high and very quickly once you get back on the accelerator, as you'll not have caught the gear yet. You do pretty much the same thing when downshifting.
As for the progressive shift motions, if you're familiar with unsynchronised transmissions, the pattern is basically that of a nine speed. If you don't know how to shift one, you need to learn - either have someone teach you, or attend a truck driving school.
Allison doesn't make an 18 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.
No you can not, it is a different transmission. The 18 speed has a splitter for the lower range as well as high range.
shift it foward
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.
I want to see the shift patterns
yes
how do you put gear shift back into 1993 ford f-150 5 speed transmission
It's the same as the shift pattern for the Eaton Fuller nine speed transmissions, albeit with additional gears on the low side. For the sake of not wanting to type out a long winded explanation, there is a related link posted - 'Eaton Fuller 18 speed shifting diagram'. Click on that link to see a visual representation of the shift pattern.
It shifts itself.
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.
what are you wanting to take the transmission out completely or what?
