Most "eight" speeds are actually nine speed transmissions, designated as eight speeds to distinguish them. For example, the 8LL, which has a gear reduction range for off-road usage, is still a nine speed at it's core. See the related link for a visual pattern of a nine speed transmission.
I want to see the shift patterns
typical H pattern ....push down and to the left for reverse
changes the shift pattern on the transmission.
Allison doesn't make an 18 speed transmission.
The 2004 Harley-Davidson Fat Boy utilizes a standard gear shift pattern typical for most motorcycles, which is a 5-speed transmission. The pattern is one-down for first gear and four-up for the remaining gears, meaning you shift down to engage first gear and then shift up sequentially through the gears. To shift, the rider uses the left foot to operate the gear shift lever. Always remember to use the clutch when shifting to ensure smooth transitions between gears.
I have a 1987 Pontiac Fiero GT and the shift pattern is: 1 3 5 2 4 R
1 down 5 up
The 1979 Harley-Davidson XLH 1000 features a four-speed transmission with a standard shift pattern. The shift pattern is one down for first gear and three up for the higher gears, which means the rider shifts from first to second, third, and fourth by moving the shifter upward. Neutral is located between first and second gears. This configuration is typical for many Harley-Davidson models of that era.
No way to answer this without knowing what transmission you have in there.
You're not going to learn this by reading about it. Also, you need to specify WHICH twin stick transmission.. the Mack transmissions, for example, had a unique shift pattern uncommon to other transmissions.
Four speed transmission is : one down, three up.
there is no fuse that makes the transmission shift the transmission shifts on cylinoids and rpms
