CLUTCHLESS TRANSMISSION

The GF-5R clutchless transmission utilizes split, spring-loaded sliders. The engagement lugs on each half are ramped on the deceleration side. When the shift lever is pulled into first gear, both slider halves move to engage the first gear faceplate. When the shift lever is moved to the second gear position, only the slider half-facing second gear moves to engage that gear. At this time, both gears are engaged momentarily, but second gear causes the main shaft to increase its rotational speed. This speed difference kicks the first gear side of the slider out of engagement, (hence the need for the ramped engagement lugs). Subsequent gear changes operate the same way. All shifts are made at full throttlee, without the use of the clutch, just as they are with a planetary transmission. The GF-2000 clutchless transmission operates with a slightly different design than that of the GF-5R. The GF-2000 utilizes a different shift fork for every gear, unlike the GF-5R, which uses only 3 shift forks. Because of this, the GF-2000's return springs can be located directly on the shift rails, whereas the GF-5R has split, spring loaded sliders. Again, all shifts can be made at full throttle without using the clutch. Both methods work fine, but the GF-2000's design of having bigger coil springs directly on the shift rails tends to be better for a first-time clutchless driver. For more experience drivers, it doesn't really matter. Because of the unique engagement system of a clutchless G-Force, the transmission is not suitable for the street and will pop out of gear under deceleration. Since the clutchless G-Force is not a planetary transmission, it doesn't impose the same type of power losses.
