I'm told that a true clutchless trans is a better deal, but much more expensive.
So there ya go...More goodies for the entry level class LOL

I run G Force 5 speed transmissions in my 13 Cobra-Jet. When I run in Stock i use the 1 Piece Sliders that are considered Non Clutchless. In a street version they have a 7 degree back cut to hold them in gear. In most stockers we get them with a 0 back cut to allow them to be pulled out of gear under power. Even with that modification it's very difficult to make the 1-2 and 2-3 shifts. Most times I over run my intended shift point as it hits the limiter before it unloads the slider and allows to be shifted.

The "Clutchless" sliders are split into 2 halves with springs holding them together while in neutral. When a gear is engaged the shift fork pushes one half of the split slider to engage the lugs on the gear. When you make a shift the net gear over rides the RPM the previous gear and that half returns to center on the hub. The hub has 3 roll pins that keep the split halves from over riding the center of the hub.

To use Clutchless sliders in my transmission I change 2 sets of hubs and sliders. If one wants to purchase those parts I would guess it would cost about $1,000.00.

My clutchless transmission is worth between .05 and .07 over the clutch assisted transmission. Changing nothing but the sliders allows me to shift at optimum RPM.

I will sometimes use a Rev Limiter offset per gear to "unload" the sliders in stock. It's slow but seems to be more consistent.

When I have been torn down for a National Record they rock the car in several gears to verify that I don't have a clutchless transmission. The split sliders will pop out of gear if you rock the car.

The clutch I use is a billet twin disk. With the counter weight at RPM I would break the linkage before I could disengage it LOL.
