without clutch came about since Jericos or G-forces,or anyother face plate trans,people shifted old crashboxes(synchronizers took out every other dog took off gear)and pro
shifted gears without the clutch,just can't do it many times. face plates made it to where
you can do it for 100's of passes.
Anybody that is good in a stick car will tell you shifting is the easy part with or without
clutch or clutchless doesn't matter.
The only ''helpers'' I like and use are high side rev limiter and line loc switch released
with clutch and can do without if want to.
People that worry about losing to sticks are the same ones that would worry about
a quadrapalegic having a advantage in a fist fight.
I would be ashamed to have a RPM activated shifter to make one gear change.

Very well said

i am not knocking anyone, but take the rule out or enforce it (must be shifted in a conventional manner) is what i am saying. and i have drove both and for me a true clutchless is way smoother than conventional. the car calms down tremendously when you are not unloading the chassis. the way most people are shifting manuals they just as well allow true clutchless, it would be less expensive in the long run. after testing one i think i could learn to like that.

I was told there is no advantage of running a true "clutchless" trans compared to clutch (i.e. GForce GF-4R or Jerico DR4). The primary advantages with the DR4 over a T-5 is durability and quicker shift action. I learned to "speedshift" a stick long before switching to a Jerico. And while you can shift the DR4 without kicking the clutch, it's usually at the expense of "out of power band" shift points or a fully adjustable clutch like Soft-loc or Advanced is used.

I have a friend who purchased an ex Larry Morgan Stratus complete with power train (Liberty) which turned out to be a nightmare. He found that clutch setup was very critical..and difficult to master. It made the difference between tire shake or destroying clutch discs @ $400 per set. Tire shake ended up equating to chipped gears @ $500 per repair. Shift points also played a part in keeping it in one piece. The first 2 outings costed $1200 with only 5 passes. So the Liberty went bye-bye in favor of an automatic.

Lenco is perhaps the easiest to operate...but it's a power robber especially with lower HP engines, requires many adjustments, and stupid expensive.

In the end clutchless transmissions (might) offer a couple hundredths, but at a ridiculous cost.

i think every combination differs. i have personally not seen anyone break a g-force cluthless at are local track, and they all picked up when changing from a trans that is clutched between gears and a true clutchless. we only know what it did for us. not changing any thing in the clutch from one set-up to the other we picked up .09 on second pass, and according to the computer we missed the shift points by a few hundred rpm. we just ran a single disk soft lok.

Re: Clutchless tranny in S/S?
 
I agree with you Randy. Gary I wouldn't use anything but Mc Leod or Advanced or same as.If you run anything other than sintered iron disc and adjustable pressure style pressure plate you'll most likely regret it. Years ago Red Roberts that used own McLeod convinced me to try his setup and that was best decision I ever made,what sold me on it was he asked if I ever noticed a time when my reaction times were more consistent ,I said sure the last two-three weeks before my disc wears out I would kill tree all night (without going
red), Red said that's what I'm talking about see what happens when you lower pressure. Soft Loc style setup cost to start with but are well worth the price they'll run longer than any other style setup without destroying driveline.
Gary your buddy's pro stock deal that's a whole different deal when you get in those type cars you better know what you're up against there is a hardly no room for error.I've got alot of clutch experience I could probaly get it figured out but I'm sure I would junk a pile of parts in the process.Pro Stock-Comp style clutch is high maintance &high skill level.
What Iv'e seen is clutch trans shifted without clutch .07-.08 quicker and just estimating clutchless trans would probaly be worth about another .05 or so.only difference is clutchless in always pulling where clutch type is in neutral split second on gear changes if cars violent on gear changes using clutch not using clutch is going help more because
car will make smoother pass.

If Ronnie Sox and Herb McCandless could shift the way they did in the '70's with virtually stock 883's and a clutch why change?

Practice, practice, practice!

better inform warren johnson, ken blacks bunch, and jegs. they are spending alot of money on nothing when purchasing high priced cutchless units when an m-22 muncie is just as quick. would save them a ton of money. if clutching the car was as quick, everyone not clutching would start doing it to save on break downs. i know it is harder on parts to pull a clutch assisted trans in and out than it is a true clutchless.
