I don't think they should be allowed in Stock or S/S and Lenco's definately NOT!! The excitement went out of Pro Stock the day they allowed Lenco's.

By cheaper I was referring to overall maint. costs. I am aware of the initial purchase price difference, but my point was geared more towards being more economical in the long run. Much easier on parts.

Okay, easier on what parts? I would think the driveline shock would be worse due to less clutch slippage. Maybe the clutch will last a bit longer but with the right setup for your combo and adjusted properly they don't wear out that quickly. Routine maintenace is required on any race car and more so as the power goes up. My Jerico manual says clutch slippage on gear changes is mandatory to prevent trans damage. I know guys with 400+ runs on a Jerico and wonder if a clutchless trans would last that long. Not arguing with you here, just trying to learn something.

I'm certainly not trying to argue with you either. It doesnt really matter how much we try to hash this out, it boils down to the fact that it probably will never be allowed. And should it be like anything there are plenty of pros/cons to deal with. But with all the money slung at these cars what the hell is the difference I suppose.

If you go to the parts for sale section I believe you will find more adds for Jerico wanted than for sale

Well Guys Ive Thought ALOT of Mods For years Have Changed The Whole STOCK/Super Stock Venues...I Myself Think That LenCos and Planetary Trans should be Disallowed....
As In My Cousin Bullet Bob Reeds Words"I Dont Know What These Kids Are Doin Without Having A Gear Shift To Change Gears With...Taking A Cruise On A Saturday Night".......

No LenCos!!
I Have Tried Them And They Are Actually A More PIA than anything Else AND they are WAY more Expensive...

I hate to break it to you, but the clutchless trans, not planetary lenco's, is a done deal for 2010. Stick shift racers need to voice their opinion or be prepared for one of two options, either be prepared to shell out six to eight thousand for the gearboxes or get left in the dust by those in your class that do.
Once again, why the change, what problem are they trying to fix?

Have you priced a "PRO TRANS" lately ! Thats an automatic for those of you who are out of the loop.

Tony, I feel your pain I've got a G-Force Clutch assisted on the shelf for my AX car.That's nearly $7000 for a trans. that may not be competitive anymore. And yes I've watched my Gmeter with both trans in the car, actually the accel rate would go higher with the clutch assisted mainly due to being in nuetral for a millisecond. The main difference is my clutchless went many- many runs with no issues, my clutch assisted required repair after 30-50 runs. I'm not advocating for or against the change as my current car has a "grannie" tranny. It's just always been an issue that what we have now is going to be obsolete next year, tricker-faster parts are always comoing down the pike. The question is do we spend the money? Like so many things in racing we rarely get a voice in the decision making, they make the rules and we try to race within them. Joe

I'd have to disagree about having the same clutch setup for both trans. I ran a much softer setup with the clutchless, alot less "hit" on the gear change than the clutch assisted. As for the trans, guys saying you must have clutch slip in the gear change that mostly is to cover their *****, less hit means less damage. I've been through it, the clutch guys say one thing so you don't burn up their clutches, then the trans, guys say exactly the opposite so you don't hurt the trans.Been there done that. I can only say from my stand point I used up $300 worth of fluid and clutches this year with a tweak over 100 runs. That same number of runs with my G-force would have used over $1200 worth. Buy a Faceplate and a slider a few times, it adds up. Now, Do I hang a cluch pedal in the stang? Joe

I've wondered about the "slip when you shift" mandate. If you zoom into the timeline, the shift is made and the shock load goes through the driveline. The additional load of the higher gear then pulls the engine down, reducing certrifugal clamping force on the clutch and it slips.
By the time the clutch slips any damage has already been done. Just a thought.
