Autos have wet clutches ; plates with linings on between steel plates in fluid
However these engage as one unit; the "extra "clutch can not be controlled seperately
I want 500+ ftlbs too.

some of these guys are talking lt1's so they might be able to
wind out quite a bit longer than us, but I have done like 90 in 2nd gear with a stock tpi going through curves with a 4+3 3.07 rear end tpi car chasing me, and I garuntee he was well into third:o
What gears do you have now? what is 2nd peak?

I think I am being called out so...
An automatic trans uses the direct clutch and an overrunning clutch to hold the planetary gear set when starting in drive. If you place the gear selector in low, it ALSO applies the Low/Reverse clutch giving the transmission a better grip on the planetary gear set and reducing the chance for a transmission failure. This is also the clutch that applies when downshift to first causing the car to slow more quickly, unlike when you are in drive and the car coasts when you take your foot off the gas pedal.
If you would like more information on automatic transmission operation, please feel free to stop by my house and I can give you lessons on operaton and rebuilding of automatics. I am an Automotive Technology teacher and an ASE certified Master Automobile Technician. Class dismissed, let's go get a beer.

Could you make me a DVD and mail it? I'd love to rebuild my own next time. j/jk
Here's the parts pics from my last trans rebuild if anyone is interested.
