Automatics have a "clutch" too they are just automatic and operated by hydraulic pressure...

Clutches and Bands in an Automatic Transmission
In the last section, we discussed how each of the gear ratios is created by the transmission. For instance, when we discussed overdrive, we said:

In this transmission, when overdrive is engaged, a shaft that is attached to the housing of the torque converter (which is bolted to the flywheel of the engine) is connected by clutch to the planet carrier. The small sun gear freewheels, and the larger sun gear is held by the overdrive band. Nothing is connected to the turbine; the only input comes from the converter housing.

To get the transmission into overdrive, lots of things have to be connected and disconnected by clutches and bands. The planet carrier gets connected to the torque converter housing by a clutch. The small sun gets disconnected from the turbine by a clutch so that it can freewheel. The big sun gear is held to the housing by a band so that it could not rotate. Each gear shift triggers a series of events like these, with different clutches and bands engaging and disengaging. Let's take a look at a band.

Bands
In this transmission there are two bands. The bands in a transmission are, literally, steel bands that wrap around sections of the gear train and connect to the housing. They are actuated by hydraulic cylinders inside the case of the transmission.

One of the bands




In the figure above, you can see one of the bands in the housing of the transmission. The gear train is removed. The metal rod is connected to the piston, which actuates the band.

The pistons that actuate the bands are visible here.

Above you can see the two pistons that actuate the bands. Hydraulic pressure, routed into the cylinder by a set of valves, causes the pistons to push on the bands, locking that part of the gear train to the housing.

The clutches in the transmission are a little more complex. In this transmission there are four clutches. Each clutch is actuated by pressurized hydraulic fluid that enters a piston inside the clutch. Springs make sure that the clutch releases when the pressure is reduced. Below you can see the piston and the clutch drum. Notice the rubber seal on the piston -- this is one of the components that is replaced when your transmission gets rebuilt.

The next figure shows the alternating layers of clutch friction material and steel plates. The friction material is splined on the inside, where it locks to one of the gears. The steel plate is splined on the outside, where it locks to the clutch housing. These clutch plates are also replaced when the transmission is rebuilt.

The clutch plates

The pressure for the clutches is fed through passageways in the shafts. The hydraulic system controls which clutches and bands are energized at any given moment.

The clutches contained inside an automatic trans would never produce smoke of any kind when they are burning up, the only thing that would smoke like that on an automatic is if an oil cooler line disconected and oil flew on to the exhaust.

Thats weird all those mechanics walking around scratching their heads, I think I was around 14 years old the first time I smelled a burning clutch.

It's a very distinguishable odor.

Dumb as hell. Especially the dude walking in front of the car. He would have been hating life had the car jumped and knocked him on his ass.

Looked like he forgot to disengage the traction control...the tires first spun just a bit and then stopped....they stayed stopped with the clutch fully engaged.I can't imagine how bad that must have smelled as the clutch was fried.

To the guy suggestiing its an automatic, the Z06 is only available in a 6 Speed manual.

[BaylorCamaro]

and yes they have traction control that you can toggle off and on.

Try scrolling through some of the other "Burnouts gone Bad" .... They are funny as all get out .... Check out the mom on the dirt bike .....LOL.....

OMG, HAHAHAHAHA. It was funny enough when she took off without doing a burnout, but then when I realized what she had hit...hahahahahaha...wow.

Obviously you have never seen somomne burn up an auto transmission,, yes they will smoke..., I didn't say this one was an automatic though, I was just saying automatics have clutches also...

Why does that Corvette look...smaller?

Yes, autos have clutches but they arent the same as in a manual. The driver really has no input into them and really cant hold them halfway engaged like this douche did. Anyways, someone has to be the "technical" guy and prove that so and so really has this and that.

OP, usually you will only see a manual toast the clutch because of how the driver never disengages it. This example, the driver probably left his left foot on the clutch while having it on the brake as well. When you do a burnout, you sort of side step off the clutch fast. This causes it to slip a little bit and then you put your left foot on the brake and this causes the car to not move. Give it some gas and you have a smoke show.



Watch the end of the video and you can see that the driver has the brakes activated and he is properly roasting the tires!!

This is a proper vette burnout..By Vette Plant manager Will Coskey...yes he meant to destroy it...if yo been to the show you would understand.

cause you drive a massive camaro
i was surprised to see how small they are in real life myself

Again in this case I said burn up an auto transmission, I never said anything about the clutches burning up.. you can hold the brake and stomp the gas on an auto transmission and it will overheat and the smoke will fly.. not as fast as this guy did on the Vette.. It is obviously not an Automatic.. as soon as he starts trying his burnout the smoke flies.. it would take longer to do that in an automatic, then once it does the whole transmission is toast...All I was trying to say is yes you can smoke an auto transmission..
