Since you've stated that the torque converter doesn't multiply torque, would you share with us what function the stator serves.
I've attached a picture of the major components for reference.
Thanks in advance,

how bout you read this and then tell me it "multiplies"-
"The stator resides in the very center of the torque converter. Its job is to redirect the fluid returning from the turbine before it hits the pump again. This dramatically increases the efficiency of the torque converter.
The stator has a very aggressive blade design that almost completely reverses the direction of the fluid. A one-way clutch (inside the stator) connects the stator to a fixed shaft in the transmission (the direction that the clutch allows the stator to spin is noted in the figure above). Because of this arrangement, the stator cannot spin with the fluid -- it can spin only in the opposite direction, forcing the fluid to change direction as it hits the stator blades. "
What I think you want to say, instead of "multiply" is "transfers". The torque converter merely transfers the power from the engine to the transmission to the wheels.
And yes, most new toque converters have a lockup feature. I dont know the details of the Z's, I drive a manual as I have forever.

No flaming intended, but im sorry, it does not multiply torque. If it did, then just throw me on one that multiplies it by 10-20 and lets race. I might be misinterpreting your language, but to say it "multiplies torque" isnt right. If anything, torque converters reduce torque due to the internal drag.

No flaming taken or intended.
I agree with the first paragraph in the statement you quoted, above as far the explaination goes. However I have a few questions/issues regarding the information presented in the second paragraph... but that's for another time.
That said, I continue to repectfully disagree with your statement that torque converters don't multiply torque. Torque converters that don't multiply torque are called fluid couplers. M-Benz tried a fluid couplers years ago and ended up with a disaster.
Perhaps if I re-phrase my question -- What does the stator do during the initial launch of a modern AT equipped vechicle?
Still don't believe me? I suggest you talk to Andre at Edge Racing Converters. He a very interesting guy to talk with and since he currently holds several torque converter patients, I tend to listen and believe what he has to say.
Andre built a Street Edge Converter for my car that increased the stock torque multiplication from a 1.6 to somewhere in the 2.2 range. Does it work? Don't ask me. Ask some of the guys on this forum who also have one of Andre's performance converters.

Here's a complete explanation on each components of a TC and how torque multiplications occurs.

here's some more reading on TC's

Let's all get edumacated before we lecture each other.
