Sorry...it was an old link....I guess it doesn't work anymore. The description in my post was copied directly from that link on Subaru Review.

Here are some pictures of the system:

Here is another little write up I found online for the system:

5Zigen releases the Twin Mode Clutch System aftermarket transmission upgrade that offers the best of both transmission worlds: manual & automatic! Such an interchangeability option in a vehicle is a luxury only offered on production models like Porsche's acclaimed Tiptronic, Alfa Romeo's superb Selespeed, and Mitsubishi's innovative INVECS II. This upgrade option provides a driver an automatic transmission mode while driving in heavy downtown traffic or in a traffic jam. It also allows the driver to switch to a manual transmission mode when driving in suburban town areas or when the driver is attacking the slopes & bends on challenging mountain & canyon roads.
The above is achieved by having an on/off switch on the shift knob. Depressing the switch turns the system on, and the transmission will act like a clutch-less shifter, where each push of the gear knob will raises a gear, and each pull of the gear knob will knock down a gear.
The switch on the gear knob is to activate an actuator connected to the transmission oil pressure line. Actuation is controlled by a motor which mechanically disengage the clutch. Such an action will convert the manual transmission state into a semi-automatic transmission state. The amount of adjustability for clutch cut-off is allowed by the actuating mechanism during the twin mode system's set-up.
The Twin Mode Clutch System comes with a computer-controlled pump that controls the clutch's oil pressure, and cables that are used to actuate the switching system. Control in semi-clutch state is made possible by activating the switch on the gear knob and letting the computer to control the actuation.
As a result, interchangeability between M/T & A/T is made possible by turning on the switch. Gear changes are made by turning of the switch. M/T & A/T are two different transmission systems but with the installation from this kit's computer controlled oil pressure pump to on & off the clutch system, the Twin Mode Clutch System becomes a reality. The computer works by reading driving parameters like vehicle speed, engine RPM, and accelerator, clutch, and brake pedals actuation.
