5 Zigen Twin Mode Clutch 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. The ROM chip in the computer differs according to vehicle model.

For vehicles with twin & triple plate clutch systems, optional items (JPY 20,000) are required. Please enquire when placing orders.


And they make them for MKIV Supras! :D:D:D

That sounds great. A real sequential shifter instead of the limited mechanical operation offered by the stillway. Looks like quite a bit of work to install. I wonder if anybody in the US has it on their car. I'd like to hear some feedback.

Why do I doubt this thing works even NEARLY as well as it sounds.

"This upgrade option provides a driver an automatic transmission mode while driving in heavy downtown traffic or in a traffic jam" Doesn't sound too encouraging that the sequential mode is useful for driving in stop and go traffic, with no mention of racing except when you switch back to manual mode.

it's not a sequential shifter.
when you press the button, it activates it's own hydraulic system which in turn releases the clutch. you press the button when you want the clutch depressed.

basically the button takes the place of your foot.

i'm not sure what the computer gizmo is about.... maybe it'll depress the clutch when you let off the accelerator?
