Hi koh,
The CVT is continuously variable transmission which is the automatic gearbox available on N/A CJ lancers. Unlike regular automatics, a CVT does not have actual gears (eg. 5 speed) and works in a different way. Instead of switching cogs, there is a band or chain which moves along a cone shaped rotating assembly. As the band moves to a position of different thickness, the drive ratio changes, which is how a CVT operates smoothly with no hesitation due to changing gear.
TC-SST is the Twin Clutch Sport Shift Transmission available on turbo CJ lancers. This uses a conventional manual gearbox operation (as opposed to a regular automatic that uses a Torque Converter), only there is a separate clutch for odd and even gears. In addition, the operation of the clutch is computer controlled so it can be driven like a normal automatic or using paddle shift.

Of course, none of this is pertinent to whether your gear boot will fit, but I hope explains the technical difference.
I doubt that the gear boot will fit, as the size and mounting will almost certainly be different. On my last car, I bought a new gear and handbrake boot from the eBay seller "topgaiters". It was only 20-something dollars shipped from the UK, and he will make it in leather, suede, whatever colour stitching you want. Looks like he only lists boots for the Evo, but if you contact him he might be able to make one for the CVT.
