Not financially possible to upgrade a FDI with FDII, you have to have a new transmission, and programming, and a lot of other stuff. You would easily spend 5-9k just to get the job done, you're better off finding a FDII patriot/compass and selling your current vehicle.

thank you so much for your replying, so you mean I need the transmission the programming? Can I find that in dealer's place or some other auto parts shop?
I do love my old FDI compass though...

The final drive gears are different too. Aren't those outside of the transmission?

The CVT2 and CVT2L have the same ratio range, but the cars gearing is where the 19:1 comes from.

you're right, it is the final drive, which is part of the transaxle, which is axle, transmission and final drive all in one unit. I guess you could swap one out, but that would be pretty labor intensive. The hard part would be the software, IIRC, the software is linked to the vin of the vehicle, you would have to tell the computer that it has the vin of a FDII patriot, and then let it load up the software for both the main computer, and the controller for the transmission. I don't know of too many dealers that would do that...

Not impossible,though for the $$$ not worth it.No dealer will do the programming so it would all have to be custom programmed,not cheap.It's not like 30 years ago when vehicles did not have any computers,today everything is computer controlled which ups the cost by almost what a new vehicle would cost to try and retrofit into another vehicle without it.

You can do anything if you have enough cash. But you would be better off selling your fdi and finding a fdii.
