is transmission changeover from cvt to six speed possible.

sorry but no.

The way I understand it I'm getting ready to swap to 6 speed the computer will allow it it will work perfectly fine but you will have a traction control tight on because 6 speed has a different Vin stored inside you need to change flywheel transmission mounts and cut one wire off the plug to the transmission trust many people did it plus new passenger cv axle
