Ask the Mechanic Where can I service a CVT transmission? I recently bought a Toyota Fielder but did not know that it uses Continuous Velocity Transmission (CVT). After driving, it felt seamless and I was concerned. I checked the trans/axel number K310 which is mostly used in second generation Fielders and found out that it is actually a CVT type. My concern is whether we have the local expertise and spare parts for this type of transmission. Richard Hello Richard, your concern about the maintainability or repair of CVT transmissions is valid because there is a recent surge of cars with CVT transmissions on the used car market, yet the user awareness about how to use a CVT, maintenance and repair seems to be limited.
