What was the "Nissan car"?Sorry your wrong when it comes to these main components like transmissions or engines. Since there are outfits that rebuild them for the dealers or the factory dealer network in the US. So that means all the parts for them are available. 2 years ago when I redid my daughters CVT in her Nissan car, $5,000. CVT's were available. So dah the part was available.
I also found out the dealers didn't know about the external filter for them, what does that tell you?
