Saw an old friend yesterday. She just bought a new 26 Toyota Crown Hybrid. They soaked her for..........get ready for it.....Sixty Six Thousand dollars. She had been shopping cars and admitted that she was worn out at the dealership and just signed on. That is $9,500. over what is...
I did one maybe two drain and refills with Castrol CVT fluid. Surely I extended its life.
And I am no longer anti CVT as the newer products work very well.
Daughter had 130K miles before her Rogue CVT failed. But in all fairness it was one of those problem years. So she did well. Got a rebuild and approaching 180K
I would do a hard re-set attempt. Disconnect the battery for a while and then re-connect and see what happens. Unless you know that is a no no for your vette.
