I bought a pulled, second-hand CVT from a 2019 Mirage with 19k miles on it (so says the VIN and the yard). Total cost with labor: $1,500.

So the "new" used CVT replacement blew an 0962 code this afternoon. Solenoid A low current. Internet says it could be anything from low fluid to being born a middle child.

Any thoughts? Any order of diagnosis?

Anything you could share would be a huge help, including last rites, if warranted.
