As I said above, the transmission is the same from the 2024 and the 2025. They fixed the problem with swarf left in them during the manufacturing process. Metal cuttings.
The only downside to a 2024 over a 2025 is a reduced resale value because it's a "year older."
Pay for a month and cancel. Carista is the only OBD app that has that function. There are a ton of other OBD readers that can read codes without a subscription.
