Fault trans, blinking o/d off light?

Hello, there's a fault within the electrical components of the automatic transmission, which could be an internal issue, an external sensor or component issue or some kind of wiring issue. Hands on testing will be needed, aided by the use of a diagnostic tool capable of monitoring and troubleshooting components. Hello, why the replacement alternator in the first place? What testing was performed then? This is not something I ever see, and I do see Honda's daily for the last 13 years. As a result I'd be looking at wiring or modifications or non Honda components first to see what's going on. I don't see the CVT being an issue off the top, because it won't affect hesitation unless the engine is revving up without moving the vehicle. You may also be extra sensitive to the vehicle with all that has happened; dealers have the luxury of comparing to a like vehicle, so perhaps they could do that and give feedback?
