Has anyone tested the signal from the throttle position sensor?

I wonder if it is erratic when you change throttle position, hence the gear changing, but no errors because as far as it knows it is reacting normally to the throttle position information received?

Do you have access to diagnostics and live data?

Hello and welcome to JustAnswer!

As mentioned, an inaccurate throttle position signal would be a likely cause for what you're describing if no codes are setting.

Do you still need help?
