Hi I'm Kevin it's highly likely that the brake lights being on all the time are the cause of the problem it's quite likely that the cause of the problem is the brake light switch as they are a common failure it is located on the top of brake pedal unit in car

What about the transmission not shifting?
Customer: replied 1 year ago.
Are you still there? I didn't get an answer about why the transmission doesn't shift.
Expert:  Kevin replied 1 year ago.

It's likely the brake light switch is causing this also as the transmission is going to get very confused if it thinks the brakes are on all the time

Expert:  Kevin replied 1 year ago.

With manual mode you are effectively overriding what it thinks is occurring
