As you can see I am new to the forum.
My daughter just called me today and said that the overdrive light came on while she was driving and it seemed to bog down. She pulled over and cut it off and after the light came on again and was BLINKING. She made it home .We have no owners manual.

I need reliable advice before any further action.

By the way she lives 500 miles away and no family in the area.

Thanks for anyones help in advance.
