I punched the odometer reset button and it went back to zero for trip miles. Then I noticed that the odometer is not registering mileage any more. The speedometer works fine; the mileage just does not change. So I am stuck on 259,000+ total miles and 0 trip miles.

Guessing that some gear has broken but I have not taken it out of the dash yet. Does anyone have a recommendation about what gear I should order - or what?

Thanks.
