ODOMETER STOPED WORKING.

Check the trans fluid level first with the engine running. If its low , top it up. Then go back and have them take care of the valve issue.

More than likely it's the filter clogging up with what used to be the clutches in the trans. Even if the filter is replaced you WILL have problems in the not too distant future. If you lived near me I'd say bring it by, don't run it into the ground it's cheaper and easier to rebuild it while it's still semi working than if you waited till it stops moving all together! Good luck

Replace the speed sensor on the transmission/transaxle,

cause the little plastic wheel the drives the odmeter is slipping on the shaft in the speedo head

Most definetly yes. It should run you around 500 dollars. If you timing belt breaks it will destroy your valves and head.

You may have a bad wheel speed sensor. only with a scan tool that shows data will you be able to determine if its a sensor issue or computer or gauge issue

Unfortunately, there is no fix for your current odometer. Your car will continue to rack up miles, but there is no way to tell (sometimes you can with a digital odometer). What I can suggest is getting a new.used gauge cluster and track your mileage from there.

*Note..sometimes the pin (s) used on these can go and cause this issue..it can be repairable if you have the time, patience and money...on the downside, if you've driven the car since it broke, no way on getting those miles added on...the upside..a cheaper alternative is replacement (check ebay or car-part.com)

yes the speed sensor controls the speedometer and odometer and they are electrical no more drive cable installed

You need to replace the VSS or vehicle speed sensor. Located on LH, lefthand rear of transmission.

The teeth on the ODO gear are most likely stripped. Seen this a hundred times. Dealer- only repair unless you buy a used speedo head.
