The Timing belt should be done at around 80,000 miles. It should be listed in your owners manual. Also, the transmission fluid I recommend being done at 30,000 miles. This is a great thing to do to extend the life of your transmission greatly!

This question arises time and time again.You need to try and find out when it was changed if ever was, If not work out the mileage.It is cheaper to change a belt than pay for a wrecked motor.An inspection of the belt may show some light to this question.The same applies to your transmisson question.As it depends what conditions your vehicle has been used.Obviously oil looses its vescosity the more work it does.
