2007 Kia Spectra Q&A
2007 Kia Spectra Question: Flush or fluid add?
would flush first then change filter and gasket and refill - Tomiko
Unless dealer will guarantee the trans will be fine after 'flushing' , I would recommend a simple drain and fill , with a filter change , if that applies to that vehicle. Would also recommend ONLY using KIA ATF. - ziptie12
