Kia Troubleshooting Questions? Ask a Mechanic
The transmission filter is not meant to be changed regularly. It is roughly a 8 hour job as you have to dropped the transmission and tear the transmission down in order to replace it. I dont recommend this if you have never rebuilt transmissions before as that is essentially what you will be doing in order to replace the filter.
It is cleaned by having a machine flush done on the transmission
2008 Kia Spectra L4-2.0L
Once the low pressure tire is reinflated to the recommended pressure and installed on the vehicle, the TPMS malfunction indicator and the low tire pressure telltale will be extinguished. If the low pressure and TPMS malfunction indicators are not extinguished after about 20 minutes of continuous driving, please visit an authorized Kia dealer.
As you can see, the TPMS on your Spectra automatically resets once you inflate tires to proper pressure. So if none of your tires are low, or were low and you inflated them, then the light should have gone out after 20 minutes worth of driving. If it has not gone out, there is a problem with one of the sensors inside the tire.
You need to check the tire inflation on each tire and set them to 32-35psi. Drive for 20 minutes and light will go off.
IF tires are already at correct inflation or light doesnt go off after driving for 20 minutes, then one of the sensors inside the tires mounted to the inside of the rim is faulty. A scan tool is used to test them. The one that is bad is then replaced. To replace one, the tire has to be dismounted from the rim.
So you need a scan tool and a tire machine to dismount the tire from the rim and then remount it. This is not a DIY repair
As I previously explained, the light is designed to shut off automatically, and if it does not, then there is a problem with one of the sensors. There is NO workaround to shut the light off. The problem has to be diagnosed and repaired
