does this have a oil change reminder ?

no it does not. I DOES, however, provide instant real-time activities with the car, like fuel rail pressure and oil temperature.

Does it record the mileage?

Yes, KW206 OBD2 gauge can display up to hundreds of engine live data including the total mileage.

Does this unit show the transmission temperature for a 2003 Dodge diesel yet? This parameter is hard to find on obd2 devices.

Sorry, the transmission temperature is not supported yet.

Sorry if that questions was asked but does it show your fuel gauge ? thank you

KW206 can show the trip fuel and total fuel.
