I had the "Turbo Speed Sensor" go out on my Optima 2.5 V6. Not sure if it's the same engine in your Sedona. Part was $100. Labor $162. Big rip off on the labor. I know know that this was only an eternal plug in solenoid. A
15 min job.Part was worth about $.50 of plastic
Car, all of a suden would downshift on its own and would no longer shift into 4th gear.
Thanks for your help, It is a v6 3.5 engine, I already spend $500 on a transmission shop that thoght that the problem was the computer, that, did not fix the problem. Now the electric shop is charging $500 just to try to find out what kind of problem this car have,
