I just bought this car and noticed that it shifts into overdrive way to soon and randomly down shifts. Could this be a fluid level problem or is it a sensor. Maybe electronic shift?Help please!

Hi rshober173,

Thank you for the donation.

The transmission shifting is controlled by the PCM which receives signals from various sensors.

Is the Malfunction Indicator Lamp ( MIL) showing?
Did you check the fluid level and condition?
