I had a trouble code for the oil pressure sensor that control the shifting on the transmission. I bought two off of Amazon for $50 and that was a mistake. I installed a new one in the bottom front of the trans near the radiator it last less than a month. I went and spent $150 at the dealer and it completely fixed the issue and made the shifting silky smooth. Lesson learned use dealer sensors. Apparently there is an identical second senor but darned if I can find a reference anywhere online as to its location nor is it visible. Is it under the airbox?
