Friday I changed my Transmission Fluid, Filter, gasket ect.. and Saturday My service engine light came on. I used my scan tool and code PO753 came up - Shift celonoid A circuit- 1 of 2, does anyone know where to find these sensors and is it an easy fix, Truck is shifting fine and old fluid looked great, no flakes or crap in the pan..
