i have this code from my "check engine soon" light problem. P0797im guessing is something about a transmission valve body,i will appreciate any help or suggestions regarding my car issues. TNX

I believe P0797 refers to the pressure control solenoid, in which case you may just need to replace the solenoid or related electronics.

I got a second opinon from a transmission shop and in their scanner it wrin up code P0726. They told me no reading is coming back from the (turbine speed sensor). In case of any of those two things being true, is there a possible way that i can do this repair my self? If yes! Where and how much am I looking to spend in parts. In what part of my car will I find this sensors? I appreciate your believe MinisterofDOOM
