ok its the truck in my sig and i am getting this code i found out that its the gov pressure above 3 psi in gear with 0 mph so the question i have is what has caused this and what do i need to do to fix it i also get a lot of shuttle shifting so please help cuz i am on a tight budget

 

easy fix! Drop the pan and replace the pressure gov! good excuse to change the fluid!

 

Little more to it than that.

Sensor itself is $100, plus $20 for a new filter, and about $30 for 6 qts of fluid.
