P0748 Code/Sanity Check Okay. I have that level 3 transmission installed, and slapped on the new torque arm. The Trans upgrade included a Transgo HD2 and the Vacuume Mod with resistor.
I'm continously throwing a "P0748 Pressure Control Solenoid Circuit." I did hook the vacuume line between the brake booster and the back of the intake manifold. During this process I pinched it once pretty good, but I don't think there was a rupture in the tube.
My questions are:
Isn't the resistor supposed to stop that DTC from being thrown?
I believe the resistor is seated firmly but is there a way to tell without having to drain the fluid and drop the pan?
Could a rupture in the vacuume line cause this issue?
Could this code possibly be thrown due to a low ATF level?
