The first step is to measure the resistance of the coils in the new solenoid, just because it's a new part doesn't mean it cannot be bad, see that a lot these days. If both coils read the same or very close in resistance, then you move to the PCM, which is behind the right kick panel in the interior of the car. There you follow the testing process in the earlier post. You are looking there to see if the resistance is the same at the PCM connection as it was at the solenoids. If it isn't then you know that there is a problem in the wiring. The test process would show you if the wire is broken, shorted to ground or shorted to power. The code is a circuit code, so it is electrical and not related to the fluid or anything else in the transmission. To do the tests you need a multimeter.

Then just follow the test procedure. If it shows a broken wire, follow the wiring harness from the solenoid looking for damage. If you find it, repair it and clear the code. This is a continuous code so if it returns, you still have an issue.
