@Kintosol89 Hi, ok the Press. Cont. Sol. circuit low means gone to ground. You may not have a solenoid fault. This is how it works: A relay provides power feed. The ECM grounds the solenoid. If no power is seen at the other side of the relay, then you get a "Circuit Low" code. You need to pull out wiring diagram. Alldata information systems have DIY accounts for one car, one model only. Check it out. Probe and make sure you have power feed to the solenoids. Post back with more...

[ADPTraining]

You can gain a lot of insight on the problem by referring to the OBD-2 code. These are either Circuit-Fault, or Mechanical in nature, also circuit low or high. Look up the exact definition for the code. Good luck.

Can a faulty safety neutral switch affect the way a 4l60e transmission works? I was told that it could.However,I thought this switch only prevented the vehicle from starting in gear,and made the indicator light work on the dash to show gear position.Does it do something more?

[ADPTraining]

@SunsetNap YES it can. The NSF tell the TCM which gear it should be on. There's a varying voltage that goes to the TCM (Trans Computer). It's not a simple on and off switch indicating Neutral and Park. On most systems the TCM then broadcasts the gear position via the vehicle network for the dash to show the shifter position.

@jpr there are a few things that cause. Miss adjusted throttle valve broke or stuck accumulator stuck valve in valve body broke or missing anti clunk spring

Want more. I say find the maker and seek what more there might be available, Dont hesitate if you want to learn automotive electronics, Diagnostics This Many Conception has much to offer . Start by looking at this site. autodiagnosticsandpublishing I seen much of what I needed for many years, But didn't know about it's availabiity. Dont forget american made from what I understand, Dont missout on what you need and your american country needs.
