Hey Rob, How are you sir?
My gut feeling is that PCS 1-5 Cmd is the Pressure Control Solenoid (Clutch Pressure Trim) commanded state. We are after the Transmission Fluid Pressure Switch state (TFP Switch 3 Hi/Low or Open/Closed) Hi/Open meaning the 1-2-3-4 clutch has pressure. Do not confuse Internal Mode Switch (IMS) states with TPF switches.
For someone that has been reading data on a Tech 2 for the last 18 years.....Reading HPTuners data is like reading a different language, Their acronyms for some things are baffling to me or just flat wrong....For example on some 4L80E data that I recently went through on the HPT scanner the 1-2 shift solenoid (A) is labeled 1-2 shift solenoid which is correct, The 2-3 shift solenoid (B) is labeled 3-4 shift solenoid, Alas.....It also had no data for the TFP switches.
