Message: [QUOTE="Charles, post: 1566464, member: 103"] No.... it is a stand-alone trans controller. You literally tell it which outputs go to which solenoids and what order you would like to fire them in. I run my EPC valve based on MAP for instance.... not TPS. My trans is nearly always spot on with shift firmness this way. You can do just about anything practical with a PCS. I used to independently run the gate on my GT55 and the gate on the 38R with PCS PWM outputs based on two independent pressure sensors, one for each stage, while also kicking on the water injection at XX boost and kicking on the second stage water nozzle at XXX boost, while holding a manual shift controller in my right hand on a short extension harness with manual/auto toggle and shift up/shift down buttons on the little handheld remote. On my crew cab another one is currently wired to kick on my second factory fuel pump if the main pump drops below 50psi... It has various digital and analog inputs and outputs and most certainly drives the trans solenoids, wastegate valves and relays directly. I have used them for years. The original. I have not used the newer unit. I still have two of the original units. [/QUOTE]
