Anyone know the max pressure of the transmission coolant lines under normal operation for the 4T65-E? The video below states that max normal transmission line pressure is from 223-271 psi, and can reach 275 or more with a bad PCS. Hayden trans coolers are rated and tested for 150 psi. I know the video creator is using a scan tool to set the PCS amperage to get those pressures, but doesn't that make it risky to install a low pressure trans cooler if those kinds of pressures are possible from a malfunctioning PCS?
