I forgot to mention my transmission temps now stay in the 190 's form 205 ish . So my Raptor is a 2010 , it looks like the way the fans are wired is the low speed relay ,fans are in series and run at half speed , it has a high speed relay that kicks in and puts the fans in in parallel to receive full power and amperage . I think my tremor is controlled with a module that varies output to control fan speed. I know when i start the Tremor fans kick on for 10 seconds then off so i think if is a self test looking for load. If you wire your fans with separate wiring you may get and error or something. I think the diagram below this is how the system works on my raptor except signal come from ECU vs. Temp switch.
