Do you happen to know what range the dummy gauges scan from? like oil PSI 0-100 and is it linear? Also what about the tranny temp gauge. The 2010's you can't actually see the temp just the gauge with no numbers. Thanks
Oil pressure gauge will drop out below 7psi oil pressure. The trans will show hot around 268 degrees I believe a transmission overtemp code will set at 275 degrees and go into limp mode. diesel shows overtemp at 258 degrees on oil temperature. The 268 on trans temp I think is about where is starts to show overheating but not 100% positive. Optimal trans temp is 175degrees. every 10 degrees over that they claim shortens the trans fluid life in half. The 6R80 trans is susposed to be filled for life and never need flushing according to Ford. Pulling my 4000lb boat over a pass I've seen my trans temp get to 230 degrees and that made me nervous. I'm still researching with the synthetic trans temp is different then older conventional. If I ever figure out the answer I'll be sure to post it.
