Trans Fluid Question

[powerstroke_n]

Under normal driving conditions. How hot does the trans temp get. Just installed brand new ISSPRO gauges and I'm getting no reading. Everything has been double checked, sensor connection, gauge connection & voltage to the amplifier box all good. Only thing I've not checked yet is ohming the sensor itself. If anyone has ohmed the sensor what reading did you see when hot and cold. Thanks for any reply.

When i had my edge evo hooked up i ran about 110-115 i think. That was empty just cruising around. i have never ohm test a sensor though.

I was wondering what it ran. My gauge starts at 140. I hope it's good with no problems. I guess I won't know til I put a load behind it.

depending on the temps in your area, trans will get around 80-100deg warmer than ambient.

My Isspro trans gague starts at 100*F and the hottest I have seen it lately under no load, just empty driving is 135*. It's possible that your ATF isn't getting hotter than 140*, therefore the gauge shows no activity. My gauge moves just fine, but it also starts 40* cooler than yours.

Normal is 70-90 above ambient, but Ford doesn't consider there to be a problem until the temps reach 230 degrees. If you have sustained temps above 200 I recommend more cooling.
Back to your question, you bought the wrong gauge, yours will work, but it won't move until Spring. I always recommend the gauge that starts at 100 not 140.
Good Luck
