Transmission Temps and a better cooler.

My 2001 never sees anything close to that. I have a manual guage. They must have done something different in the newer models. If I we're you I would install a gauge to be sure because it's mechanical
Which I would trust more.

If it's in the pan, it's more an average temp than peak. Peak is what's most important. I think the factory sensor is internal to the trans, so it likely always reads higher.

As for accuracy, we're talking about either eyeballing an analog gauge or whole numbers for a digi-gauge. It's accurate enough, and the 270* sweep e-gauges are pretty damned accurate (like 0.1% or less error). Not enough to matter, especially when you're mainly looking for out of the ordinary temps.

Scan Gauge will display Ford trans fluid temperature through the "X" gauge function. Go to their website or better yet just give them call. Different years/models will require different codes but they are easy to enter at set up.

If you don't know your trans fluid temp then just keep it in Tow Haul on anything but a flat or mild downhill grade. Even a slight grade, 2 - 3%, can elevate your trans fluid temps after just a couple of miles.

:C

I run mine in tow/haul 100% of the time. It's hauling a house 100% of the time it's driving. :B
