Transmission warms before radiator

[honemch]

I have an 09 F250 6.4L... Just noticed the transmission fluid temperature gauge heats up to normal operating temperature well before the radiator fluid... According to the gauges anyway. I would think the radiator fluid would heat first with the truck just idling. Is this normal?

My transmission also heats up before the coolant. I always assumued it's normal.

The gauge reading for the trans reads differently. I'll have to find the pic on the temps at what position again.

There is alot more coolant than trans fluid so yeah it makes sense.

Valid question. Mine does it too. Has always done it. Not sure if you noticed that you posted in the 6.4 section though.

If you are reading this from the factory temp gauge in the dash - its an idiot light at best.

(I have a 6.0L, but the same transmission) My dash gauge will show the transmission at temp within 10 min on a cold day, where the analog gauge will show maybe 110-120* when my coolant sits around 190*.

Check the numbers with an analog gauge or monitor.

I didn't know that. The app doesn't show the section. My bad.

I can't stand the app just use safari on your I phone it's way better. That gauge is pointless like somone said mine does the same thing at 110 it shows its fully warmed up and 110 for coolant it's still by the c
