2019 Transmission Temps

Curious what other are seeing for Trans Temps. My truck is 2019 CC F350 Dually 6.7 with 4:10 rear axle.

Running empty I see 205 to 207 temps however when idling i see 196 to 198.

This is my third Super Duty and my 2013 Dually ran a little less.

Thanks

I guess I'm going to assume that with the diesel the trans runs hotter. My 2019 f250/cc/sb/4x4 with the 6.2 towing my 13.5k FW, it maxed at 197 going up hills. Cruising it was at 190ish. Not towing it peaks around 160ish?

There is a thermostat in the trans that keeps the fluid up to temp for efficiencies. It's totally normal.

I believe those are normal operating temps for a 6R140 transmission.

Mine is usually between 194-198, F250 6.7L.

I have a photo of the gauges about 2 hours into an all highway trip, shortly after completing a regen, and the trans temp says 196.

Our 2019 F350 is equipped with the 6.2 and 6R140. Once warmed up, which can take a while, the AT temp smoothly rises and falls between ~196 and 205 F as the transmission thermostat closes and opens.

HTH,
Jim / crewzer

The F-250 gas has a different trans than the F-250 Diesel and the F350 Gas/Diesel.

An important distinction.

Thanks,

This has been covered a lot. Searching will give you lots of other discussions. Temps are higher than many are used to seeing.

My 6R140 sits right at 194 when fully warmed up and no load. Same for the coolant temp. 194 F is apparently the set point. With stop and go traffic, it’s easily at 200 - 205. When towing, it’s in the 210 -220 range. When towing 7,000 lbs going up 7% grades at 10,000’, it can get as high as 230.

All of this is normal. Everything is about 20-30 degrees higher than conventional wisdom from the 1980s, e.g. Most online articles are written around this older expectation and will talk about 170-180 being normal, 215-220 being danger zone, and 230+ being in the “shut it down and let it cool off” zone. None of this is applicable anymore ... not to modern Fords, anyway.
