is 95 degrees on the trany temp for a 2018 f150 an issue? I also have a knocking noise intermittently while driving as well, is that related?

 

95 degrees is way low for the modern trucks. I THINK the normal temp for your model year is between 200-205 degrees F. I have no idea what your knocking noise could be, but I don't have it. I'd try to locate the cause. I wonder if your tranny temp sensor wiring is faulty?

If that's 95 C that's normal. That's 203 F.

 

I'm no expert, but let me try and put this into perspective for you in Celsius
52 is the lowest temp I've ever, on a vehicle built for towing a large trailer.
68 is where my 2008 F150 with towing package normally ran.
74 is where my 2008 F150 could run up hill on a hot summer day.
78 is where my 2008 F150 would peak out at pulling a dump trailer in the field on a hot summer day.
88 is my best recollection of a temp you don't want to see because the fluid starts to break down.

 

You can't go by 2008 with the old 4 speed, the new 10 speed is *designed* to run around 95 C. There's a thermostat in the cooler line to keep it there. It also uses ultra low viscosity fluid.

Wow, that's hot for a normal temp. I watched my temp every time I drove the 08, but have not seen the temp on my 19.

 

I just did some research. Ford says the normal ATF operating temp range for the 10R80 transmission is 206-215 F. That's 97 to 102 C. The yellow zone starts at 250F which is 121 C. Mercon ULV is good to 275F (135 C).

 

If were talking 95c that = 203 degrees.
Not at all a high temperature for transmissions.
I routinely see 145-150 running empty on a 4r70 and 185 on a 10 speed with no loading.
Depends on the outside temperature because the Pan does a lot of cooling.
Same with oil temperatures.
Pulling a load of GCW in the 6 to 9000 lbs range up a hill that is long would reach in the 240 range.
My note: these temps are measured right out of the transmission converter out put where it's highest, not in the Pan where it's cooler.
Don't worry too much until the temps gets above 260.
If done to often or on routine, change the fluid more often.
