Hi i have a question i have a 2017 F150 3.5 V6 Ti VCT 6 speed I've been noticing that on just a normal drive not towing just me and iam only 170 lbs but my transmission temp gets to 203 or 204 is this normal?

The transmission is thermostat controlled to ~195*F. You are well within the normal range, but I'm surprised to see it over 200 with no load. Does is stay at that temp, or Maybe it's due to a lack of (or smaller) cooler than the tow package trucks, not sure. but my '12 EB almost always runs right around 195 once warmed up, and if towing (usually 5-6K lbs) it will fluctuate from high 190s to about 205.

Does your go up to 203-204 then back down, or does it stay there?

it stay at 203, 204 and yeah i dont have the small cooler but iam installing an after market one.

Mine stays in the low 200s while not towing. Seems normal to me.

I have the 2016 version of your truck. Based on looking at a service manual on the 6R80 transmission a few years back the normal operating temperature for your transmission is 193ºF - 215ºF. I had to know this for checking the fluid level which I recommend doing as mine was low from the factory. Your operating temperatures are perfectly normal.

Mine moves between 195 and 204 per the dash. It's normal to have an operating range for engines and transmissions. Both have an incredible range of heat generation, and also fluid flow rate which is dependent upon engine rpm.

I see low 200's when I'm driving lower speeds with intermittent small towns (2-3 intersections). Makes sense, heavy heat generation (accelerating), while not getting up to speed to pull max heat out of the system. Luckily, the bigger the thermal difference, the more efficient the transfer.
