Trans Temp fluctuating?
#11
OKay my bad, fluid.
Automatic transmission fluid (ATF) is the fluid used in vehicles with self shifting or automatic transmissions. It is typically colored red or green to distinguish it from motor oil and other fluids in the vehicle. On most vehicles its level is checked with a dipstick while the engine is running.
The fluid is a highly specialized oil optimized for the special requirements of a transmission, such as valve operation, brake band friction and the torque converter as well as gear lubrication.
ATF is also used as a hydraulic fluid in some power assisted steering systems, as a lubricant in some 4WD transfer cases, and in the manual transmissions of many modern front-wheel drive cars.

I do not know what is happening but I highly doubt the numbers are accurate.

This only started after I installed the extra cooler. I have the larger factory cooler with my towing package. The new cooler has dropped my temps 10-15 degrees while towing my trailer. I am concerned that something is wrong, now that I see the temp fluctuating so much. The sensor is supposed to be in the valve body, submerged in fluid.

I think it is a reporting problem, I have seen the same thing with my scangauge, not as big of a change but similar. You could bypass the second cooler and see. I do not think I would worry about it.
I know it is a little unsettling to see it jump around. Makes me suspect the accuracy of the gauge.
What are you seeing for temps when towing? I saw 185°f towing my camper this past weekend.

I left that one alone although it would be a good Idea in north where it gets really cold.
The the external transmission fluid cooler has easy access for making a cover to block part of it off for winter driving and with a scangauge I can keep an eye on the temps.

It depends on where the sensor is. It is possible that it is located in a common passage that a few cicuits use. When you are rolling, it could get fluid that has been through the converter already and when you are stopped it is getting fluid that hasn't been through the converter. 10F change isn't something I'd worry about, especially dropping temp. High temp is what I would worry about.
