Transmission Temperature

I did some reading using the search function but couldn't find exactly what I was looking for.
I noticed today while driving my transmission temperature got to 185 degrees. It was about 85 outside.

My question is...is 100 degrees over ambient acceptable? I was not driving hard and had no weight in the truck. Seemed like it might be a little high considering nothing was being towed.

So 100 degrees over ambient is too high? At what temperature could failure occur?

What should it be in an ideal scenario?
I'll look into the 6.0 cooler.

Your not crazy high, below 200 is fine, above that and the fluid starts to break down fast and the trans can be damaged. Im live in FL, unloaded even in the hot summer months with the 31 row 6.0 trans cooler I rarely see over 150.

100* over ambient is okay/normal, but most people see that when they are towing something. You do not really want to go over 220* at all.

I would invest in a bigger cooler as well.

A 6R140 is a totally different animal than a 4R100. IIRC the 140 has what effectively works as a thermostat, just like the 5R110 in the 6.0 and 6.4s.

The more basic 4R100 doesn't.

To the OP, on a stock cooler which is about the same size as your keyboard a 100 over ambient temp is pretty normal. A bigger cooler will defiantly help the cause. A 6.0 cooler is a great upgrade, don't get hung up on 31 vs 26 row both work very well and are a huge upgrade over the 9 row 7.3 cooler. Search around online and you can find new ones in the 270-350 range. Mine came out of a junk yard for $100.

Thanks for all the input, I have been researching them. I've read that when getting a used one you want to make sure to flush it really good. Seems like I've also gathered there are some aftermarket ones available from places like Summit, but haven't determined what the general consensus is on those.

To jesilvas, I was on divided highway that has some small hills and scattered red lights, not stop and go but not full on moving.
