There is no problem as 180 to 190 is quite normal and will not harm anything. Generally you want to see about 200 or less and at about 220 and above you want to let it cool some if you are pulling it hard. (gear down and slow down) When you start getting to 240 and above, you can do some damage even though it may not show itself right away.

What Sno said, ditto.

and..... how do you KNOW it's 180-190 degrees? (jest curious)

My truck has a tranny temp gauge.!!!! I'm glad to hear it's all OK as I plan on pulling a 6x12 enclosed motorcycle trailer soon. Thanks guys...as always.!!

Your temps are ok. I pull a 7k lb. travel trailer at interstate speeds and my temps rarely go over 200 f. Most times it stays around the temps you mention. In high desert, high alt. areas(summer) which I try to avoid, is when the temp goes a little over 200. MR
