High Transmission Temps?

[johndavidwright]

I'm sure this has been posted but couldn't find it after searching for a little bit.

I have a 70264 SuperCooler on my 99 SR5 2WD and I'm bypassing the stock radiator, just to prevent pink milkshake. I'm in Birmingham, Alabama and temps since I have installed the supercooler have been at max 75 degrees. I've seen my scangauge read the trans temp 185 and I've seen it that high multiple times just driving around the city. Birmingham isn't flat, but not mountainous at all. These temps seem pretty high to me.

While I'm driving on the interstate at 70-80mph, temps are more around 125-150 depending on the day.

Any ideas? Am I concerned for no reason? Do I need to buy a fan?

Help is appreciated!

Make sure the cooler is mounted right up against the condenser in front of the fan.....

Your temps look fine to me.

I just got finished towing a Uhaul 6x12 enclosed trailer, filled with heavy boxes and furniture. Also had the rear seats folded down, and loaded up with heavy boxes in the back. There were a lot of rolling hills on my 330 mile trip. The first part of the trip was on a state highway, so 60mph limit, there was a lot of downshifting going up the hills. My trans temp typically got up to 220 degrees while pulling the hill. Once it got up to 230 on a particularly long hill. After I crested the hill and the torque converter locked back up, temps would drop back down to 180.
