2004 GP GT - Hot Tranny

[Seven]

I have a 2004 GP GT, with the trip computer. I find that the tranny seems to run hot, like 90 to 105 degrees C. Is this normal? I do mostly highway driving and the tranny will reach these temps even if I am not in stop and go traffic. Just recently I had to pay $2900 to have the tranny fixed, they replaced the torque converter, clutches, and all solenoids and switches. After this repair I still find the tranny running hot. I even have an after market tranny oil cooler installed. The impression I have is that the tranny cooling system is not working or very ineffective.

Does anyone hvae any comments or ideas on things I can do to get my tranny to run cooler?

you've done what you're supposed to do. Perhaps the lines are clogged?

Well, I'm going to take it back to my tranny guy and ask about that. I would still like to find somebody with same car to see where thier tranny temp sits.
