The newer trannys seem to run hotter by design. The fluid is better and tolerates more heat, and I think the overall efficiency of the vehicle goes up as the fluid temps do due to less resistance in the driveline.
My truck usually gives me around 90*C when driving unloaded in the summer, and about 95*C when towing. I've had it up to 102*C once or twice when pulling steep hills slowly but even that doesn't concern me. I have also heard that 110*C or 230*F is when you should start watching things closely.
Even at 102*C (digital readout) the analog gauge didn't move a hair from the normal middle position.
