C- Turn off the overdrive, and E- put in an aux tranny cooler.

Turning the OD off will keep it in 3rd and will keep the torque converter locked up longer than it does in "normal" mode. TC lockup means less heat.

The higher RPM's are no big deal, these engines love to rev. You may even get better gas milage too since less is wasted as heat and the higher RPM's are more efficient. Its just noisier.
