Sometimes debris gets trapped between the AC condenser and the radiator. Check that.

Change coolant, if it is due, and consider going to a cooler thermostat like a 170 or 180. Make sure to burp any air out of the system. If air gets trapped, the cooling system won't cool properly. Also, wire the fan(s) with a switch to turn them on early.

Install a trans fluid cooler in addition to the one in the radiator. A cooler trans is a cooler radiator and engine.

As a last resort, turn off the AC before you begin a long pull up a grade. A cooler condenser is a cooler radiator.
