Methods and systems are provided for controlling coolant flow through parallel branches of a coolant circuit including an AC condenser and a charge air cooler. Flow is apportioned through each of an air-conditioning condenser, a charge air cooler (CAC), and a transmission oil cooler (TOC) of the coolant circuit to maintain an estimated transmission oil temperature (TOT) below a threshold. The TOT is estimated from a torque converter slip ratio.
