D.3.1.4 Transmission Cooling System<br />
D.3.1.4.1 Transaxle Cooling System (Baseline Fusion)<br />
The baseline transaxle (Figure D-26) is cooled by routing the transmission fluid though<br />
an externally mounted heat exchanger. Fluid is forced through the heat exchanger by the<br />
internal transmission pump. The heat exchanger (Figure D-27) is a traditional design<br />
mounted internal to the radiator tank.<br />

D.3.1.4.2 Transaxle Cooling System (Fusion HEV)<br />
An auxiliary coolant pump is attached in-line on the cooling system for the transmission<br />
control module and DC-DC converter. This pump circulates coolant from the electronics<br />
associated with the hybrid drive and moves it to the exchanger. The exchanger is<br />
mounted external to the radiator ahead of the AC condenser (Figure D-28 and Figure<br />
D-29).<br />
