How are Trans Oil Cooler Assembly issues diagnosed?
There are many problems that can arise related to a transmission. Some of them can stem from a bad trans oil cooler assembly. But to diagnose the assembly itself, a technician will first check the trans oil level. Then the vehicle is lifted and supported to gain access to the cooler assembly. The cooler and the supply lines are checked for leaks. A technician may flush the lines and the cooler assembly to make sure there are no blockages present that might restrict the flow of trans oil.
How are Trans Oil Cooler Assemblies replaced?
If the trans oil cooler assembly is damaged and leaking, or if it has an internal blockage that prevents oil from flowing, it will be replaced. To do so, the technician will drain the transmission oil. Any accessories that are in the way of access to the cooler assembly are removed. On some vehicles, disassembly can be significant. The supply lines are disconnected and the assembly is removed. With the new cooler assembly in place, new seals (and maybe new supply lines) are installed and fresh transmission oil is added.
RepairPal Recommendations for Trans Oil Cooler Assembly issues
