(1) TEHCM Screen Filter Assembly (brown)

Tech note from the trenches:  
These MUST be replaced any time the TEHCM Assembly is removed because the seals around the ports take a "set" when assembly is torqued to spec (squashed into place, don't spring back). Re-using what looks perfectly fine can and often does result in pressure leaks and false solenoid switch codes and potentially catastrophic results by rolling the dice. 

These are purchased in bulk from the OEM for GM = no "Parts Counter" packaging
