Transmission (TBV) thermostat
Own a 2014 Tahoe LTZ with the 5.3 engine and 6L80E transmission. This is a recent purchase at 125k miles. Vehicle runs great but wish to keep it that way as I will be towing a smaller toy hauler. My research via You Tube has shown an upgrade to the trans fluid thermostat from 190dg to 165dg or...- Doc52
