Wasn't 4L60E but 8L60E in 15 Silverado behind a 6.2. It developed converter shudder while still under warranty. I thought for sure they would replace the converter. Instead they used some type of trans flushing machine and ran about 25-30 quarts of tranny fluid thru the trans. It worked. Never had a problem after that.
