McKinney tech says it's a syncro sound that i'm hearing. normal, not fixable. I asked if it was ready to pick up and he said no, they will call me when it's ready. He said they have to close out the ticket, quality control...etc. I have a former mechanic friend who says it sounded like a problem to him. he suggested calling around to other dealers. anyone ever hear of the normal syncro "grind" when shifting into reverse???
