The Dealer is slowly making progress on the 2nd gear problem. Finally had the right "tool" overnighted to open the tranny (this is a big Dealer too!).
The update is that the Second Gear Syncro is not broken or cracked, but simply "worn out." In 6400 miles!!!!!!!!!!!!!!!!!!!!!!! With no speed or power shifts and not track visits to date!!!!!!!!!!!!!!!!!
He remarked that my rear tires were showing some wear. I explained: (1) soft compound for performance; (2) the RPO Z06 is made for performance--this is not a Camry; and (3) there has been absolutely no abuse on the car.
There are no problems with the dealer, but it does bother me a bit that a part like a tranny syncro will wear out in 6400 miles. I cannot believe GM planned this.
Also, nothing new on oil consumption yet. GM is looking into it.
