If your car was still on a lot in mid April, it should have been thru RRT#10024 for just that. There was a test to be performed that would have determined if u had a bad casting. If u have the dealer check, it will show as performed on your VIN. They took down the page with the RRT, I can't remember what the test was, but believe if it FAILED they were to remove to auction, because you couldn't replace tranny and sell it as new? So I know mine went thru it, but not sure they didn't want to replace tranny, doesn't say anything but that it was "performed". But did notice when replacing stock shifter with Hurst, that the lower bolt head, holding the stock rod onto the shifter, would butt the plate and rubber cover in 2cd position, button head bolt would be better there. Maybe the bolt has loosened, not letting u get all the way in gear? Definately bring to dealers attention regardless, CYOA.
