Re: !st gear popping out
Read the TSB attached, check that the transmission is adjusted properly as I doubt that it has gone on for nearly 50,000 miles without a cure when it was new and done for no charge.
I found on the manual tranny I had on an '04 that if I did not put it fully into position it could pop out, maybe that is your problem.
