I parked the truck for the winter in November 2012. when i started the truck in February 2013 and after letting it idle for aprox. 20 minutes, when i put it into gear, nothing happens. The idle will change slightly butit is like it is in neutral. Everything worked when I parked the truck and i had the trans. serviced at a Dodge dealer about 8K to 10K miles prior. Never had any trouble before. The codes that came up were: P0700 and P2299.
