i had that same exact problem. they were changing out my starter and when i picked it up and drove out the dealership there was a lot of play in the gear, like shaking it side to side as if it were in neutral but it was in gear. i turned around to go back to the dealer and they said thats the way i brought it to them. i said [censored]. then i have an fc shifter and they blamed that next i said [censored] cause when i drove it in there it wasn't like that so they tried to back the car out to say it wasn't their fault and they couldn't back it out. so after about a minute they called me over to back it out and i got in figuring jeez they must have the same problem a lot of us svtf owners had the first time driving the car and putting it in reverse. well i went to push it all the way to the left and there was no click or resistance going in to reverse so i pushed it up and it was in fist reverse was gone i tried again and again and again nothing so i hopped out and said well i must have brought it to u guys with reverse broken too(you know how us focaljet members do it with the [censored] smartass lines) and they said whoa sorry. well sorry i'll get to the point now, but there was a clip that they broke while changing the starter it looks like a white plastic hook idunno howelse to explain it but hey maybe that what it is.
