05 GXP, althought the warranty is 3 years or 36 months, and I see you have 58,000 miles but I say go and raise hell about that because thats a brand new car and it should not have any tranny problems.
have you ever got the transmission serviced since you owned the car. Like chew said don't ever get it flushed, just change the oil for it.
