Hey, I have an 08 g37s coupe with 70k miles. When I start the car, I always let the car warm up. If I put the car in drive or reverse, I hear a sound like my gears are grinding or soemthing. The car always
Kicks. I'm scared for transmission is going. Is it a transmission problem? And also anytime I'm driving and I go over a bump or hit a small crease on the road I hear a sound from the front passenger suspension. The suspension noise comes and goes.

Isn't my tranny under warranty for 100k miles?does anyone have any ideas? I really don't want to replace the transmission....


Thank you
