After a 5 hour drive I noticed that when I start up the car and I shift from P --> R it makes a gear grinding noise. Is it my transmission that got damaged? I don't see how I could have damaged it. I was driving very casually with no redlining. The only bolt on mods are HFC, CBE and K&N Intakes. If it is my transmission, my warranty should not be voided due to the bolt ons if I call the dealership right? Its a fairly new 2010 7AT with ~5000km.
