alright I just got out of my car, and I noticed when I shifted from D to P I hear click noise, so then I shifted to Reverse I hear it again, its the gears changing, but its loud enough for me to hear, now am I paranyoid or is my tranny about to go, and I just had it replaced 6months at my own expense b/c I went way over the 100k miles warranty, is this normal to everyone else?

 

Normal.

 

if u DO NOT hear that sound then your parking mechanism is not engaging properly on the tranny.
