Hello guys. i just have a question to you coz im just a noob..,

i recently bought a 2008 Honda Civic 1.8 S (automatic). heres my questions:

1. ive noticed that sometimes whenever i switch on the ignition, there is a lag time for the gear to be switched from "park" position to either "reverse" or "drive". in short the engine needs to be warmed up before i can change gear. is this normal for automatic gears?

2. i dont have plate number yet for my car. i only have a sales invoice dated 4/29/09 (date car was released to me). one time, an MMDA officer flagged me and demanded that i should have a some sort of permit from the LTO (no ticket or kutong was given after i promised that i will sort this out with my dealer). my SA said that she is not aware of this special LTO for me to travel using the still the still "unlicensed" vehicle. while im expecting my plate number to be released this week, im just confused and curious as to the real documents needed for the legality of me using the car.

3. is pressing the button in the automatic gear always necessary whenever i changed gear? ive noticed that even if said button is not pressed, i can still change gear from D to N or R. gear will not change only if its from "park" to "drive" or "reverse" during the initial start-up.

Thanks in advance.
