Can you shift the civic like a manual transmission on an automatic transmission with the gears 1 2 D3 and D4 but without a clutch while driving or will this damage the transmission

it's mostly designed to be used for snow conditions to keep in lower gears.

Ah that makes sense, but can you shift throughout gears in the automatic through a daily drive or will it harm the suspension, is a better way to ask this

not sure, I leave the computer control it on my only auto trans car. Computer is smarter than me (except in extreme conditions that require visual confirmation)
The only car with auto trans I have is for daily commute (much easier for stop-go traffic, last thing i want to do is shift it myself). No allures in shifting an auto trans by myself.

Mind you, most of the techniques involved in shifting a manual trans involves the clutch.
Shifter techniques are also absent in auto trans.
Nothing really to be gained by manually shifting an auto trans other than extreme conditions.

No unless you like replacing transmissions. Just let the car do it's thing.
