I have a Honda Civic 7th Gen Vti Oriel Prosmatic 2003. I previously used Honda ATF in it. Last transmission oil change was done quite late so this time im replacing it after 6K, in order to flush it earlier. All the mechanics advised me to use original Honda oil but for this time im inclined towards Liqui Moly ATF III. All those having experience in automobile can guide me better.
Plz also tell me how to flush transmission oil, as it can't be done like u do with engine oils by keep the car idiling in "P" or neutral for 5min after putting 1-1/2 litre fresh oil and then changing it with new oil.
