did you read the whole paragraph regarding dexron? It says to use it as a temporary solution and to refill with honda ATF. Its temporary not permanant.

feeling & knowing are two different things.
You may feel it's better to use synthetic ATF but we know that honda transmissions are sensitive to other non honda - ATF fluids but, since we arent responsible if anything goes wrong go right ahead and use the non-honda brand. Just dont bother posting messages as to why your car is shifting funny, slipping and or giving you problems. We're giving you advice on what to use. If you hesitate to believe us please do a search to confirm this.
