Honda civic transmission automatic are they good do they break down from 2000 to 2004 are they reliable

 

Honda parts are generally built pretty good, they should last easily to 100K miles. That being said, no matter how well built the part it, it is only as good as it is treated. If you sit in stop and go traffic all the time, that will lessen the life. If you don't change the fluid every so often, that will lessen the life. If you do neutral drop burn outs and run it to the redline, you are asking for trouble.

So much of the answer to your question would be based on you.

 

Did a quick browse of ratings on Consumer Reports and as tpb suggests, they are pretty reliable. The only blip in CR's chart was for 01's that were sub-par for some reason.
