Indefinitely. Longer if you get the leak fixed sooner than later and never let the fluid level get too low.
You don't. Most Honda transmission have a non-serviceable filter that is located inside the transmission. The transmission must be disassembled to get at the filter. It is designed to last the life of the transmission. By the time the filter is clogged, the transmission needs overhauling.
2.5-3 quarts. After the last fill, use the dipstick to verify it's properly filled. Honda (unlike everyone else) wants you to check the transmission dipstick with the engine warmed up but NOT running.
Inside the transmission. This is a non serviceable item. The transmission must be removed and broken apart to access the filter. No need to worry about it. When it needs replacing, the transmission will need rebuilding at the same time. Change your fluid as outlined in your owner's manual, and it will last for the life of the transmission. Use only Honda transmission fluid no matter what anyone tells you!!! Honda's shift better with OEM fluid.
Use ONLY genuine Honda ATF-Z1 A/T fluid and nothing else. Do not listen to anyone who tells you that you can use any other fluid that claims to be compatible. DexronIII can be used in an emergency but must be removed ASAP. Honda fluid is not cheap but way cheaper than a new transmission. The 2003-04 had a recall on the transmission for poor lubrication of one of the gears. Make sure the recall has been performed on your Honda. Change the fluid every 50,000 miles religiously. The 2003-04 Accord transmission is the weak link in these Hondas. I know as mine went out at 70,000 on my 2004 Accord. Honda replaced it as free of charge as I had a certified used Honda extended warranty of 8 years 80,000 miles. They have replaced many of these, so be forewarned and take care of yours and hopefully it will last.
The 2009 Honda Accord 4 cylinder does not have a belt. It has a chain that should last the life of the engine.
The best transmission oil to use in any Honda vehicle is the Honda brand. This transmission oil is create to supplement Honda's design and is proven to make the components last.
There is no such thing as a V4 Honda Accord. The 2004 Inline 4 cylinder Honda Accord has a timing chain and it is not an item that you replace at a set interval. Normally it will last the life of the engine. The V6 has a Cam Belt that must be replaced every 110,000 miles.
All Accords sold in the U.S. are made in the U.S. Last year, 2013 a grand total of 466,695 Honda Accord sedans and coupes were produced at Honda's plant in Marysville, Ohio.
I am on my fourth Honda Accord and they are just about nicely broken in at 100,000 miles. A properly cared forAccord (very important, that!) will easily last 150,000 - 200,000 miles.
The 2002 Honda CRV does not have a belt it has a chain which is designed to last the life of the engine.
The chain, if equipped, needs no replacement and will normally last the life of the engine.
The timing chain on a 2006 Honda Accord 4 cylinder is designed to last the life of the engine and is normally replaced during a complete engine rebuild. No scheduled maintenance is required.
