Car Forum / Honda Cars / July 2006Transmission fluid flush and fill?
How hard is it to flush and fill my transmission fluid? (2003 CR-V). The manual says: "Always use Honda ATF-Z1. If it is not available, you may use a Dexron III automatic fluid as a temporary replacement. However, continued use can affect shift quality...To thoroughly flush the transmission the technician should drain and refill it with Honda ATF-Z1, then drive a short distance. Do this three times. Then drain and refill the transmission a final time. WOW! DO ALL DEALERS DO THIS? Nino > How hard is it to flush and fill my transmission fluid? (2003 CR-V).

Aren't you also supposed to warm it up and run it slowly through ALL gears like 5-10 times for each cycle? Also, for the flushing part, can i use the cheap stuff, Dexron? thanks.

[quoted text clipped - 3 lines] > > Kevin - --------------------------------- Good question, If all your tranny fluid fell out, you could refill with Dexron to get to the Honda dealer where you'd buy about 10 quarts of Z1 to displace the Dexron.. The manual says to "drive a short distance between refills, three times". I drive it a week then do it again, and drive it a week and do it again. The stuff you 'flush' with ends up staying in there, so it has to be Honda z1. 'Curly' So Curly, then does it take you 3 weeks to complete it? I spoke to a Honda technician, he told me they don't do it three times. He just does it once. >> Aren't you also supposed to warm it up and run it slowly through ALL >> gears like 5-10 times for each cycle?

He just does it once. if i'm just after a quick change, i do it once. but if i just bought the vehicle used, and i'm not 100% certain of its history, /or/ it's exhibiting the classic symptoms of having been polluted with non-honda fluid [HARSH shifting], then i'll flush 3 times. /definitely/ use honda fluid though. i've tried ordinary dexron, and trust me, it's not the same. >>>Aren't you also supposed to warm it up and run it slowly through ALL >>>gears like 5-10 times for each cycle? [quoted text clipped - 19 lines] >> >>'Curly' Thanks, just a few more questions before I start: 1.) Do I just undo the transaxle fluid drain plug, and let it drain? For how long? How many liters of fluid do I need? (Since I bought my vehicle new, I'm just going to do it once.) Chilton's manual recommends adding 1/3 of the fluid, cycling the shifter, and then adding 1/2 pint at a time, until the level is correct. Is this good advice? Thanks a million!

Is this good advice? no. with a honda, you just drain & fill. if you drain and leave for say 20 minutes on level ground, simply refill with the amount of fluid per the service manual spec. i'd ignore pretty much anything the chilton says. those books are generic garbage, full of mistakes, and their service language is written for old detroit hydraulic-control autos with planetary gears, not honda solenoid-control autos with standard gears. invest in the honda service manual from helm.com. it's the single most useful tool you'll ever purchase for your honda. > Thanks a million! > [quoted text clipped - 35 lines] >>>> >>>>'Curly' what vehicle? the drain and fill spec is in the service manual I have a 2003 CR-V. According to the manual I need 3.1 liters. Is this correct? Will I have to buy 4 liters of ATF-Z1. Finally, I have one more question regarding my brakes. I drained and filled them using Dot 3 (Napa for ABS system) Is this good enough, or should I have used authentic Hondas Heavy Duty Brake fluid?

Also, I drained 4.1 liters instead of 3.1. I hope I drained the right stuff. What do you think?

What do you think? was it definitely the transmission? normally, fluids are dyed to differentiate them in the event of leakage. atf is /always/ red afaik. regarding the correct quantity, check the dipstick. check the owners manual for the correct procedure here - detroit transmissions require the vehicle to be idling, my honda is dipped with the motor stopped. > Nino > [quoted text clipped - 83 lines] >>>>>>>> >>>>>>>>'Curly' When I did the flush and refill 4 times it took only 3 hours. Drive it around for a bit between flushes. But it was the right thing to do. You should not do the "power" flush on your Honda/Acura transmission. dan > So Curly, then does it take you 3 weeks to complete it?

Then drain and refill the transmission final time. WOW! DO ALL DEALERS DO THIS Nin It shouldent be hard at all on a CRV you can probably crawl underneath and loosen the drain plug yourself but i wouldent use Dexron III fluid not even on a temporary basis. as far as flushing and filling goes that would be the "safest way" aside fro using a machine to power flush your automatic transmission. when you flush fill drive it around for about 3-4 days let the Honda fluid mix in with the old flui and circulate well enough to wash the tranny then drain and fill and repeat th process over. ; -- johnin |
