usually once a year with honda atf only. i also have external honda filter and B&M cooler. remember you are only changing 3 out of 9 qts trans fluid. so its better to change it more often to keep new fluid in there. these are prolly the worst auto trans honda ever made (01-05 models). even with all my careful driving and extras, its still on its way out soon and will need a rebuild.
Thanks gearbox, I tried looking for the OEM external filter kit, but haven't had much luck. I read that you got it off ebay, and it is off a CIVIC HX with CVT. I was wondering if you still had the sellers info, store name, or anywhere else I could find it?
yeah i usually need a new dipstick every 6 months. the rubber just keeps getting smaller til it almost falls out, and then i have trans fluid going all over the place. i fit the HX filter on my EX with no problem, there is a good spot to mount it and then you just splice it into one of the trans oil cooler lines. here it is next to the header.
i did somewhere, im not sure where and if the pics work. but basically you can get a small B&M unit, wedge it in-between the condenser and radiator without bolting it in, then run the trans cooler lines to the aftermarket cooler. so pretty much i have my one cooler line going out to the radiator stock cooler first, then going to the trans cooler, then to the filter, and finally back to the trans. according to honda manual, line out is on the left when looking at the engine bay from the front, the right side is the return input back to the trans after being cooled. since the stock radiator cooler is a joke, you want the fluid to go to that cooler first, then to the aftermarket version. that way you have some cooling of the fluid. the stock cooler doesnt do anything because usually the coolant is the same temp as the trans fluid, or higher!
some pics, be sure to use real transmission oil cooler hose when making the connections. do not get generic or fuel hose. you will have a big mess when the rubber gets eaten away from the inside and goes into the fluid.
these are the cooler lines coming from the trans. left one goes down to the radiator, then back up to the right side.
I haven't read this thread quite a while. Thanks gearbox!! that looks very neat. I'll check and see if i can put that one in too. My new trans dipstick works very well. It holds a lots better. But I have to clean up all the fluid. It looks pretty dirty around the dipstick.
just look up the "ATF cooler" tab on majestic honda (www.hondaautomotiveparts.com) for a 2001 civic HX with CVT trans. you want the filter and also the brackets that hold it in place.
Thanks for the information gearbox. I ordered the filter, bracket (2 piece set), and 2ea oil pipe clips.
I'll install it on the return line, the pipe on right when looking down facing the engine from the front. At this point no plan to install an extra cooler.
about the ATF, I did change ATF 6 times already. Now, it's about 79K and the trans is still running ok. Now, I am using Volvoline Maxlife ATF instead of Z1. I think I might suffer the MPG but I have to find the way to measure it systematically. I could be my driving habit also.
Ok...I'm most likely going to be buying an 02 Civic EX, with 78,800 miles on it right now.... Current owner has had standard maintenance done at the dealer, oil changes, brakes, etc. Not sure about the trans.
Assuming the trans fluit has NOT been changed at 78,800 miles, in Houston TX...is it still safe to change the fluid now? Or will it certainly ensue future damage?
once a year. for you, check the fluid condition first. if its dark black or brown, i would not risk changing it. you could get another 50-100k out of it on the original fluid. if the fluid looks red, you can prolly get away with a single drain and fill. then start yearly drain and fills.
Now, why is it that everyone says to use Honda fluid only. I've recently changed my fluid 3 times to get most of the old stuff out. I refilled it initially with Honda ATF for the first three quarts. I was given this by a friend, but the remaining times, I filled with Castrol Import Multi-Vehicle that said it meets the requirements for the Honda fluid. Is this bad??
