Honda是不是只能用OEM ATF？

[YouHi]

我看了几集拆变速箱的视频。一个感受：这么复杂居然可以开十几年基本不出问题。一辆车买几万块还真不算贵。

本田变速箱一贯体质差 有些人关了vcm 还不放心自己还加了at cooler

那再问一下，同样有歇缸功能的gm 雪弗兰的车也要换变速箱油吗？

[ordinary]

必须是honda专用的 ATF 或者cvt fluid

Honda 有两个transmission filters
最好都换

AT cooler这个我看不少人弄，我个人看法影响不大。

本田变速箱最大的问题其实是过滤器内置。我大概10多年前曾经大修过一个02年雅阁的变速箱，大概15万mi，那个变速箱整体状况还是可以的，唯一的问题是1-2档的slip。拆开检查发现几乎所有部件都是完好的，valve body也并不脏，1档和2档的离合器片稍有磨损但是大多数片都是好的就是有那么两三个disc磨到金属了。最大的问题是filter被堵死了。我当时都怀疑就算我只是把变速箱拆开换个filter可能就能正常工作。当然为了一劳永逸做了个thorough的cleaning把所有的离合器片都换了新的。

据具体行家们说是torque converter

VCM allows the TC to slip in order to buffer the transmission from the engine. That creates heat and breaks down the ATF sooner.

I have to say this does not make much sense. At cruise, the TC should be locked up for improved efficiency. Generally the TC is only in the slip mode for torque multiplication at low vehicle speed. Presumably if running on 3 cylinders do not provide enough torque, the TC can be put in slip mode to output more torque to the axle. However, it should be easier and more efficient to simply switch back to 6 cylinder operation. I just do not see a legitimate reason to run in reduced engine power with VCM but put TC in slip mode for more output.
PS. I believe the honda DW1 is conventional but the Valvoline is full synthetic. The valvoline should be a better fluid.

Synthetic is not necessarily better than conventional in terms of transmission fluid. The benefit of synthetic is that they can meet multiple specs with one single fluid. But I always believe a fluid specifically designed for one application is better than a one size fits all.

有的可能有2个，我上次弄的那个6代雅阁的变速箱我记得是只有1个的。另外还有个磁铁，上面都是铁粉。

其实变速箱只是valve body看上去复杂，其他部分还好。实际上valve body里面的油路看上去蜿蜒曲折的但实际上挺简单的，设计成这样只是为了各个solenoid驱动的油路有固定的长度和截面。

这个YouTuber一直说valve body是个analog computer。

我的感觉是这么多年了，为什么变速箱还用clutch pack这种设计上就有易损件的东西。一个变速箱里三四个clutch pack。每个clutch pack有四五个steel plates和四五个friction plates交替叠合。正常使用friction plate上面的东西也会磨损掉下来堵塞filter。咋就不能发明一种无损耗的变速箱呢。

外面那个engine bay里埋的很深 不好换
filter是旁通的 堵了就bypass了
可能不好换 本田就干脆不换了

我这次drain and fill，发现drain bolt上面的磁铁有少许黑色金属细粉。心中一惊。后来google一下发现是正常现象。

我第一次换的时候 厚厚一层泥 还不到3万

每个model不一样的。反正我之前那个02年雅阁的变速箱是没有外置filter的。我记得听说过后来有些honda的变速箱model给加了个外置filter可以换的主要是很多人意见很大。
