What's up with the current Honda auto tranny?

[Trex101]

I have found a disturbing trend while surfing through BITOG UOA section. Honda tranny now a days is not build to what it used to be. There quite a few reports of bad UOA and decrease OCI has been recommended for apparent design problem.

 

Some sample of Honda tranny UOA.

Honda ATF-Z1 is no longer recommended or use by KM/outside workshop anymore. It's been replaced by CVTF/HMMF.

CVTF/HMMF is for the CVT tranny, ATF-Z1 is still recommended for the normal auto transmission.
