[QUOTE=98CoupeV6]Uh no, any sort of oil additive is a waste of money. It is tranny death to use anything other than Genuine Honda ATF. People have had their trannies go very very quick because they had the tranny fluid replaced with non Honda ATF.QUOTE]

I agree with that but his tranny is on its way out. There are oil treatments for slipping transmissions and they help with slipping only.
May be I wasn't clear in my previous post but I was talking only about this type of treatment and they it should be used only when tranny is already slipping.
