Would you be able to substantiate any benefits with documentation concerning the the benefits of the ATF in the primary? I've heard a few tout the benefits but never seen any positive documentation other then "it works for me" type of comment. Certainly the engineers can make a mistake but I'm quite sure they know just a tad more than the average Joe that feels because an automatic trans in a car (which has a pump to pump the fluid under pressure) that the same fluid is OK for a primary chain case of a Harley.
I am sure if you do your own research, you will find that some people HAVE tried just such things, and have not found them to work. I also do not see people on this forum recommending these products for your exampled uses, either, as sometimes it does not take an engineer to find out that something works, or does not work.One question I always ask and never get an answer to is why wouldn't you use fork oil in a transmission of the Harleys or why not use transmission oil in the engine?
And there are examples of such vehicles running fine many miles later. but remember, it was an engineer that made that decision that your particular tranny use ATF. I will take the chance ( since I do not know you or what you do for a living) that your not an engineer, yet you found better results by not using ATF in Dodge trannies. you found it worked better for you. Same here with ATF in primary. Sometimes, engineers just get it wrong, and common folk like you and I get it right.Speaking of ATF in a standard gear box, In 1975, I made the mistake of buying a Dodge van which unknown to me ran ATF in the standard box. Well , long story short, 3 transmissions later, I sold that poor excuse for a van. Some things just shouldn't be.
(certain aftermarket HD clutch makers) has indicated that ATF would allow their clutches to work better, so they recommend ATF.
I can't imagine why.... How about they weren't made for the application?I am sure if you do your own research, you will find that some people HAVE tried just such things, and have not found them to work. I also do not see people on this forum recommending these products for your exampled uses, either, as sometimes it does not take an engineer to find out that something works, or does not work.
...ATF comes in different "flavors" Dextron, Type F, Honda, and others which were for the type of clutch materials used and weren't "cross compatible".
