Agree totally with Marshall . If you put atf in small cans and get 4 x as much per oz. you have a way to get a Big Mac . Even further , i once got into what is in the 10w special oil once used in all those semi automatic mopar transmissions ? Turns out nothing . It is 10 w oil . That was the first atf, but you can make more $ by dying it red and calling it “ special atf” . Also one notes the relatively sudden switch among drag racers from “transmission gear oil” in manual trans to using atf now —“ for better shifts” in say a T10 GM 4 speed . Makes sense to me . Mercedes stick I had (ZF) came with light oil . Early 80’s. One thing that is true and we covered before at some point is that new very expensive mopar synthetic atf “ good for life of car “ are factuality better — as they will flow freely at much lower temps — which really matters when you have a very fine filter mesh in the trans , apparently part of the lifetime sealed concept . Early TF have a rather crude metal mesh , so not bothered too much by thick oil .but such thick oil when cold might not make it though a modern filter . 727 filter may be in between. Old way works fine ... but : On a few cars with iron trans I did put an inline fine filter on cooler line and used the big buck atf . Seemed to be fine . 62 727 was that way stock , along with an inside filter . Also I do that on coaxial ps box , Do not want that to act up , or get wear junk back into ps pump . Or replacing failed ps pump or trying old pump again . Sometimes hard to know what to do on that , but protection helps . I appreciate and accept other’s opinions on all this , but did read about this fine filter / low temp issue in an SAE article . In any case cleaner oil is always more better . Plus latest stuff probably better in many parameters than that “red 10w oil” But-to each his own . All info helps... Although details escape memory I remember reading too about some guy crossing F and GM atf to “ get better shifts” . One school likes smooth , one likes fast and solid . I love the 62 727 shift , solid kick down all that stuff . Can’t stand part throttle kick down “ they “improved it “ with . You could feel passing gear detent then , had control by your foot . Better ...
