ATF

a moped that has a 2 speed semi auto (or is that fully auto( gear box that uaes ATF , this is an OLD moped , not a modern rev n go single speed from china 

spec says to use ATF type a MINERAL , type a has long gone been superseaded , and if you follow oil makers trail many disagree with each other 

the bike has dexron type 111 fully synthenic , and its acting up , this must be wrong because a hardy communist bike is objecting 

i can follow links from atf type a to dexron 11 , but it gets hazy in the 70s (wonder why) 
I suspect the friction materials used on the "slippers! in the auto clutch are very much like motorcycle clutch plates and object to oil with "friction reducers " (all car oils ) plus the grade of ATF is wrong - the old type f was used on one version of the bike "more grippy" 

the only atf i see cropping up on cross refs is the comma oils aqf , which is mineral and dexton 11 (not later 111) 

anyone remember the correct upgrade from type a ?

You can get "classic ATF" which is dexron IID.

e.g. https://www.penriteoil.com.au/products/classic-atf-mineral

Dexron IID is compatible with the type As.  It is your best chance now, as you can't get the whale oil any more.

Dexron III introduced friction modifiers.
