i changed a 700r4 recently and didnt get enough dex3 to do the whole job as i drained and refilled the tc several times to remove all old fluid.the old stuff was thick and brown.
i noticed that the advance auto stuff smelled like oil but the walmart super tech smelled like celery.
any problems long term with additive clash?
any sudden change in base/adds recently?
 
DexIII-h might be considered a "change in base/adds".

I don't see any problems with additive clash. I also don't use cheap ATF's longterm.
 
VII's smell different they do the same thing tho. Most PMA's have a plastic or celery smell I think OCP's can be used also they smell burnt or oily to me.

Look under "question of the day" folder, modern ATf's have about 15 different base and add chemistries in a typical formulation IIRC.
