automatic transmission fluid

[dinanm3]

I 'm swapping my tranny to another auto since mine died.
I will replace filter , gasket rear seal.I want to know a good trans fluid alternative to the expensive redline ,amsoil .
I know it will need 8 quarts tranny.
and also 2 quarts diff 3.73 from a 1987 convert.
My car is a 1988 e30 325 eta stroker.
Thanks for advice.

just use plain Dexron III. Cheap and easy to get at your local parts store

I swear by amsoils syn. universal atf

I'm sure its good but i think its so expensive i'm buying the tranny for less than what amsoil or redline would cost me.
they are around 10.50
and other products 2.97-4.00 x8
thats 90.00 vrs 25.00
I don't think it makes the difference between a working and non working trans
the dexron III what brand ?is one better than the other?
