What's the best trans fluid and fluid additive(if advised) to use?

 

Honda DW1 ATF... no additive require.

 

 

IThat's what I use. Seems to work in my old 2003 TS-S.

 

if you want the trans to behave get the genuine stuff from acura or honda DW-1 atf
its their newer spec and semi synthetic, good for all their older cars with auto trans

a single `gravity drain` and refill takes a tick over 3 qts. Total capacity of trans is 7.3
