apologies in advance for this post asking for advice. I have tried searching on this forum and elsewhere, and have also called toyota and subaru dealers in order to get a sense of clarity and what seems to work best. i seem to be getting different information about which grade fluid i should be using when changing the fluid for an auto box. according to subaru, it ought to be dextron 3 LX ATF, but toyota say 75/90. both saying around 7.5 litres for a dry fill. for the diff, i've been told 75/90 gl5 lsd type - 2litres. if anyone can shed any light or confirm any of the above, and also offer some recommendations about which grades and brands work well, that'd be very appreciated.
