Been doing some research on the best fluid for my wifes 08 Legacy with the 5MT, its very "notchy" IMO and I Hear thats a common complaint with these boxes unless you put the right fluid in them. I changed it last year when we bought it and just used Valvoline &%w90 GL-5 like it called for but I'm not liking it.
Many say to use Redline 75w90NS, some say royal purple syncromax, some say the Pennzoil synchromesh etc... what will give me smooth shifting and proper protection for this already weak gearbox?
Any personal experience?
