Hi again, all! After much research into issues with the version I 4EAT (on all Outbacks prior to 1999), I've decided that I want to try to improve my existing "Duty Solenoid C" operation (see my earlier 4EAT thread) by a change of fluid. Several sources, including a couple on this board, have suggested that replacing the fluid with a good synthetic ATF coupled with addition of a low-friction additive might be a thing to try before I tear into the extension housing to replace my Solenoid C. I'm willing to give that a try, mostly because nobody local stocks this solenoid (including the local dealers I've tried) and if I have to wait a few days for a part to be shipped to me, I might as well give this a try over the weekend. So my question is this: What's the best (in your opinion) ATF and/or additive to use in my Outback's transmission??

BTW - Subiegal, if you read this post, I have submitted a request for price quote to your Day Job's website -- maybe I can buy my next solenoid from you guys and keep this all "in the USMB family." ;)

Hi,

A really good source for specific information is Redline. If I'm not mistaken, I think that their friction modifier for gear oil is the one you want.

Call them up, they're really good about info. on the phone. Go to their web site for the phone number at redlineoil.com.

Regards,
Adnan
