I have searched and get mixed info. My car is on a lift as I try to cobb together lines to fix my SLS. I have to be off the lift before the shop opens on monday and I can't just buy SLS fluid at the local auto parts store. They look at me like I am crazy. I typically order it through a parts supplier but it takes a week. I am looking for a back up option as time is an issue.

My other thought is that someone else is going to reference this thread and need conclusive options and compatibility info to resolve their last minute emergency.

Thank you all for the help.

I now need to know which port on the back of the valve is pressure and which is return.
Anyone know?

That is the philosophy which I go by... being considerate of those reading the threads later on and possibly being led astray...that is why I stay in some threads longer than many think I should.. because I worry that dropping out will look like the disputed information is acceptable .. rather than realizing I just gave up due to someone not being able to understand the physics of the situation..

Just DO NOT use ATF ! .

The boob ' mechanic ' used it in my Euro 300TD and I'm so lucky everything still worked in spite of a thick coating of brownish mud in the reservoir...

I had to dismount it to clean it properly before I flushed the system and I keep a sharp eye on it in case some sludge shows up .

$8 / liter isn't too bad , once you've flushed it and changed the filter it should last several years before needing changing again .
