The “stiction” fluid add is mainly for the six point hydraulic level up. I’m on my sixth season with all hydraulic slides and leveling

I replaced the hyd reservoir fluid 2 years ago ... just siphoned out as much as I could without introducing air into system.

I use AW32 fluid in mine. Not ATF

Well put pump back in this weekend and still has same problem, I have run the slides in and out 4 times and still the same problem, how long does it take to get air out of system? The other thing is a couple times when running out the slides the bedroom goes out first then the office then last the big superslide on the same side as the bedroom slide. The bedroom would come out and the other two wouldn't move then after just touching the slide in button and then out again they would come out. This thing really has me puzzled and after paying almost $300.00 now for diagnosis that haven't worked I am a little gun shy to take it anywhere to be so called fixed. Also if I leave the slide lock knobs open on the side of the trailer and after retracting all 3 slides the bedroom slide will come out about 8 inches the superslide will come out a couple inches and the office slide will come out about 3 to 4 inches, if you lock out the bedroom and superslide the office slide will creep out about 6 inches whether it is locked or not.

If these are opposing slides it sounds like the same problem I had. Problem was a bad piston seal on the drivers side slide cylinder. Opposing slide share the same pressure and return lines. Losing pressure thru the seal will cause pressure drop on both slides. Fix was to replace slide cylinder. Keystone has a test that can be done using the system onboard. Contact them for test procedure. How do I know this? I sent three weeks in Billings MT. getting this fixed under warranty. Hope this helps.
