Retract everything, then check fluid level in the hydraulic resivoir

You have leaky valves for those Jack's, the valves are on the manifold at the pump
If low you have Jack's that are leaking fluid
If so you should be able to find red ATF fluid on the Piston or fitting that is leaking
Retracted as you suggested. Reservoir is a little low but not much. I checked for the red fluid and found none. I tried auto leveling again, that was 15 minutes ago and so far, it is holding fine. Could it be Gremlins?
1. RED ATF may not have been used. Most OEM's use HWH fluid which IS ATF without the red dye. That means the fluid is clear like motor oil, you still look for wetness.
2. EACH Jack has a solenoid. So, if you have ANY Jacks that settles(raise up) or comes OFF the ground a few inches, that is the solenoid/s leaking internally
3. What I do when this happens is to open all 4 solenoids manually and run the hydraulic pump for about 30 seconds. That allows any possible trash/debris that may have stuck in the solenoid needle valve to be flushed out. Once you do this close all 4 solenoid valves and retest. IF you have a jack that still settles or retracts and NO visible leaks, then the offending solenoids will have to be replaced. Doug
