hydraulics in cold weather

Does cooler weather typically effect hydraulics operation. Winterized my unit last week and when I tried to close the main slides (hydraulic operated) they would move about 6" and stop and the touch screen would say "Fault occurred" I could release the control and touch it again and it would move about 6" and do the same thing. I'm thinking it was just because the fluid was cold and a little thicker. Does this seem typical and if so, is there an additive to help with this issue?

    My Lippert system calls for Dextron ATF. I long ago removed it and refilled with AMZ/OIL Signature Series ATF with zero issues that many have experienced like popping.

    I will say that my limited exposure to cold weather camping has been exactly that.

    My jacks would NOT completely go up the first time.. The first time it happened I was concerned, but after asking on forums found it was normal. I have NOT experienced a slide issue as of yet due to cold/thicker Hydro fluid

    Cold will make hydraulics work slow. Some hydraulic systems use various types of fluid which effects system operation.
    What system do you have and what fluid is in it?
    Some hydraulic systems, not nessesarily rvs, have screens on the intake to the pump that can become restricted.
