If the fluid in the Lippert level up is clear it is NOT transmission fluid…

It is AW32 hydraulic oil.. nit all Lippert level up systems come from factory with Red ATF.. it depends on the builder and what they use..

My 2014 Keystone Alpine has clear fluid and is most certainly AW32..


Here is LCI official list. I am NOT a Oil engineer or expert on HYD oils but I can read and follow directions. I am also a Master Certified RV Tech with factory training in both LCI/Powergear and HWH. In ALL training, they stated to use Dexron 3 and NEVER TO USE HYDRAULIC FLUID. I have worked on both HYD Jack and slide systems for 35 years. If this list shows AW32, please list which it is. CLEAR Transmission fluid is available from HWH. It IS Dexron 3 without the red dye. You cannot look at clear(gold) fluid and state it is NOT Transmission fluid. Doug

PS for very easy use, just use Dexron 3

ATF has a very distinctive odor, you should be able to recognize it pretty easily. if you aren't familiar with it, just check the transmission dipstick on your car. Take a wiff of that, that odor is very distinctive, hard to miss even if you have a bad sense of smell.

Also, this isn't a very demanding application, it's not like its a tractor digging or moving dirt all day long; it's not going to make a huge difference what you use. There is not a lot of danger in mixing common oils like this, the additive chemistry may not be a perfect match, but there shouldn't be a problem with negative reactions occurring if you added ATF into a system originally filled with anti-wear hydraulic oil, or vice versa. The important thing noted in a message above is DO NOT USE BRAKE FLUID!. Brake fluid is a particular type of fluid that if you added it into your leveling system it would damage the seals and you'd have to have the entire system rebuilt.

Both HWH and LCI state, that if you use the wrong Fluid, it will cause problems with the operation of the seals and/or leaks. Doug

OP, you have to check the level when everything is retracted.
I’ve never even seen camper hydraulics but I’m sure they work like any other. And half full tank with Rams extended sounds aboot right to me

Interesting. AMZ/OIL is on their list. I used it right after delivery in 2015. Guess my recommendation is approved.

Make sure all your hydraulics are retracted...slides in and leveling system is up. Then check level. Our Lippert system uses auto trans fluid.


X2 Makes a big difference in the level in the reservoir.
