Proper oil for 378 leveling system

[wvphil]

I have three questions on different subjects so Im going to post three times since different subjects. Anyone know correct type of oil for 378 leveling reservoir? Also should it be checked with all slides in and jacks up?

You do check the level with the slides in and the jacks up. It takes a standard ATF, I had to add a pint on a new 377 to read at the full mark. That is the way it came from forest river.

Micron 2 ATF is what I was told, just have everthing retracted and be on level ground, fill enough to leave space in tank I think it's 1/4 ....

On the Lippert website , there is info as to which ATF to use .They specify two types,I think mercon 3 & dexcon 4 , don't remember exactly,but that is what you want to use. Fill to 3/4 in. below fill cap on side of tank.
