Zf5 fluid

[swamp_ratt]

What does everyone run for fluid in their zf5's? I'm going to be changing the fluid in mine chasing a 4th gear issue. Typically I run bar and chain oil in my manual transmissions. Interested in what all you have found works well for you

Atf in mine.
Someone just started a thread on this the other day.

All you are going to do with running a thicker oil than is recommended is mask the problem that you already have. It won't fix anything and I doubt that it will allow the transmission to last any longer.

I just run synthetic ATF from Walmart and have had no problems with it.

Hey, if it masks it for about 6 months, that's all I care! It pops out of 4th gear coasting once it warms up. Cold it doesn't do it. Only done it since my engine swap

Perhaps that is why he is having a problem.

Right, it's close to 30wt but it has that **** in it that makes it tackier so it sticks to the chain better, can't imagine having that **** inside a transmission will do it any favors.

you do realize that oil is designed to stick to metal right?

The ZF-5 uses Synthetic ATF. If you want to use something more viscous, use the RedLine MTL as previously mentioned. The factory actually uses an Allison-spec'd synthetic ATF, Castrol TranSynd. Cheers!

Yeah I'm aware of that, but I see a sticky, gooey mess with that stuff contained inside a hot transmission with no way out.
