Thread: Allison TES-295 spec and ZF 4HP22(e)

Question for Rick, any compatability issues with sticking this stuff in a ZF?

There's generally 2 products available being Delvac synthetic ATF and Castrol TranSynd.
I'm looking more at the hydraulic performance of it due to it's slightly higher viscosity rating but can't find anything relating to a DX III compatibility anywhere.
I've got the Mobil ATF in the D2 at the moment and I swear it's making the trannie a lot doughier although the shifts are almost as smooth as the ZF in my Classic.
Just wondering if it will make the converter a bit sharper.....

I had a real slushbox before I had it rebuilt. Was suggested to try Penrite SYNATF and it was a different box. Turned out not to have needed 3K worth or rebuild but at least it's a known now. Stayed with it since and despite cost and being told it doesn't need it changed after first 10000k's and was clean as. Replaced anyway and been perfect for another 10000, will be getting a sample soon to compare. Researched and meets all specs as best as can tell.
