March 8, 20179 yr What are you using? The manual on the vertigo site specs a Castrol synthetic ATF (the closest thing I can get in the US is Mobil 1 Synthetic ATF). The US importer seems to recommend a Maxima 0w10 (no idea why). A close US dealer runs regular ATF. Maybe anything vaguely oil like will suffice. Edited March 8, 20179 yr by heffergm
March 9, 20179 yr Maxima 0w 10 is virtually identical to Castrol synthetic ATF. Regular ATF (Rather than the most recent synthetic types) will not provide the same level of protection.
March 9, 20179 yr There are any number of synthetic AFT's available. Try something exotic like Royal Purple or Amzoil.
March 9, 20179 yr Author Of the synthetic ATF brands I could find spec sheets for, only Mobil 1 had basically the same numbers as the Castrol. I have no idea how (or if) the maxima compares, haven't looked to see if they publish a spec sheet yet.

How did you come up with a hypothesis that a synthetic fluid engineered for a hydrualic application (automatic transmission) is the same as a synthetic fluid engineered for a gearbox with clutch application?

Have you looked inside an automatic gearbox multiple wet clutches with friction material similar to that used on multiplate trials clutches and numerous epicilic gear sets doing much more work than a straight cut trials dog shift box with minimal hp

By whom I have no idea. Based on the numbers, I'm more inclined to run M1 simply because the viscosity numbers are closer to the Castrol recommended in the manual, and the fact that any additive package in the M1 is going to be more similar to the Castrol, being that they're both ATF.

ATF oil does not has similar charicteristics in the way of shear, foaming, stiction. Amongst other things an automatic transmission uses hydraulic pressure through its passages. Two completely different applications.
March 9, 20179 yr Author I have no idea what you guys are arguing about at this point... The Vertigo manual specs ATF fluid. I'm fine with that. Edited March 9, 20179 yr by heffergm

I actually asked the same question of LS of why Maxima 0-10W ? I would agree the Mobil 1 ATF is a good substitute.

March 9, 20179 yr Author Yeah, none of those are Transmax Z though I've looked at the spec sheets of almost all those that seem relevant (Dexron III stuff), and the M1 is still a closer match on all the published numbers. Edited March 9, 20179 yr by heffergm

Yes It can cope with high pressure but gives good frictional properties reference organic friction material to give smooth take up in clutch packs.
