What oil for Tremec TKO600

[ZR1cliff]

Any other tremec owners recommend the best oil/fluid for a new TKO600 ? It needs filling from empty, so how much do these trans normally hold.
TIA

Hasn't it got a fill level plug? I expect so and if so I'd use what Tremec suggest. It should be good at that :-)

Hello Mike, long time since i've been on here. Yes I know to fill to fill plug. Was just asking what type of fluid owners use in the UK as what they recommend in the US is hard to get hold of here. I'm seeing two types so far - Mobil 1 synthetic ATF or Dextron 111 ATF. I want to verify this.
Asking the amount was just me being lazy, instead of googling it.
