R32 Gtr Gearbox Oil Capacity?

[Moodles2]

I've read afair bit in R32 gearbox oil capacity and it seems non-GTRs take around 3.2l to 3.6l (I thought it was the exact same box as the GTR), R32 GTR Service PDF says 4.1l, whereas the few R32 GTR posts I've found have said they put in 3.5l to 3.8l, maybe even one instance of 3.4l with Redline Shockproof.

I've got a R32 GTR and I brought 3.6l of Redline Shockproof Lightweight to do the gearbox and am worried it's not enough.

R32 and R33 GTR both take exactly 1 US gallon of shockproof.

R33 GTST and R34GTT both take exactly 1 US gallon of shockproof.

From memory that = 3.8L.

Every single one I've done has taken the same amount.
