How Much Gearbox Oil

[wannabe]

Hey All,

I have been reading heaps of threads about chnaging the gearbox oil in an R33 Skyline. Some posts say it requires just under 4 litres and other posts specify that it requires 2.8litres.

It seems like a fairly large discrepancy to me.

Can anyone shed some light on what the correct amount of oil for the gearbox is for me?

Thanks

depending how long you let it drain for is how much you put back in.you put in as much as it will take (until it drains back out the fill hole). Buy 4 litres to be safe. mine took about 3.4litres its a manual R33 gtst

Yep... buy the 1gallon bottle and a 1lt bottle as well, just in case (you can always return the 1L). I just put 3L in my R33 Manual gearbox, but i don't think it was completely drained (mechanic said i needed to top it up after the removed it due to spillage)

GEAR OIL CAPACITIES

================

RB25DET is 2.8 litres to the drop. I measured it to the mL, squirted it into the box and a single teardrop flowed out the hole.

RB25DE is 2.5 litres

RB20E is 2.0 litres

4WD RB25DE is 4.1 litres.

DIFF OIL CAPACITIES

===============

RB20E non LSD is 1.0 litres

Active LSD is 1.6 litres

All other R33 2WD types are 1.3 litres (90% of ECR33 diffs)

Non GTR 4WD types: front is 1.0 litres, rear is 1.3 litres.

=======================================

AUTO TRANS CAPACITIES

==================

5 speed is 8.5 litres

4 SPD 2WD: RB20E is 7.9 litres; RB25DET is 8.3 litres

4 SPD 4WD: RB25DE is 8.3 litres

=======================

Hope that provides some clarity !
