3.5 litres for gearbox and 1.5 litres for rear diff. Those are the only changes you need to do.

Same as above. make sure you use the right grade oils. Some oils do these box's real damage if not up to the job.

i use silkolene pro s for engine so what would you say about gear and diff oil?

Call Opie Oils and ask them as they know everythingand maor about everyapplicaion you could think of.

Stick with Millers CRX 75w 90nt (nano technology) good stuff and perfect for the job. If you're going on track or drag days I'd consider 75w 140 but it's not needed for road use.

Einstein has suggested exactly what I would, one 5L container is ideal to do the lot. Gulf Competition is another to consider and a little cheaper.

Did a bit of research on this and if you have dccd, then you need something like motul 90pa for the rear diff because it has friction modifiers in it or something which is needed for the ls rear diff, and motul gear 300 for your dccd box.

CRX 75w 90NT contains friction modifiers which are fine for the LSD. This oil can be used both in the gearbox AND rear diff, no need to be buying separate oils.
