Searched around, found methods on how to do it and what gear oil to use - great. But, I'm having trouble finding the amount of oil needed to add for each subject before buying the gear oil. Redline 75w140 will be my go-to, as I am completely happy using their product for my manual transmission.

Also, I'm always open for any advice or methods you use to do maintenance on this. Thanks in advance.

 

Rear Diff - 1.2 Litres
TC - 0.55 Litres

 

Thanks DavidN,+1

 

No problem!
I just looked up the numbers as I changed the diff & the TC oil today.
TC oil looked like crap. I'm glad I did the job!
