What Oil for Manual Trans and LSD

[mgrande465]

Gday, just went to the dealer to ask what oil to use and they recommended for the trans vmx 80 and for the LSD ls 90. Does this sound right? I've done a quick google and it seems most people use the redline stuff. Just wanted some input.

Thanks.

GL5 80W-90 oil for the diff.

GL4 75W-85 for the transmission.

I have used castrol oils before and have switched to readline oils for both, didn't notice any difference.  Although I found the redline MT85, which is supposed to be made for this transmission was notchy and caused some grinding on fast gear changes into 6th.  I changed that out for MT90 and that all went away.

Factory LSD is a viscous unit, so doesn't need LSD specific oil.
