Tranny = Dexron III
Rearend = Gear oil (80 or 90w not sure) + 1 tube of limited slip additive

axle- redline 80W-90 or royal purple 75W-150. FWIW, the royal purple thick stuff reduced the gear noise a bit in my other M6 car.

Transmission- valvoline dexron III in the stock transmission, motorcraft type F in the Yank tranny. (He specifically said to use that so I did.)

GM calls for synthetic fluid in the rear axle + 1 bottle additive.

Normal Dexron III in the tranny is fine. Rather than buy expensive oils, change the fluid more often.
