hypoid API GL-5 for the rear end(recommended viscosities SAE 85w-90 or straight 90)

Some people use MTF/MTL (SAE 80) in the manual trasmission,which is close to ATF ,or engine oil...
There is a confusion on oil for 1981-on transmissions,as MB specifies 80W oil(made by Exxon-Mobil, Esso Gear oil MB 317 and sold at the dealer at twice the price)...MB 235.10
Another strange thing is that nowadays MB docs specify the obsolete ATF TASA than Dexron fluids....
