I have found several references in the Alfa Documentation that refer to obscure grease (Retinax AX and Agip Grease 33 FD) to be placed on the main flange bearings (and other bearings and seals) when reasseambling the transmission of the GTV6/Milano.
Is this necessary? These things are immersed in oil...

I have found the Shell recommended replacement for the Retinax AX, but before buying 10 tubes of this stuff (to use a portion of 1!) I wanted to hear what others have done.
