Re: 87tq differential fluid

["Fred Munro" <munrof@isys.ca>]

Georg;

    Your transmission should only be filled with a pure synthetic G50 Audi
oil or equivalent. The rear differential can by filled with a 75W90 GL5 dino
or synthetic oil. The dino oils get a lot more viscous in the cold than the
synthetics and if used in the tranny will cause stiff shifting until they
warm up.
    The Audi engineers know their equipment and the design parameters - if
you second guess their specifications you are always taking a chance that
you will get it wrong.
