    P38 ZF Auto oil spec/brand

    Time for Auto trans oil & filter, spec is dextron 3, just wondering if there are any preferences or if there is a synthetic for this,

    cheers

    I use Fuchs 4400 , but you could also use penrite ATF/ fs, both are miscible with standard dex3 as you'll only get around 5 litres of the 9.5 litres total out with a standard oil / filter change.

    I use Castrol transmax Z in my D2 and also used it in my RRC 91. My RRC auto was excellent at 240KK and my D2 is excellent at 190KK..

    Transmax Z is approved by ZF and recommended for use in heavy duty applications.

    It is expensive at $95 approx. for 4 litres, but hey a lot cheaper than a rebuild.

    I wouldn't bother if the car has been neglected over a high mileage as autos are dying from the day they first turn.

    Supercheap no longer stock it but Repco does and you can sometimes get it 30% off.

    I was told by the castrol rep in Bendigo that ZF doesn't recommend synthetic as it can strip the glue that holds the bands on - it certainly seems a credible source.

    I've always used their ATF dex3.

    Well the rep was wrong.
    Have a look at the ZF approved fluids list published by ZF and you will see Castrol Transmax Z which is a synthetic.
    Regards Philip A

    ATF for ZF automatic transmissions
    or from ZF themselves

    That's interesting ... Nulon only list full syn for ZF ZF - Nulon Products Australia

    It may be the ZF 6, 8 and 9 speed Automatic Transmissions ... which have the problem

    I have emailed Penrite for their suggestions
