Tim I made the recommendation on behalf of the VOC which stands at 100,000
miles if using the correct fully synthetic ATF for the AW30-40 and AW30-43
gearboxes fitted to 960/90 series cars. Also for The Europe market 2.5 Litre
models with M90 gearbox (manual) which also uses fully synthetic ATF.
All the best, Peter.
