I have changed it and only got just under 4 litres out so that's what I've put back in. I just don't want a leaky or broken box. Thanks for any help.

Including just leaking in general and blowing seal out from heat expansion?

Nearly everyone runs 4.8l with no issues. Give malwoods a call and he will give the best advise.

Rather ask the question than just go along blindly. Thanks mate.

gaz097 Bronze Donating Members 1,752 Member For: 13y 9m 12d Posted 02/05/15 11:52 AM Share Posted 02/05/15 11:52 AM I went from 30k old dex to 70/75 and it improved the noise probably 10%. The shifts are not great when cold(maybe a little worse then dex but not unbearable), but are definitely better when hot and shifting under load. If I was at stock-300kw I recon it would shift super quick. Trying to push 460kw and a butt load of torque threw it is slowing it down at the moment.

It does feel better with the new oil. Happy I did it. The original dex was 25000 old so small difference but always happy when things go smooth and actually do what you intended.

Much better. Link to comment https://www.fordxr6turbo.com/forum/topic/90456-fg-manual-box-oil/#findComment-1654829 Share on other sites More sharing options...
