Quick update, RE: The gearbox service @ ZF today.
As per usual Nico & Hardus from ZF made me feel right at home. We had a lengthy discussion around pretty much everything around the 6HP autobox, I felt like a kid in a candy-shop asking a billion questions about adaption values, box longevity, torque converters, clutches, why are there 5 Land Rover Discoveries at the workshop (by the way dont buy a Discovery), when should I change my diff oil etc etc.
The oil on the gearbox cover turned out to be a combination of factors. I was told the sump and some other plastic components get brittle after years and years of heating up and cooling down. This causes some sweat, and although not a majour issue, it should be tended too. In the end all old parts where replaced, including the sump and I was in and out in 2 hours.
Pics of the before, sump clearly leaking
These are the plastic pipes that where sweating
Most of my preventative maintenance has come to an end unfortunately. I might have some cosmetic updates in due time, thats all folks! :cthulhu:
