It's not that difficult, just take your time, if you have some ramps like at a workshop or something then it's really easy!
My trans finally blew on the way home, luckily I managed to limp it back to my girlfriends house! As soon as I took it out of drive it would stay permanently in park even when cooled down, these cars are seriously heavy to be pushing around!
I ended up pulling the pan and mechatronics in the parking space.
Here are some pics:
Pan and mechatronics removed
Mechatronics in the kitchen!
This was the cause of all the problems, this is almost certainly what's wrong with yours.
This is the valve body with the electronics module removed, notice the grey film? This is debris from the clutch packs, it's conductive and can cause issues with the speed sensors. It's worth cleaning as much of this off as possible.
Makeshift shelter! It was raining!
New seal fitted
My mate helping me refit it!
The seal itself costs around £5! A cheap fix to an otherwise very expensive transmission problem!
I have heard this and the connector sleeve an leaking oil pan are the three most common problems, a local ZF specialist has confirmed these boxes come back for repair and these are the issues they all have, very rarely does anything mechanical go wrong with them. The mechatronics is pretty intelligent and will go into failsafe immediately if something is wrong to avoid causing internal damage. It may be a nuisance but at least it's not wrecking itself!
Hope this helps, any questions just ask.
