Yes you can, you can remove the under tray and framework to hold it leaving just the sump to come off, then drain it out, refill, run to temp and top up, then go for a drive etc and drop the sump off next time.

There is a note to say that on these the initial temp should be up higher to open the thermostat, I didn't do that so only got 5 litres out. However in theory if you run it unto about 70 deg the stat should be open and you will get more oil out.

The problem is on a short drive you won't necessarily get the temp up enough to open the stat. so worth letting it get a bit hotter maybe and you may get more out the second time.

tbh, topping just 5 out has made a decent difference.  There is nothing that can't be fixed with a hammer😜😜

Thx Mark.

Mine's double the mileage of yours so needs as much fluid changed as poss.

I'll do the 2 x 5 litre changes - ordered 10 litres and a sump. Geez the price has gone up since COB posted, his price was £130 for 10 litres, now £187. That's one hell of a price jump!

All in I think it's £235.

From reading people's reports on a machine flush, seems like that would be £400-£450. I'll be able to do at least one of the changes on a ramp so figured I'd make use of the ramp availability and go for it.

I've no overheat messages, but it's not silky coming on or off the throttle on a manually selected low gear.
I watched Edd China do the Boxster they bought for a grand with a dodgy tiptronic box and a fluid change was all it needed. So pretty sure changing fluid will bring back my ZF silk!

. Cheers, Greg

2011 Vogue SE 4.4 with lots of toys in Stornaway

Just did the filter and oil change on mine this afternoon as it had started to feel just a little harsh. (90,000 miles). Very similar to when I did it on my BMW 740 with the ZF5 speed, you could feel the transmission just getting a little less silky.

Change done, no probs really used the ZF kit which I bought from buycarparts https://www.buycarparts.co.uk/zf-getriebe/8824048 takes about a week to get here as shipped from Germany.

Took out just over 3.5l, oil wasn't filthy but darkish and the sump/magnets had a small amount of sludge, nowhere near as bad as the 740 was though although that was done at 120000 miles.

I used one of the Lidl oil pumps to push the fluid in which made it real easy, no real issues apart from I couldn't figure out why I wasn't getting more than 2l back in after starting, doing the shifts up and down box etc. Then remembered I needed to have the engine running to top up

Once I did that got a total of about 3.75l back in.

Immediate difference in driving, the shifts are back to seamless and almost imperceptible even when using the paddles to manually shift down. You forget how smooth these boxes are until you do something like this

Cheers,

Glad yours is back to silky MM.

Mine - well I did three changes back to back (with drive and up to temp between) - hoped for silky but sadly no change to a bit of minor thunk when off and straight back on the throttle say second gear. Kick down is a bit thump too.

Higher gears, higher speed all pretty smooth.

Really not sure how to diagnose now.

I've since seen a 'service kit' for the 8HP70 which includes a few seals, o-rings etc. Maybe I should have done that... Or something to do with the mechatronic?

Any suggestions most welcome!

Thank you for the car parts link

Opie want more than 400 quid for what looks to me like the same kit
Maybe I am mistaken

I've bought stuff from buycarparts.co.uk and they are always a lot cheaper.
So it's probably the same stuff.

Changed the oil in my 8 speed box at 123k miles, here is what I found.

The oil appeared dark but still has a green colour and smell like oil, not burnt.

If you put it on a dipstick (now antique curiosity’s) it looks quite clean.

Here is the original oil on an improvised dipstick.

that's a good illustration of how clean you can get the oil after 2 changes.

pretty much removes the argument for flushing the box imho. the second change oil looks as close to the bottle as you could hope for  There is nothing that can't be fixed with a hammer😜😜

Where is the filler for the tranny oil please?

The whole of the sump pan is the filter, and is replaced...
An example....

I know, but I want to check/top up mine.

Old thread i know. I recently purchased a 2012 TDV8 4.4 so the 8 speed box. 110k on the clock and no evidence of the box being serviced. so having been burnt on my 2004 TD6!! i am going to do the box.

my plan is purchase 10l oil and new filter
drain the oil and re-fill leaving the old filter in place
run the car down the road and back let cool
drop the oil again this time replace filter
refill and consider it serviced

this way i should get most of the old stuff out and save my self a few hundred quid by not having a full flush

I'd just get it Megaflushed on your drive by Ian Bodsworth and save yourself the hassle and know 100% oil has been changed in one go. I've had it done and I can vouch for his service, professionalism and knowledge  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Did the same as you on both my TDV8 & SDV8 and was happy with both results
