Perhaps this kit? They used this one on mine:

ZF6HP19 Fluid Filter Change Kit - Bristol Transmissions Ltd

They used the pentasin fluid on mine and no problems



ZF Lifeguard 6, Shell M 1375.4,Transmission Fluid, ATF,

Which oil they used?

There own oil. Doesnt have a number or a name, buts they said its pretty much the same as ZF lifeguard 6.

Hi guys, I may be trying to wake up a dead thread, but I've found a interesting web page with what looks like exact description of the OP original problem.

AGCO Automotive Repair Service - Baton Rouge, LA - Detailed Auto Topics - What is Torque Converter Shudder

Here the vibrations are reported as torque converter shudder with a very detailed description of possible cause and way to fix it. Worth reading.
Interesting point is re-tightening the valve body bolts while doing the ATF change.
I may give it a go, i.e. ask my indie to re-tighten the valve body when doing the next ATF change. As OP's car, mine had developed the same kind of shudder which was mended by ATF change. However, the shudder eventually came back after about 7-8000miles, not as bad as it used to be, so next ATF change is on the cards, this time with re-tightening the valve body bolts and replacing the ATF cooler pipes due to surface corrosion (just in case).

Have a look at the web, see what you think.

Mine's had a fluid/filter change at 86k miles and is having another fluid change in few months, any idea what the torque settings should be?

I am just checking ElsaWin copy on my computer, so give me few minutes.

Here you are Mark:

Tighten securing bolts -1- and -2- for mechatronic unit to 2 Nm.

–	Then tighten retaining bolts to 8 Nm in specified sequence -1 ... 11-.

That's what ElsaWin says about my car (A6 Avant LeMans, 3.0TDI, 2008).

I've had to remove the ESLAWin image from the above post.

If you must share it, please do so off the forum. Petty I know, but I quite like VWAF and I want it to remain open and free for all.

Appreciated Fun, pretty low torque then!

Am guessing it's easy to access once tranny sump dropped?

[funavant]

Mark, it should be accessible right after you drop the sump and remove the strainer.
Sorry about the picture had to be removed,if you need it, PM me and I'll send it to you.
I would just ask the guy working on my tranny to set the torque to 8Nm and go round the bolts and see what happens, if the bolts would turn at all. The idea is that the gasket perishes over time and may get thinner compared to when new, therefore not sealing properly and causing cross leak. If you think about it, it does make sense because when there is a small cross leak the tranny cannot apply enough pressure to the lock up clutch (when in low rpm) and that's where you can feel shudder.
So re-tightening should make the mechatronic (valvebody) unit to sit tightly, preventing cross leak and allow to build up enough pressure for the lock up clutch.

Hi all,

Is it actually possible to do this job without raising the car on a lift? My Car a May 2005 3.0TDI Quattro tip avant, seems to be too low to get underneath it!
