Thread: Another Disco 4 Torque Converter Shudder

You will probably have to get somewhere to order it in for you. I think Repco used to stock and may be able to order in if they don’t have. Or try calling MJ Products in Hallam and see if they can send to somewhere you can collect from.

You can also download the AusPost App, and set up a Parcel Collection delivery address at one of 3600 locations around Australia if you know where you will be. This will give you a unique delivery address you can then use when ordering on-line. Parcel Collect gives you 10 days to pick up, whereas Parcel Lockers have to be collected in 48hrs.

Collect your parcel from a Post Office - Australia Post

The only catch with Parcel Collect is just make sure it isn’t letter size or too large (see the FAQ for what can and can’t be posted).

Some eBay sellers also offer “Click & Collect” at Pharmacies and other retail outlets across Australia. These have to be collected within 7 days. Filter by “Click & Collect” when searching and then nominate a suitable delivery address near where you plan to be when ordering.

Thanks for the postage info, if we need to get it. Will set up Aust post and stay a bit longer somewhere

Now not to stress you out…..much….

Don’t live with the shudder for any longer than you have to.

There is anecdotal evidence that transmission shudder can contribute to snapped cranks on the 3.0TDV6 (I admit this is pure speculation by some but seems to be more prevalent with the 6 speed 3.0’s).

Left Myall shores and drove to Sydney about 250k
We felt shudder in all gears when leaving a servo and accelerating to merge on the highway.
After that I selected Command shift and drove the rest of the way selecting the gears and no shudder at all. Even with some steep hill starts.
I have a Gap tool and no error codes, car thinks everything is normal.

Is it ok to only drive in Command shift?

I have ordered some Lubegard shudder fix, will collect it in Melbourne, can I remove the transmission line to the radiator, drain out some fluid and replace it with Lubeguard?

What I don’t get, research says shuddering is caused by contaminated old fluid and it can be solved by a mega flush.

We towed the van back from Winton to the Gold Coast to get the transmission serviced, no shudder, now the transmission is serviced with fresh fluid and we get shudder.

I will do a Mega flush when we are home and see if that fixes it, if not a Tc rebuild

No need to remove any fluid as you are only adding about 50ml or so. A flush wont fix it as its caused by glazed and failing clutch friction material in the converter, dr tranny is only a bandaid but some people report it buying them a few more years.
No issue using command, youre doing it a favour by shifting early instead of letting it slip.

Thanks for the info, will use command to get to Melbourne, then some shudder fix and hope it gets us home.

FWIW, the ones I have seen that had the TC shudder shortly after a "transmission service" have had something other than genuine ZF lifeguard 6 or Penrite BMV put in.

Was the service done at either a Land Rover or ZF workshop?

If the shudder fix does as it says, then most of the glaze should have been removed from the lock up clutch in the torque converter and you should then have a bit of success with a full flush, if it was only due to incorrect fluid.

If the correct fluid was used, then, as previously stated, the damage is probably already done and a replacement torque converter and valve body kit will be on the cards.

best of luck

No, the service was done by a reputable transmission specialist.
Fitted a steel pan and used ZF Lifeguard 6 on the receipt.
