...engine running cold transmission just undo filler plug and quickly squirt it in. Filler plug in and go for a drive.

Engine and transmission should be warm. That gets the level down. I drive mine up a large Boulder on my property which is the same as jacking the front right corner up high. You want the fluid to run back and the the left of the car. If you do this you can take the plug out without losing fluid. The product comes with a "tip" you poke in and squirt away.

First time I used it was on an 05 model 195000km and within 3km the shudder was 100% gone. Like new. 2 tubes.

My auto seems to have developed a whine in the the lower gears. Most noticeable 2nd gear on overrun. Also in the last two days it seems to get stuck in what feels like 3rd at the first intersection I stop at. After that it's all good. Any ideas

Well I've decided to cut short my holiday due to the auto noise - we where planning to camp on the beach which would have involved dragging our camper trailer through the sand so didn't want to risk overloading it and having a big failure in an awkward spot. Trans got stuck in 6th this morning at a roundabout so didnt pull away real quick. Big F on dash with limited gears available. P0730 fault code recorded. A restart sorted it for now, but need to get home first (300km away).quick check of oil level and that's OK. Next issue will be to get it down to perth to have it looked at. Any recommendations for repairers in perth?

Sorry to hear about your troubles. I've spoken to a couple of guys and had them go for a ride in mine trying to find the cause of a 'shudder' in 3rd. From my experience I'd see Drew at Automatic Transmissions R Us in Balcatta. I was impressed because it seems mine is not the usual 'death shudder' and may not be transmission related at all, Drew sent me off to check some of the logged fault codes related to miss fueling (IIRC- Getting them looked at next service) when he could have, at a minimum, got me in for a tranny service. Further he seems very knowledgeable on the ZF unit.


Anyway that's my two cents worth. Hope it gets you home without further trouble.

spoke to Kevin at Rover Tech. He suggested checking out the transfer case ECU as that can cause auto issues. So I've pulled the ECU and there is a little corrosion around the pins - one pin appears loose. I can understand how this could affect the trans shifting, cant figure out the mechanical sound Im hearing however. Got home ok, but now gotta look at getting it a further 1400km to perth to get someone decent to look at it (mechanics here just seem keen to throw land rover insults at you because its not a toyota)

Well, was going to run the gauntlet and get the disco to Perth to have it looked at, but the auto had other ideas and appears to have crapped itself completely. So its onto a backload from Tom Price to Perth as we speak to get looked at down there.
