Last week I bought 5 x 1 litre bottles of Lifeguard 6 for $29 each with NRMA discount at REPCO - they have their specials every couple of weeks so if you are not in a hurry works out well.

Alternatively you can buy 20 litre drums from ZF and this works out about $26 a litre.

The transfer case oil is completely different to LG6 - DO NOT put LG6 in your transfer case.

Paid Automatic Transmissions R Us in Balcatta $900 for full service based on 2nd time with steel pan. 173,000km (last done 89,000km) and they said everything was AOK with old oil. No detectable change in operation after the oil change.

Hey I just moved over to a D3 TDV6, from my (not so) trusty D2. I am about to have the tranny rebuilt. Could anyone let me know what other jobs I should be doing whilst the box is out? I was told the electrical connector sleeve. Anthing else? Thanks!

Did you purchase the car with a transmission problem?

Yep i actually run a used car dealership. Ive taken the d3 knowing about the transmission issue but feel the car was cheap enough to allow me to rebuild it. Got a good transmission guy here in Wollongong.

So you are allowing for 6k + for the rebuild ?

I recently purchased possibly the first d3 to enter the country 04 build 233k on the clock transmission never serviced. TC would not lock up, would not change from 2nd to 3rd or 3rd to 4th without going into fault and limp mode. Drove it home by using sport mode and manually selecting gears and using accelerator to get transmission to shift. After being told transmission rebuild by a number of people. Had Damien at Peninsula Rangie do a service flush and a few additives and transmission has recovered significantly. Change between 3rd and 4th is still a bit variable and TC is still not 100 percent but very close (neither is my 08 d3). Towed with it which helped it even more. Will do another change in 10k time to see if any more improvement.

The short of it is that I think the ZF transmission is an incredibly strong unit and that rebuilds are done when not required.

I don’t know what Damien put in the transmission all he has told me is he doesn’t use the ZF fluid and put in a number of additives. I am amazed at how well the transmission has responded.

Having owned d1, 2 x d2, 2 x d3 I have learnt not to listen to all the negatives and challenge what I am told these are great vehicles.

233000km is bang on the ‘sealed for life’ service interval
