What is this magic tool?

It is a nonsense to have to drop the sump to change the filter - a simple change of design at the development stage could have a horizontal slot at the 1/3 back from the front of the sump that the flat filter could be slotted in and removed when needed.

I removed 4.7 litres of old oil in put in 5 litres. The sump cold took 3 litres through the filler hole and I pumped the other 2 litres into the transmission cooler.

Drives fine as it did before but seems to hang onto 3rd a little longer - I guess it will take a little time to adapt. The car needs a service in 2500km so I will do another basic drop of fluid then and refill when hot between 35 and 50 degrees.

In future I will suck out 1 litre each 20,000km and top up with a fresh 1 litre as my ongoing service regime.

Cheers

The vast majority of auto trans use an in sump filter - there are a few around that use an external canister type filter from the factory but its not very common. Most of the in sump filters are fairly average too - more like strainers to keep the big particles out

Garry, I will be doing my service in the next couple of weeks, I will take photos for you [emoji6]

Yes please just interested. It easy to put the front bolts back in once the threads have started but is hard to do that. If able to hold the bolt in place I actually found it easiest to start the bolt was to use a long handled blade screw driver at an angle until the treads take hold then use the torx bit etc to do it up. The position of the roll bar is what causes the issue - stopping piggy fingers getting in to hold the bolts in place.

Hey rar110 - i live not far from Gregs workshop and just about to sign off on a D3. Are you happy with the work Greg and his team do?

Thanks

Hi Matt
Yes very happy. I’ve been going there for about 4 years. He’s an enthusiast which helps I think. He does quite a bit of work on D3s.

But be warned he gets a lot of work in his workshop. If you drive past you will see a lot of cars outside waiting for attention. If you absolutely need the car back the same day then let him know when making the booking.

His workshop is close to the train station which is handy for me.

Good luck with the purchase.

Regards Peter

Picked up my MY09 D3 yesterday and its booked in with Greg on Friday for a general check over (needs brake pads). Its got a got a good service history 235K on the ODO paid $14,500 its neat. Been watching all the videos i can about sell servicing (within reason). Happy with it, had been looking for a D2 but the universe had other ideas.

Tdv6 or v6? Either way you did pretty well.

Maybe consider a trans service. This era 6HP26 has the lead free stator bush.
