Thread: I'd like to understand the D4 tranny??

Hi Scott, new pan (plastic) and filter and 9 litres of Lifeguard 8. I priced the parts from a local supplier and was intending to do it myself, but the car was going in for the 52k service anyway and they quoted $50 more so I decided to get them to do it, why would I bother for $50 and it's now vehicle service log.

Regards

If you can please let me know as my MY14 has done 70,000km and I want to change the oil at the next service.

Just wondered what the motivating factor was for a steel pan. Engineering plastics posess some excellent properties these days and in many measurable ways can out perform more traditional (steel) materials. If you are doing serious off road stuff I would contend the steel pan would offer little additional protection over the standard pan and my money would go toward a proper full length guard.

Just my 2 cents..............Peter

My understanding is that the filter is integral with the OEM plastic pan which requires significant work including lifting the engine on its mounts to remove it to do a filter change. The steel pan conversion includes the filter as a separate item so a oil and filter change is possible without having to remove the pan itself.

Nothing to do with durability. Purely to do with economics of doing filter changes on an ongoing basis.

You still need to remove the pan to change the filter - it's just a heap easier to do with the steel pan. At least it is with the 6 speed, I'm sure the 8 speed isn't any different in that regard

Thanks, that's quite an explanation about how the box works. Whenever I tow, I have the gearbox temperature shown on my Gap tool & also noticed that the temperature sits in the 90's even on long climbs.
