TIP Fluid Mobil 1 Synthetic

[racerden]

For a 2003 996, everything I've read says Mobil 1 synthetic ATF is more than compatable w/the required ATF 3353. Your thoughts/experience in the synthetic ATF arena is greatly appreciated.

Thanks,

Just a little off topic here, hope you don't mind. For a '98 996 with the ZF tiptronic, is there a separate gear oil for the differential? Or does it share the oil with the ATF (I hope not) ? Is there a DIY prosedure somewhere on the Forum? And what is the gear oil spec? 75W-90 GL5?

Is this the same case for the newer version Tiptronic (MB based transmission) as well (apart from the difference in ATF type used)?

Haven't seen this topic being posted before, so I thought I should ask.

Thanks in advance.

The differential part of the Tiptronic use a manual gearbox/differential oil, 75w-90 should be fine, so certainly do not use ATF for the differential part. Only the older Tiptronic have a drain plug, you can suck out the old oil using the filler plug in case you decide to service the differential oil on a younger type.

Thank yoiu RFM, for the info. I'll look out for the differential drain plug when I do my ATF fluid change. I guess its location is obvious when I'm there?

Drain and fill plug for the differential are located on the right side of the unit.
