Tiptronic Gearbox, Oil Leak - 997 Turbo
#16
Car is back in my hands. 5 hours of labour and $50 in parts, and the leak is no more. It was the connector as suspected. Thanks for the guidance!! Recommendation from Porsche was to drop the trans and potentially rebuild, which wouldn't have solved the issue and cost a ton. So glad I had a transmission specialist check it out. Appreciate everyone's help!
To anyone in Auckland NZ; if you have this issue, or any other with a tiptronic box, go to AutoTrans on New North Road. Highly recommended.

Hi,
The tip box in the 997 turbo is actually a mercedes gearbox, 722.6.
I think there is no reason it needs to be replaced unless you find copper coloured metal in the fluid.
The leak could be from the plug adapter for the cable to the TCU. Other than that look online for mercedes with the same issue and you'll probably find tons more information regarding the leak. As i said the gear box code is 722.6.

I should have mentioned here as I brought it up in a few other threads. Like someone said the box is MB so Porsche is NOT going to crack it open. I think that is the big reason they like to replace it. Keep in mind this unit if pretty bulletproof overall as the SL65 AMG cars where making pretty big power on it.
SO If someone is using this thread later on in life and you have a tip. For Tranny issues you are better off going to a MB guy. Heck the trannies themselves are cheaper bought from an MB than a porsche, IE if you destroy it, and are searching for a new one, buy an MB one.

What connector are you referring to that solved the problem?
Thank you.

what happens if you just let it be? I've changed the gasket once and still see some weeping along the edge. car is in shop to investigate dreaded coolant leak and really don't want to deal with this right now if I can help it. was thinking no big deal as long as there is no dripping/puddle on the floor

This is a common problem beyond the connector leak or pan gasket. It looks like a pan leak, but isn’t.
It’s a common problem on the transfer case,and dealer said it’s not repairable. Totally not true... a guy in NY sells the gaskets for $80.
The o-rings go bad or the bolts let loose inside. My car with 28k miles developed this leak. The internal bolts were hand tight. Use a medium grade locktite, and retorque after your first time around. The plate will snug up as you move around. Also, invest in a finger ratchet for those tight spots.

Many thanks
#nzskater: Many thanks for the tip and guidance to the local experts. I had a very similar issue (997.1 turbo tiptronic, Porsche dealer had noted leak, said it was a repeat of a pan gasket leak). Auto Trans were on to it straight away, found gasket and connector leaks, replaced connector and made their own gasket. Also replaced the front driveline connector at very short notice after finding the old one perished. Big ups. Apparently Porsche simply does not support the MB 722.6 gearbox in their own cars! Happy to help if anyone in NZ needs guidance, and very grateful to nzskater for the earlier posts.

Great to see old posts provide assistance to people, and also to see another Turbo owner in Auckland! Let me know if you're ever up for a drive. There's a long thread under the APAC regional section of Rennlist if you're interested.
