Tiptronic oil change

[Stefano Buganza]

Hello, to all,

last week, while performing a normal engine oil change, I distracted myself for a while after removal of the oil pan sump. So, my cousin, who was "helping" me, removed the tiptronic oil pan draining bolt instead of the engine oil pan one .

When I heard behind me "nice oil, very clear"...I had a thrill along my spine .

Anyway, a routine oil change turned in something much more challenging! I studied many tutorials and, at last, had the tiptronic refilled (no removal of the oil pan and gasket/filter change, as the same operation was performed just 5k km ago).

When at last I drove the car, first I had two alarms on (TC off and ABS), but I think this was because the wheels worked free for some time, but at last they turned off. Also,  tiptronic didn't shift to manual until I turned off and on the car a couple of time.

Actually, car works perfect, maybe also better than before, but I have a doubt: I followed the tutorials step by step until the first refilling, with oil pan temperature at 40-45°c, but since that moment, engine kept working for some time, so that temperature sure raised when I have done last refilling (the third one). Have I to do a final check of the level? If so, at which temperature?

Thank you!
Stefano

All topping up and checking is done at between 30 degrees C and 40 degrees C.

Thank you Loren. So, as I think to have done last topping at higher temperature, should it be better to remove the level bolt to check to drain a little or, maybe, retopping?

Best to check it at the proper temperature.

The check/fill tube on a 996 can be viewed as a temporary "overflow tube" and NEVER to be used above 40c as high temperature will cause too much fluid to "overflow".

On final topping up or checking of fluid level the trans temp must be WELL under 30c with engine running, the fluid is slightly overfilled until it is running over the overflow tube. then is allowed to drip/spill over as the temp rises the fluid EXPANDS.When temp reaches 30c NOT TO EXCEED 40c. the plug is reinstalled. I consider 30c the "FULL" mark ,and 40c the "ADD" mark. Anything under 30c will result in an overfill, and anything over 40c will result in underfill.

Clear and exhaustive, thank you! ❤
