A few months ago I drained my 997S tiptronic gearbox, 6 quarts came out and was able to put back just 3 quarts using the very stupid procedure of running the car for 30 minutes, shifting through gears, opening a small stupid little fill plug, and pump in a teaspoon each time.... and then managed to round off the allen fill plug. I know there must be a different way.
Then I got to thinking! These are German engineers. The factory assembly worker would never put up with that inaccurate, time consuming stupid fill procedure. There must be a better factory way or they would fire the design engineer.
After yanking out engines on a 997TT and a 996 with Tipt, I noticed a 2 inch round cap at the front tip of the gear box and knew right away that this is how the factory filled the tipt gear box.
So, this weekend while I was changing out the 997 water pump, I took the opportunity to drain the coolant, removed a couple of S hoses, and lower the transmission nose by about 2 inches. I reached up to find the black cap, snapped it off with a screw driver, and ... found the fill port.
I used a right angle fitting, attach a hose to one end, stuff the other end into the fill port, and stuff up some rags between the body and the fill por to keep the fitting in the gearbox
Use a hand pump, suck up the fluid, attach the end of the pump to the hose, and pump the fluid in. After 5 minute, I was able to put in another 3 quarts of oil.
Hah, take that you stupid Tiptronic engineer who expected us to sit under the hot running engine and fill up one teaspoon at a time. Eff You.
The picture shows the front of the gear box, and the circle is the fill port with the cap snapped off.
