I just completed a transmission flush on my 991.1 GT3 Cup. Manual states to put in 3 liters, which I did (nothing spilled, and got as much as I could out of each bottle). I was expecting trans fluid it to start dripping out the fill hole when it reached the 3-liter mark, but it didn't.... I double checked the instructions, and they definitely state 3 liters... Anyone out there know if it is expected to start dripping out the fill hole at 3 liters, or do you just put in the 3 liters and 'trust' that your good? With my 997.2 Turbo S (PDK), you fill it until it dribbles out, so I was expecting something similar... Thx!

It will not come close to running out of the fill hole. You did it correctly, put in the 3l and leave it. We have made dip sticks to verify the level to double check and for when doing pre race inspections between oil changes but if you are certain you put in the 3l then it is ok.

 

Coryf, Thanks! I appreciate the confirmation...Being new to the 991.1 Cup I just wanted to be sure.

 

Yup. Dump, add 3 liters, done.
