Hello:

I did the search and only see people are changing Transmission Fluid. I was wondering whether the Differential Fluid need to change on 996 Turbo? If so, can anyone direct me to the link where I can perform this task myself.

Thanks and happy holiday!

 

Yes, the diff fluid should also be changed at the same time as the transmission. There's not much to it- use Mobil Delvac 1 full synthetic gear oil- 75w90 weight.

 

There are a few DIYs on RennTech to get you through these jobs. The transmission one is here, the Diff is close by.

Thank you very much for the suggestion. I just ordered the oil "Devac" and should perform the task this coming weekend.

Happy Holiday!!

 

how often do these need to be changed?
