Cayenne GTS Manual Transmission help

[jamiepstewart]

I wonder if anyone reads these....  I am hopeful.   :)

 

I have a 2008 Cayenne GTS with an awesome manual transmission.  I can not find much of anything on when to replace the transmission fluid... nor how to replace the fluid.  I am quite familiar with the automatic transmission fluid change (in my previous CTTS), there is next to no documentation on the manual GTS.  

 

I have searched google and the forums for some answer or clue.... nadda.  So any help would be greatly appreciated.

I have the same problem and just started a new thread.  I searched and say no one responded.

Hi CaptJim...  I have not found an answer to this yet.  My assumption is to replace the fluid, it is the same as other manual transmissions; drain from the bottom and top it off through the fill plug.  I may buy a service manual for this answer (and many others).  If you find anything, please let me know.

[CaptJim]

Where is the fill plug, that is the problem, it is not obvious like most manual transmissions.  Plus, no socket will fit up in there.

Drain = orange arrow

Fill = green arrow

I have removed your duplicate message.

Thanks Loren.... Just as I suspected. Very straight forward.  Now the next big question...which Tranny fluid to use... :) 

[CaptJim]

Look at that, its on the passenger side.  I will crawl in from the other side and locate this, Thanks!

And now, for the $1M question.....  What fluid is best for this transmission?

The Reenlist site likes the royal purple synchromax.  I hear good things about the shifting quality.  I am going to try it as I could use some more equality in my shifting.....

I would love to hear the opinion of others on the Transmission fluid to use.  I am partially inclined to keep it OE... but with higher mileage, it may make sense to use a 'pure grade' synthetic rather than Mobil 1 - such as Swepco?  Redline?  Please feel free to add any suggestions.

I use Mobil Delvac 75W-90 in my other cars gearboxes with good results.  I'm considering this route provided all the API grades agree.

I think that is a good choice.

 

Everyone please be aware this thread is about MANUAL transmission Cayenne GTS. Not many of those in the US/Canada area.

Thanks Loren.  Glad to have a second opinion.

 

I'm coming up on this service being needed so the timing is perfect.
