Here are steps to complete transfer case fluid change.
Used Red Line D4 fluid (about 16 bucks from ebay shipped)
Each pic is numbered in sequence of doing with step details.

Hope this helps someone here.

 

cont'd...

 

ciaka, i havent looked into as i just picked up my c, how did you determine that d4 was the correct fluid?

nice write up btw, should make it a cinch for those less mechanically inclined...

 

thanks for sharing
very important as ciaka pointed out that loosing the fill screw first before draining. just in case the fill hole is stuck.

 

Although several fluids can be used, all of which satsfy the Porsche requirements, i chose to go with a fluid chosen by anotber member (on here and renntech), who has gone into trouble of fluid comparison, and confifmed by others as well.
this product actually exceeds the needs but you can choose something else if you do not trust it. Thanks.

 

nice write up, I've been thinking about doing this. thanks.

 

i just wanted some background (trust but verify). Redline makes great products, i use them at times. Saves me the trouble of research

 

one quart does the trick?

 

Service manual calls for .75 Qt I believe, but since some is spilled due to fill process, you will use close to 1Qt. I used almost all.

 

always great to have members contribute DIY to save us all money to get more tires


great DIY!!

 

Lol...and we all know we need money for more tires...these cayenne suckers devour them pretty quick.

Nice DIY! What is the recommended interval for the transfer case oil change?

 

I do not know the service interval for transfer case, but since it is easy and cheap to do, I will likely do this every couple years. Will do same for rear and front differentials too.
If someone knows actual service intervals for t.c, rear diff, frt diff, chime in please.

 

t-case and manual trans arent even remotely in the same ballpark. I have used rl mtl in my esprit and 00 ws6. I wasnt impressed but it also was no worse than what i drained from either...
