Transmission oil pan leaking?

Recommended Posts

Doing my usual Saturday morning check-under-the-car routine, and noticed that something might have been seeping/leaking very slowly.  I was investigating what could be making the noise referred to in this http://www.renntech.org/forums/topic/44468-auto-noise-when-stationary-and-in-gear/

 

Nothing on the ground.

Did the most sensible thing, and pulled the cover off, and cleaned it up (pic below)

Checking around, it seemed that the area around the transmission oil pan is a bit grimy, like being caused by slowly escaping oil.

Interestingly, one of the bolt's head was filled with oil.

Definitely not engine oil, so would it be that the pan's gasket is leaking, or the pan hasn't been tightened correctly causing it to seep oil?

Or is it something else?

Car is 2003 C4 Cabriolet Tip

Maybe after cleanup, just leave the cover off and drive it for a few days and recheck to see exactly where the oil is sipping from?

Sounds like gasket. Can also use a torque wrench to check the bolts.

Thanks Ahsai.

 

Gasket was my the top of my list, they might not tightened the pan correctly as suggested by Porsche when they took the tranmission out. 

 

BTW, would you have any idea what would be causing this sound, as captured in my last post in this thread http://www.renntech.org/forums/topic/44468-auto-noise-when-stationary-and-in-gear/?p=261472?

      My 2001 C4 Automatic had what appeared to slip (over rev) when making scarp turns, decided to replace transmission filter and refill, the first run after 10 minuets the transmission went into limp mode (lights on drive selector started to flash) check engine lamp came on (P0734 and P0734) was read. the reason given was input and output ratio wrong for both codes.
      The Durmatic gave no other info. So I proceeded to  order both input and output sensors. Since I couldn't confirm if a shift selonod was bad. Mean while I am in Cal for the holidays I remembered I moved two of the magnets in the pan there were 4 magnets 2 each in the depressions in the rear of the pan I took one each and moved the forward closer to the input and output sensors.
      Anybody out there have any idea besides taking it to the dealer, at 75 bucks for the 5 liters of tranny oil each time I replace something to help me be smarter?

      Hi all,
      After 18yrs my convertible top has finally encountered its first issue.  After using this forum (thank you!!) to figure out how to access all of the components (top was stuck in closed position), I found the root of my issue, a bad cable.  However, as I was very carefully removing the cable from the transmission, the "clip" which is molded into the plastic cover cracked and is no longer functional (see image).  Not really surprising on an 18yr old piece of plastic.  The transmission works perfectly and I do not want to replace it, so I am looking for advice on any other ways that I can keep the cable properly engaged to the transmission.  Please let me know if anyone else has encountered this and if there are any viable solutions.  Thank you!

      My 2011 Cayenne S has possible sunroof drain leaks.  I wanna remove the headliner and address the tubes.  Any instructions on taking down the headliner?  FYI,  I have cleaned out the drains in the wheel arches.  Also drained the water in the frame under the sills.  No more sloshing sound.
       
      Thanks.

      I recently changed my transmission with a used one I bought online. 
       
      After picking up from the shop which was about 2 hours away the truck drove fine while on highway but once i got off the highway and came to a stop the truck wouldn't accelerate. I hit the gas and for about 3-5 seconds it didn't go anywhere and then all of a sudden it kicked in to gear. When i drive it with the tip-tronic it seems to be fine until I come to a a complete stop. 
       
      I read on a different forum that someone was having the same issue and got some software updated but unfortunately doesn't say what the update was and it's a post from 2013. 
       
      Any help will be greatly appreciated. I really like this car i purchased a couple months ago.
