jjb7 - can you elaborate on why you say it is almost impossible to overfill a Tiptronic? Not calling you out, I'd just like to know why or how you arrived at that conclusion. Thanks -

JFP - gonna mark this 'solved' for now. I have a few more things to do on the car before taking off the jack stands. I had a feeling prior to doing the filter/fluid that the car was a bit low just by the way shifted when i used 1st gear and guess i shouldn't be surprised by the 'extra' ~1.5 liters. I really appreciate the help and comments. serbox, thanks for chiming in, too.

OK - so, just got it to temp and added a 6th liter of ATF. There was no overflow so I think i need to add more. Anyway, I ran it through the gears and noticed both axles turning and no noise (clicking) when I put it in park. As i noted in my 1st post, i have had no problems with the tip. in this car, even had it out for a DE. Is it really possible that i'm a liter or more low? Oh, axles still 'free' to rotate even when in park.

Roughly 36/37 Celsius.

Thanks for the reply JFP. To provide a lengthy reply to your question - After the initial fill (3.5 liters before overflow) I ran the car to temp and checked. At temp I added almost another liter before it overflowed (this is when i didn't notice axles turning, and had the clicking noise). Despite those issues I ran through the gears again and re-checked and added the remaining AFT from the 5 liter bottle (it didn't overflow this time but I was out of ATF). I was very surprised that i needed more than 5 liters ATF and also worried that I mucked up the trans. so I measured the quantity of ATF I removed and it more/less filled the 5 quart bottle to the same level. I am going to get another liter of ATF and re-check the level today. Also, I tried turning the axle by hand and noticed that with the car in park I can freely rotate them in both directions. I thought they would be 'locked' into place when in park. Any thoughts? Thanks again.

Hi - this is my first post so I'm hoping someone can point me in the right direction. I tried search (google) but think my search skills stink or really can find an answer so forgive me if this has been asked!! The Car: 97 Boxster with Tiptronic, 89k miles. The IMS, RMS, water pump were replaced when i bought the car. I've owned the car about a year and have no idea when the tranny fluid filter was done.(no tiptronic problems). The Problem: Today I decided to performed the trans. fluid / filter change. I followed the technical article posted on Pelican and didn't have any problems until it came time to run the car through the gears. When it came time to shift (R, 1st, 2nd, etc.) I was expecting the rear axles to turn and they didn't. So, that didn't bother me too much until it went to put the car in park. When i did i got a very audible clicking sound coming from what i assume was the transmission. It eventually stopped (as if the transmission stopped turning) but now i'm worried something is broken. Some notes: The old fluid looked very similar to what you seen in the pelican article (blackish) When i drained the transmission i recovered +/- 5 quarts of fluid when i expected roughly 3.5.I replaced all 5 with Pentosin ATF 1 Not much 'sludge' in the pan or accumulation around the magnets. nothing smelled burnt. Could this be a simple shifter linkage problem? (all the gear indicator lights seem to light up properly when i shift/select manual mode) Does it need MORE ATF ?(I'd like to add more ATF (if it needs it) but am terrified that if i try this procedure again I'll wreck the trans (if it isn't already).) One last question - when the transmission is in park, should i be able to turn the axles? If anyone can help a noob I'd appreciate it. :thumbup: Thanks! joe
