Road tested my Boxster yesterday after re-installing it's rebuilt Tiptronic and found a differential fluid leak. It seems to be at the breather tube. The tube does have a blue fluid all over it so I am sure it is coming out of the diff and not the Tiptronic. Could this be caused by an over filled differential?

Just got my Boxster Tiptronic back from the rebuilders and unhappy with shape of the gasket. It is broken like this in 5 places. Should i change this gasket or fill the tip before installing to see if it will leak? Can i pre-fill the TC before installing as well? Also I ordered the Porsche part# 999.917.547.00 ATF and was sent Fuchs 5005. Is that approved for the ZF 5hp19?

I am removing the tip from a 2000 Boxster right now using the Bentley Manual and it has been great until the point of unbolting from engine and it is not clear on removing the selector cable from the tiptronic. Also, I think the TC gets pushed into the transmission after unbolting from Flywheel and it does do not call this step out.

Pulling the Tiptronic out of the Boxster today to ship off and have it rebuilt and it is ready to drop except the the selector cable does not want to detach from the linkage at the tip. It pulls off around the cable eyelet correct?

I ran the new fluid that I just drained out thru a coffee filter and noticed a small amount of clutch contamination and something that looked like latex, more like a thin flake of paint than anything else, but very little metal in the fluid. The fluid has no odder like burnt TF but is much blacker than I would think it should be for a double flush service. The original fluid was black with no odder as well but it had been in there for 135,000 miles. Could this "latex" looking material be Teflon? Is there a Teflon bearing in the 5hp19 and if so it maybe coming apart?

We did you refill with the Pentosin ATF-1? To my knowledge, the OEM fluid is still an ESSO product ( ATF LT 71141 fluid) and is the only one approved for 1999-2001 Tip transmissions. There are a lot of aftermarket companies claiming to have compatible fluids, but Porsche has remained very specific on both manufacturer's (Esso, Fuchs and Shell) and fluid types for these gearboxes.This was from your post above "You need to be careful about two things: First, the Tip does not like the wrong type of fluid. Specs say that the car should use OEM 999-917-545-00, Esso LT 71141, or Pentosin ATF-1." Should I order the LT71141 and try a 3rd flush? I think 75% of my problem is trying to pin point root cause. Does anyone know of a good rebuilder in the Southeast I can take the transmission or buy a rebuilt if needed? Thanks It is my understanding that the Esso product has a slightly different coefficient of friction than the ATF-1, which is why it was the original (an only) choice back in 2000-2001. If the trans does not respond to using it, then the problem is deep seated enough that the gear box has to come apart. According to ZF their ZF Lifeguard 5, which is what I used, is approved for 5hp19 transmissions including the Porsche tip. https://serviceline.zf.com/interoelepdf/TE-ML%2011_en0700.pdf 4HP20, 5HP19, 5HP19FL (1), 5HP19FLA (2), 5HP19HL (1), 5HP19HLA (2), 5HP24, 5HP24A (2) According to spare part number of vehicle manufacturer: ZF Lifeguardfluid5 (ZF No. S671 090 170) => Audi / VW Oil No. G 052162 A1 / A2 / A6 => BMW Oil No. 8322 9407807 => Citroen Oil No. Z 000169756 => Jaguar Oil No. JLM 20238 => Mercedes Benz Oil No. A 0019892203 => Peugeot Oil No. Z 000169756 => Porsche Oil No. 999.917.547.00

I dropped the pan and replaced the filter and fluid with Pentosin ATF-1 but it still slips going into 4th gear. The fluid that came out looks thick and has some metallic flakes but very little. I have the fluid to do a 2nd flush but not sure it will do any good? I found a used 2005 tiptronic out of a non-s Boxsters for $2,500 and if it is compatible with my 2000 Boxsters (non-S) I may just change it out.

I found that the communications issue with my Tip was a software compatibility issue with Durametic 6 s/w. I reloaded the Durametic 5 s/w and it is now displaying the correct temp and no fault codes, however it is still slipping. Should I replace the ZF Safeguard 5 with Pentosin ATF-1 or is it too late?

The 5HP19 tiptronic in my 2000 Boxster was working fine until I did a fluid change and then it started slipping 400 miles after the change. It works fine manually up to 3rd gear and slips going into 4th. I checked the fluid level at the 30c and it was less than 1/2 quarts low. I topped in off and it still slips. I used ZF Safeguard 5 and a filter kit I purchase from Pelican. I did a double flush on the fluid. Should I try changing back to ATF LT71141? Also, I connected my Durmatic up and I am getting a communications failure to the tip, however I am able to communicate with the engine and see no fault code.

I need to replace the leather door panels on my 986 Boxster, but could only find a set from a 987. Does anyone know if they will fit? I know that people have replaced the doors on a 986 with a 987, but not just the panel. Thanks MJM

Vincent, I think you have issue. It takes a 5 mm hex head and maybe an hour to change it, including taking the right tire off. -m

Vincent, I just got her running and it was the Pulse Sender (aka Crankshaft Position Sensor) and it is called a "Impulse sender" at Pelican Parts. Odd I had no faults on the Durametric?

Vincent, I am a EE and make a living from troubleshooting and solving difficult problems and this one should be easy. I've ordered more tools to aid in troubleshooting, but still looking for a good fuel pressure gauge. I would like to find a pressure kit that will also work on my Mercedes, BMW and Lexus. They all have the Bosch system. Did you or your shop try the Pulse Sender? I will let you know as soon as I solve this one and please do the same. Thanks -Michial
