Tiptronic Transmission problem

[Branko Ljubetic]

Hi. Im new in this forum, and i registered search for help, so thanks in advance.

I bought a 97 boxster tiptronic, with no issues at all. Scanned, everything was ok. Then i started to read about the model, and i was concerned about de IMS, so i replaced it with parts from Pelican. I took the oportunity to drain the torque converter and replace fluid (filters gaskets also) on the tiptronic transmission. Then my mechanic built everything, and the lights on the gear and lever on the panel were blinking. Also cant use "manual mode" nor the 5th gear. He checked everything, but the problem are still there.

Searched on the interenet, seems to be something called "limited driving programme" where the transmision limits itself in event of a failure. On the internet also i found most of time is related with transmision servicing, but i changed all fluid (torque converter including).

I used the recomended ATF by manual (pentosin) and changed filter, gaskets from ZF (the transmission manufacturer).

Sadly, i live on a small city in Northern Chile, almost 2000km from a Porsche authorized mechanic in capital, Santiago, so its not an option to take the car there.

My mechanic here is a really honest guy, but he seems to not understand this transmission. I dont know what to do, but ill scan the car in a few hours.

Any advice will be hughely appreciated guys. Thanks a lot.

Welcome to the forum.
The procedure to fill the transmission requires that the transmission is warmed up, then filled to the drain level with the engine running. Make sure it was done properly.
Here's the parts catalog from ZF. The fill procedure is included around page 7:

Here's a clip of what it says:



I have done this on a Boxster and a Cayenne. I do not like being under a running vehicle while it is in gear. Take precautions.

Well, thabks fr the help. My mechanic downloaded a set of "european cars drivers" for his scanner, then deleted the fault and everything went good, so the tiptronic is working flawlessly right now. Thank you.
