The Official Unofficial Tiptronic Thread

[Luv2Box]

I have noticed that none of the Boxster sites has a particular thread that relates to Tiptronic transmissions so I thought I would start one that caters to Tiptronic issues, solutions, general knowledge and conversation.
My 1999 Boxster came with a Tiptronic trans which I generally drive in "M" mode and after five years of use still thoroughly enjoy and would not go back to a stick. It has operated flawlessly in AX, DE and spirited back road driving. I've never had a problem keeping up with more powerful cars on twisty road driving and my left foot enjoys tapping the footrest while my thumbs do the shifting work. I enjoy the fact that I can't over rev the car and I'll never miss a shift and don't have to "paddle the canoe" in traffic or worry about roll back on hills with stop signs.
I hope this can be a place to help one another with Tiptronic issues that may arise, although mine has performed without incident.

I'm still trying to figure out how to really use the tip. I've been driving it for about six months in an 01 Base and it still feels awkward to me when I use it in 'M'. Most often now, I just leave it in 'D' and poke it with my thumb for decels when it passes below about 3K. Once I'm ready to accelerate, I do a quick left-right with the stick to set it back to D.
I should probably read my owner's manual for tips on the tip. I'd really like to get the most out of it. For now I strongly prefer my 5-speed unless I'm just driving around town for groceries.
Any suggestions (practical exercises?) on how to re-train myself to drive it properly?

[KRAM36]

I love my Tip. Had it for 2 years now and have learned how to use it correctly. Yes I highly enjoy leaving my left leg planted and both hands on the steering wheel.

I've read that the tips are pretty robust. Mine suffered from a problem in the harness, having to do with the temperature sensor if I remember correctly. It was doing the D and 4 winky thing but functioned normally. I drained the transmission, removed the bottom, and replaced the harness. Not a difficult job, just finicky getting the levels right on refill. Works fine now.
I occasionally miss the tactile, mechanical feeling of the stick. You feel more connected. But NOT in traffic!!

Jake Raby mentioned a 4.0l 400+ HP engine and I asked him if the Tip could handle that much power. Here is what he said.

With disassembly I can turn that engine into a 4 liter and get over 400HP from it. Its routine around here.

You're making my mouth water. Can a Tiptronic trans handle that much power?

Yes. The tip will handle more power than a manual.

Porsche's Tips are made by Mercedes and are tanks. They should not have a problem with that hp.

Some info regarding the Boxster tip.

1997-1999 Porsche Boxster: Model A86/00
2000-2004 Porsche Boxster: Model A86/05
2000-2004 Porsche Boxster S: Model A86/20

designed and built by ZF Friedrichshafen AG's subsidiary in Saarbrücken

The generic and base model name for the trans for buying parts and referencing is

ZF 5HP-19

ZF 5HP19 transmission - Wikipedia, the free encyclopedia

Introduced in 1996, it is still in production, and has been used in a variety of cars from Audi, BMW, Porsche, and Volkswagen Passenger Cars. in modified configurations it is used in all wheel drive audis.

Weak points are the torque converter bushing and the cooling valve. Be careful when replacing the hose leading to the cooling valve as the aftermarket replacement nylon hoses will melt and not allow the trans to cool and will allow the trans to overheat. If you have a trans leak at the bell housing do not just replace the torque converter seal. check to see if the bushing is worn out because if it is worn out, you will be just wasting your time replacing the seal.

Most of the time you will not find much info in the porsche forums relating to these, but if you go to the other forums where this transmission is used like the BMW forums you will find all the issues these trans are known for. They actually have guys tearing down and rebuilding these transmissions, and posting repairs.

After reading healthservices post, I though this might be a good spot to post a little more info.

Here's the PelicanParts Tip service DIY:

A ZF 5HP service video from ZF. Not the best video, because the fill port is apparently on the side of their demo model (BMW?), rather than the bottom:

A better video, but on an Audi A4. It is pretty much identical to our version of the ZF 5HP19:

If you want to see an in-depth tear down of the transmission look for YouTube videos by "Jeff Richardson" (BMW version of the transmission)

Here's the manufacturer's parts catalog for the Porsche 5HP-19 FL. It has some good diagrams and the fill procedure:

There's some pertinent information on this thread concerning draining and refilling the tip:
Engine on the floor. Now what?

+ 1 on your take on the TIP. Don't forget there are 5 driving 'maps' in the computer that ups the performance depending on your driving style. Good to know it would handle more HP as it certainly could use more....

I have a tip and love it. So does my wife who can`t drive a manual.

[Nine8Six]

Tiptronic all the way, wouldn't go back to the stick either. Even got the thick 320mm wheel and paddle shifters that completes the kit

Oh and, I became so good at it that I can blip the throttle between gears / right before downshifting. Used only for a little illegal accel, in the tunnel, when nobody is looking! It just sounds really good (that, with the ricer sound of the 2.5L). Blissss

Where did you get that steering wheel?

Brother you need to feed that engine some air!

This is a RAID steering wheel if I am not mistaken (my indy installed it for me by mistake lol). Not entirely cheap when adding the paddles but quality is unbeatable - does feels exactly like the Ferrari wheel; thick, heavy, solid core/metal, no vibrations, immortal nappa leather and threads

Only avail in the EU for some strange reason

[KRAM36]

Thanks for the info, yep they are not cheap price wise.

How much fluid is needed when doing a filter change?

Thanks!

So if you're doing the filter change, you should have 12 liters on hand?

[psquared39]

KRAM36, changed my 02 when i bought it at 46k 6 years ago, if i remember correctly about 6L was enough with pan drop and filter change. Last year i bought a 20L Pentosin from amazon for about $220. the car was at 86k. For three weeks in a row i drained and refilled (drain without pan drop and filter change was only about 4L), on the fourth week i drained, dropped the pan and changed the filter, this was the only method i could figure for a "flush". turned out just right with the 20L jug. What a noticeable difference in transmission performance. just my experience, hope it gives you some direction.
