The Official Unofficial Tiptronic Thread

[psquared39]

Never drive in any mode but M. Keep revs between 3-4k at steady driving. When in a 55 zone the car does not need to be in 5th, fourth runs at 3100 or so. You can learn to down shift "safely" breaking with left foot and throttle blipping with right to rev match. Ya, the 02 isn't new enough for the computer to do that. Completely different than the wife's 2014 Q50, the computer does the rev match for you as all new cars do. Tip in manual mode is a great experience, don't miss driving a stick.

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.

Off the comments in that article I was figuring to have 7 liters on hand, but in the article itself he says to have a container that can hold 12 liters for draining. I'm not looking to do a complete flush like you did. Trans shifts fine, just figure it's time to do the filter change.

Yeah, that wheel looks great, but the price doesn't.

How would you get the filter changed unless you drain the sump?

I do plan to drain the fluid and pull the sump. Most of the comments said said 6.5 liters was all they could get back in.

How much fluid do you think I need on hand?

[psquared39]

Like i stated in the previous post i was unable to find a mechanical method to flush the transmission, so i approached the the manual way, and just changed it 4 weeks in a row, last time dropping the pan and changing the filter. From a visual standpoint that last drain with filter change the oil was looking like it came out of the bottle, flush success... Not that it was performing poorly before, but there was a noticeable difference after i completed this process.

Ok I have a 99 with a tip transmission but the M mode doesnt work. any good diy for diagnosing? It hasnt worked since i bought the car. will a durametric help to diagnose?

Does it do anything in "M" mode?

[mikesz]

nothing happens when put in M mode

So the car won't even move? When you put it in M does the M light come on the gauge and does it show it in a gear? You need to give more info as it may be a sensor/linkage issue in the selector or the steering wheel and may not have thrown a code but you should check that as has been mentioned.

I would suggest checking all of the mechanical switching system first. Does it show up on your dash indicators when you switch from D to M? If not you may have an issue with the contacts on the shifter. After that I would work my way back threw the system. If you are not getting the flashing 4toD limp mode it's more than likely a dirty contact somewhere. In the switching system. Hope you do not have an issue with your TCM. I could be wrong it's been awhile but I do believe it's a separate computer for the trip.

You need to get the codes read. A Durametric will give you this info. Possibly a wiring harness issue, but you need to get the diagnosis.

[KRAM36]

The Durametric has a section for the Tiptronic. It will store the code(s) ,if any, there. If you don't see any code(s), then Luv2Box probably hit what to look at.

[mikesz]

ok thanks. I will check to see what the Durametric tells me. Another issue is the ground wire in the steering wheel isnt grounded! I swapped 4 spoke for a 3 spoke and there was a brown wire that wasnt connected to anything. As I check around grounding seems to be important for operation of the tip tranny. I am missing the clip on the brown wire that goes to ground. anyone know where I can get one of those clips?

[Luv2Box]

I would try a dealer like Suncoast (google them) or a local dealer. Looks like you may have found the problem.

[mikesz]

does any one know where the brown wire in the lower left hand corner connects to?

[mcdandc]

Have you checked online for the wiring info? Good luck, I'll be following..

I found a couple interesting threads while I was poking around in VW land today. Thought they might be good to link here.

Hello all !

Been reading here for quite a while but now have something to contribute.

When starting off from a stop the Tip's default is to start from 2nd gear, whether you're in Manual mode or Automatic. The "stutter" will happen all the time but is most noticed while pulling away in a casual, non-aggressive accelerating manner. You start off - then notice that it feels like it shifted but didn't shift gears. This is the torque converter locking up. No problem, normal.

It is highly recommended not to power flush the Tiptronic !! Bad things can happen. Instead, do a succession of fluid changes in a short amount of time. Each time the fluid is changed, you put in approx 4-1/2 liters of new fluid. Drive for a week to mix it up, then do another change. If you figure that after the first change you've got 50/50 old and new, a second change would make it 75/25, a third would be 87.5/12.5, etc. You don't get all the fluid out unless you take the trans and converter out of the car and disassemble.

Next, make sure you get the amber color Pentosin fluid, not the red color. After purchasing my 04 Boxster with 30k miles I took it to a highly respected independent that worked mainly on German cars. Did the IMS, RMS, AOS, plugs, oil, and trans service. They grabbed the wrong Pentosin made for the Mercedes Tip. The trans ran better and worse at the same time. I thought it was due to being low or too full, yes both are possible. When I checked the fluid level, red fluid came out! After that I changed the fluid myself even though they offered to make things right. I just didn't trust the situation and I found out it's pretty easy to do. After several changes the trans is doing great.

BTW, the IMS was in pretty good shape but the spindle had a wobble of about 1/16", so I am very glad I had it changed to the LN Engineering bearing.

Hope this info helps those that are in need.

Hi. I am new to this forum.

I am actually searching for an auto transaxle gearbox for a custom project car. Its not a porsche. It will largely be my own thing once its done.

My only real concerns are torque capacity, availability and cost. I will likely use a diesel V6 with around 600nm. Can the boxster or cayman box handle this without modification? If not, can it handle it with modification?

Thanks. Rhett.
