This is kind of incredible. Ray_V6TDI is a wildman!

Equally incredible is the lack of Samba action on this thread ...only 3 pages in 9 months? I think it has a marketing problem, the subject is not the greatest.
"Tiptronic-Modification now public Domain" did not interest me enough to open it. Today is the first time I even looked at the thread. With transaxles being the achilles heel of all (most) engine conversions, this is an extremely pertinent thread.

How many speeds are there in the Audi Tiptronic? How much HP does Audi run thru it? What's the Ring&Pinion ratio, and top gear cruising RPM etc? This info is necessary, and members are interested.

How about a Mod changing the subject? This title below would look more interesting (to me).

Can't speak to the Audi version, but for the 2WD VW version:

4-cyl (1.8T) final drive is 3.091, intermediate drive is 1.207

6-cyl (2.8 V-6) final drive is mostly 3.091, also 2.727, intermediate 1.207

4WD is a bit confusing because of the way the front and rear are split, but for the front the same two final drive ratios are available (3.091 and 2.727). W8 is 2.909 I believe.

I suspect the longer ratio for the V-6 may not have been North America, but I don't know. Also, I suspect the TDI version would be lower ratio.

Having always been a manual transmission person, I was prepared to not like automatics. But I ended up with an automatic Vanagon, and I can see the advantages. I have to say that I really like the Tiptronic also. I have bought three (in Passats) in the past couple of years. Two V-6 4-Motion, one 2WD 1.8t.

They are 5-speed, with lockup torque converter in all forward gears. The sport mode ('manual' shift) works better than any other similar that I have personally experienced. I use it often for fun.

The controller was pretty sophisticated for its day. Adapts to drivers and conditions. These would make an excellent transmission for a van, in my opinion. I suspect they are pretty durable as well. The ones I am using are all in the 300,000 km range. I have read the torque convertors can be a problem, and one of mine has a pretty strong shudder on occasion.

The 2.8L v-6 is 190 HP I think. Not sure of RPM, but it is pretty low at highway speeds. I can check later today if I am out.

I sure hope someone makes progress on this. It sure looks like a viable alternative to me. I believe I could handle the machining if I had everything in front of me and went with a three or even 4 piece design instead of two.

Unfortunately the Bridgeport mill I have access to needs to have wear parts replaced before attempting anything this precise.

I believe it is definitely worth pursuing, even if a shop needs to be hired.

WOOOW I fell in love with your work, I want to do the same in an automatic 4EAT Box with an ej22.

My question is, your pinion and differential crown how did it work? Why is it moving the force on the opposite side of the teeth?

New re-hosting because it came to my attention that the old links were dead. Hopefully this time they stick around longer

Nice conversion!! But isn't a porsche tiptronic much easier to adapt? Also much more expensive...

Unfortunately, no.

Different software in TCU,
different gear ratio 1-5
different middle gear ratio (the one to replace),
different axle distance between middle gears Porsche vs Audi
different bellhousing pattern.


Besides the mechanical issues, the first three mentioned do cause severe software isues and/or limp modes.

Regards

So I too just saw this thread.
Any chance the cad files are still around?
