Audi 01E Quattro Transmission

Porsche 968 - 01E 6 Speed Transmission

The Porsche 968 has a version of the 2WD 01E transmission.  
It looks like there might be some of the parts that would 
interchange, if you were so inclined.

The 968 has this transmission in the rear of the car driving 
the rear wheels, with a long torque tube affair connecting it 
to the engine way up in the front.  Interesting differentials 
listed are:

        950.332.053.00  40% ZF Limited Slip Differential
        950.332.063.00  Torsen Differential

So if anybody has been looking for a front differential, 
in an excess of something-or-other, here's your chance!  
Before you spend money on this, check the ID/OD of differential
carrier side bearings to make sure this will interchange.

I think the only gears that would interchange are 5th and 6th.  
The 2WD and Quattro version 01E transmissions should be able to 
interchange 5th and 6th gears, which offers some possibility
for different ratios.

The 968 2WD has these ratios:

5th:    0.912    31/34    Standard ratio
        1.04     24/25    Special order ratio

6th:    0.778    28/36    Standard ratio 
        0.89     28/25    Special order ratio

These will not help much with the standard Audi 01E Quattro 
ratios for 3rd and 4th gear.

A NOTE FOR PORSCHE 968 OWNERS:


I've found that Porsche no longer stocks the 1/2 shift operating sleeve 
for the 968 transmission.  Since this is a part that fails, this leaves 
the 968 owner needing to replace the entire transmission when this part
fails!  Porsche no longer even lists a part number for this piece.




It turns out that the 2WD version of the Audi 01E transmission uses the
same part, and Audi has the part number listed.  

The part number you need is 01E 311 239 E  - this is the 1/2 shift hub
and operating sleeve.

This is an Audi part for a 2WD 01E transmission, which was used in the 
European 2WD V8's and 2WD European A8's.  2WD A8s with a V6 were produced
at least though 2002.  Also check as A4 2WD 6 speeds may still be in 
production.

I checked with the large Porsche & Audi dealer here in Columbus, they
say this is a good part number but they can't order it, 2WD V8 powered
cars were never imported into North America.  You will have to get 
someone in Germany to order it for you.  

For interest, the Porsche 968 and Audi V8/A8 2WD 6 speed transmissions
use the same part numbers for these parts:
   1st syncronizer band
   2nd syncronizer band
   1st gear needle bearing & needle bearing hub
   3/4 shift hub
   5/6 shift hub


Based on that, I think the 01E 311 239 E Audi part is the right part 
for the Porsche 968 transmission 1/2 shift hub and operating sleeve.
