S4 tip tranny in A4Q 1.8T tip?
Anyone have any info on if this is a possibility. This is from an old post from Neil M. about the 2 different ZF trannies used in A4/S4.
The following specs apply to both the quattro (5 HP 19 FLA) and FWD (5 HP 19 FL) tiptronics:
Transmission capacity:
T(max) Engine at 3500 rpm = 310 Nm
P(max) at 5500 rpm = 169 kW
(230 HP)
n(max) in 1st to 4th gear = 6540 rpm
n(max) in 5th gear = 5000 rpm
n(max) KD shift = 6000 rpm
T(max) Turbine = 540 Nm
Converter:
W 254 S with controlled converter clutch
T(p) = 90 -230 Nm at n(p) = 2000 rpm
Ratios:
1st gear 3.67
2nd gear 2.00
3rd gear 1.41
4th gear 1.00
5th gear 0.74
Rev. gear 4.10
Constant 2.2 ... 3.7
I contacted ZF Getriebe GmbH for information on the 5 HP 24 tiptronic transmission they supply for the S4 and A6 2.7T. The Tip in these cars is a 5-speed auto transmission with integrated center torsen differential and a front axle differential.
The Tip can handle 308 hp and 310 ft-lbs. They show 313 HP, but that doesn't follow the math I used:
HP = kW x 1.341
ft-lbs = Nm x .73756
Doesn't look like the Tip will be able to handle a chip upgrade with it only rated for 310 ft-lbs, but my A4 Tip is only rated for 228 ft-lbs and it seems to handle the PES with 265 ft-lbs with no trouble so far.
Transmission capacity:
T(max) Engine at 3500 rpm = 420 Nm
P(max) at 5500 rpm = 230 kW (313 HP)
n(max) in 1st to 4th gear = 7200 rpm
n(max) in 5th gear = 6200 rpm
n(max) KD shift = 7000 rpm
T(max) Turbine foward/reverse = 800 Nm/500 Nm
Converter:
W 260 S with 2 controlled converter clutches
T(p) = 78 -281 Nm at n(p) = 2000 rpm
Ratios:
1st gear 3.57
2nd gear 2.20
3rd gear 1.51
4th gear 1.00
5th gear 0.80
Rev. gear 4.10
Constant 2.63 ... 3.73
Weight with oil 141.1 kg

that wasnt very nice, but.....
If you could make the S4 6speed to to the 1.8T, than I don't see a reason you couldn't do the same to the S4 tip tranny. Whatever was done to make the surfaces mount wouldnt have to be done I'd gather.
Altho.. from the specs I posted, there are some integrated pieces on the S4 tranny (integrated center torsen differential and a front axle differential) that I'm not sure if they are in the A4 tip tranny
Hopefully someone who knows about this can help

Don't thinks so
An auto transmission's torque converter mounts to a flexplate, not a flywheel, I think that will be part of the problem.
Besides why do this? If youre looking to APR Stage III or PES T-28 upgrade, why not do the Level 10 transmission upgrade.

If you didn't see, I was talking about a swap from a tip to a tip
So there would be a flexplate in either car.
The Level 10 upgrade is far from proven as a capable upgrade. The S4 tip tranny is proven to handle the 300/300'ish power. You can get junked trannies with a 90 day warranty for $1500-3500, so depending on what you find, it's the same cost of the L10 upgrade.

Yes I saw, the point I was trying to make was
it's a different flexplate, likely. Do you know,is the flexplate in a 1.8 the same part # as in the S4? I'm thinking not likely, but any of the Etka's out there could take a look and help you.
Good Luck
