The 2.8 B5 Transmission Swap DIY

[dougyfresh]

is all the linkage the same between the 5 and 6 speed? I am sure that the shifter is different. I wonder if the B6 6speed shifter can be used.

Nope. The linkage is different. If you source a 6spd get the linkage from the shifter down to the trans. All of it. You'll save yourself the hassle.

Where are you going to get one? They are difficult to find and crazy expensive.

btw, the b5s4 tranny is different than the b6 a4 6 speed tranny... and the b6s4 tranny is a different tranny again... some have different final drive ratios, so you'd need to swap the rear diff too... keep it simple guys

Hence the $4K+ bill for a used one with all the associated parts to swap...

Hence why I'm focusing on a 2.8L 5spd. I figure the taller gears will be fine for me. My friend's 1.8 Golf had a taller 5th gear (out of a TDI) and I liked how that drove. For me, its perfect since I'm all highway. hahah. Liter o'Cola anyone?

[CO AVANT]

Do we have liter cola?

[dougyfresh]

That's alright. My car will have wings...

[AudiA4_20T]

... so confused

[dougyfresh]

... so confused

Go watch a certain movie that is set to take place in Vermont.

[cjslapshot]

true, I may sell mine soon, I dont know if I can get used to long gears... That 1.8T trans is still there hmmm

just hold on to it bro... you'll be flying through those gears with a BT and driving down the shore/ back to school will be alot easier with the longer gears.

[AudiA4_20T]

Ok I have another 2.8 Transmission for sale $400 and I can do the swap for you for more $$

[absolutegtr]

Out of what year?

[AudiA4_20T]

Out of what year?

Hmmm I forget... 98 Im gonna say

[GarbatyA4]

THANK YOU SO MUCH

I've been looking for this, you are the man. Awesome job, I give you mad props for doing it in the parking lot. Read the whole thread. Wicked.

I'm getting me a 2.8L Trans. cuz my GT2871R needs it :D

Cheers Everyone!

Good Job Clint!

b6 6 speed into a b6 5 speed?
worth it?

[Frey7190]

You actually feel comftrable leaving your car bumperless in a college parking lot?? Dont you know what they could all do?? They could take those nice E-codes and ABT grill in a jiff... Not to mention the intercooler and other parts...

Is it even legal to work on your car in a parking lot??

[infernocl]

B6 6spd final drive is 4.111 same as B5 S4, also same 01E numbers
B6 5spd and B5 5spd have 3.89 final drive
B7 A4 and B6/7 S4 6spd have 3.89 final drive

swapping a B6 6spd or B5 S4 into a 5spd will require a new rear diff

B7 2.0t 6pd has lowest gearing for hwy crusing ~88mph/3000rpm, even the 5th in 2.0t is longer than 1.8t 5spd trans

B5 V6 in 5th is the same gearing as B6 in 6th gear ~75mph/3000rpm
B5 1.8t gearing is a bit longer than B6 5spd, ~200rpm drop at 65mph.

[red_rock_beetle]

so will a b7 2.0t 6 speed and rear diff fit an 02 a4 wit a 5 speed

[dougyfresh]

I think so, but don't quote me.

It'll be cheaper to swap the 5th gear out for a European TDI 5th gear. That is my plan in the future. I can then go back to my 1.8T trans (have a 2.8 now) and have an overdrive 5th gear yet still haul ass through gears 1-4 since they are shorter than the 2.8.

No doubt, glad I could help

No I dont. I know what "they" could do, but I had no money to get a bumper or anything at that time. Its probably illegal to do what I did, but I needed to get my car going again, and I did for ~$150

so will a b7 2.0t 6 speed and rear diff fit an 02 a4 wit a 5 speed

Can you get a B7 trans and rear diff? Id imagine youd be paying ~2k+ for just those pieces

[NyteEscape]

wow...i know where you did that...kinda wanna come see it now...

B7 6spd bolts on stock 5spd rear diff, not sure about the center drive shaft tho

Looks like the 02X and 01E are both options for what kind of trans the B7 has, Bentley doesn't make it too clear. If its the 01E thats the B5 S4 trans, which would mean that a B7 trans is = to a B5 S4 trans which would be pretty cool. The question is what the 02X trans came in

[red_rock_beetle]

i've been looking at the bentley software and you are right , its not very clear, maybe with further study

[infernocl]

Audi only uses 2 types of CV joints, and the smaller 100mm CVs from 4000s are not found on the A4s thus the center drive shafts and flanges must be the same 108mm CV joints.

all audis share bell housing patterns as well.

if the front fits and rear fits, all you need is linkages.

01E trans part numbers are no longer in B chassis according to ETKA from 05.5, even if it's 01E, the final drive matches the 5spd at 3.889 and CV joints are still the same

of course if someone actually wants to dump a few grand, some precise measurements are needed

your stock axle flanges should just press in like i did with the 2.8... Bellhousings are all the same also...

Linkage shouldnt be a huge deal. Im just curious about what the differences are between the 02x and 01e

[red_rock_beetle]

linkages should be the same if you got everything, shouldnt it?
isn't the B7 just a modified B6 ?

[infernocl]

i *think* 02X is based off diesel

[osofast10]

clint i need to talk to you... check your PM

[Casius]

Are all the 2.8 trannys the same?

[B6Lovin]

[Casius]
