i'm trying to complete my t-56 swap into my a4 3'rd gen. i have everything i need except the master/slave cylinder. i bought a used one off of a v6 3'rd gen. but it doesn't seem to fit properly.

are the t-5 master cylinder/ slave cylinder different from the t-56 ones?

 

In a word, yes.

 

The master and slave would work but the line is too short.

Get the T56 hydraulics.

 

yea. thats the problem i ran into. i looked at some one who did the swap on here. and from the pictures it looks like the t-56 has hydraulic lines while the t-5 has some kind of plastic.

And another really important thing i noticed after trying to stab the tranny in. is that it seemed like the fuel lines that ran over the top of the transmission tunnel didn't allow enough clearance for the t-56. so i decided to reroute the lines to run up on the driver's side of the engine bay.

 

The fuel lines on the fuel injected cars come all the way up and into the engine compartment on the drivers side. Only the carbed cars have them cross over the top of the trans tunnel and on the passengers side. Still it's odd that no one has ever mentioned that problem before.

The T56 slave cylinder bolts toward the rear of the car, while the T5 cylinder is towards the front. Hence the line has to be longer to reach. The change from the plastic line to braided stainless is probably to protect the line over the longer distance.

 

thanks drew.
i really appreciate it. mine in fact was a carbed car from the factory. i had to run a bigger return line to match the feed line. that is probablly why it was too tight. it was only about .25 in off.
