So someone on here told me to get a 17mm allen key for the tranny fluid change. I spent about 2 days looking for this part. It turns out its wrong. Does anyone kno wthe really allen head key size?

 

I dont know the answer but have you looked into purchasing the Bentley repair manual for your TT?

Might help avoid having to wait for someone on here to answer a ? for you.

 

You WILL need something to undo the plugs. It should be a 14 mm Allen Wrench (that is for my 2001, I hear later years may use different bits), that no one has [edit: I have found a set of 14/17/19 mm wrenches at AutoZone]. In it's place, I used a 3/8" bolt and two nuts. The head of the bolt is 1/2", or 12.7 mm, which is undersized for the 14 mm socket, but it worked...

 

make sure you clean the bevel case magnetic drain plug

 

How did you re-fill ur tranny A6? Any special tools required...

 

you'll just need a grease gun to push the oil into the fill hole. and the tools listed above. its very easy process. takes 3 qts redline mt-90 i'll post a link to a very good write-up Mcphill(should be on Mr.Schwings foki page listed as a friend)

 

Buy a 3/8" coupler nut at the hardware store for $1.50 and file it down a tad so it fits the hex properly. Then you use a 9/16" or 14mm socket on the other end. Fill it till it runs out; you can buy a pump at the auto parts store for about $4 that screws into the 1 qt. bottles of synthetic 75-90 (I used Mobil 1).

Consider doing the rear diff as well; a 1/2" coupler nut fits it, plus a little filing as well. 4 qts. will take care of both trans and rear diff.
