This is what happens to my 2004 NB Turbo 1.8 ltr. with Triptronic transmission (80.000 miles):
For as long as the transmission appears to be below normal temperature, everything is dandy. After a few miles of driving in D-position the transmission rocks once when it downshifts just prior to stopping the car. However, it doesn’t happen every the time when I apply the brake slowly. What might be the problem, how can I pinpoint it and how could it be fixed? Thank you for your reply.

Unfortunately you have the VW Automatic transmission standard feature or option.

After 70k miles depending if the car was a city dweller or a highway warrior the valve body wears in these cars and causing harsh and erratic shifting once the transmission fluid is warmed up. It will just get progressively worse if you do not repair the problem.

If you can DIY it is not a had job, maybe 3 hours. If you have to pay someone to do the job, expect $900-$1100 IF you can find a shop that will not want to perform a complete rebuid, which is typically not needed on the 09G 6 speed Tiptronic transmissions.

I am the original owner of a 2003 1.8t GLX Convertible with a 09G 6 speed Tiptronic transmission. Around 70k miles same problem as you are having, ALL of these cars have the same problem. I sent my valve body out for reworking and have put about 20k miles on the car since.

Search my user name in the Transmission section, I have a lot of comments and info on the issue.

VW actually extended the warranty on the problem, but all the cars are beyond the extended warranty at this point and VW has other problems to worry about with DieselGate!

Thank you jfoj. Questions : How can I confirm that my NB has a 09G transmission ? To do the job myself, what are the best (step-by-step) instructions to avoid costly mistakes and waste of time ? Where could I have the valve body rebuild or are there new or rebuild ones available ? Thank you again for your quick reply.

If your car has a 6 speed automatic with the manual Sport Shift mode on the right side of the shifter it is a 09G 6 speed Tiptronic.

If it is a 4 speed automatic it still suffers from the same problem.

You can shop the valve body around or you can have yours reworked.

I used Pacific Coast Transmission in CA and Johnny was very good to work with. They typically turn the valve body around in a day. They can rework yours or sell outright.

I prefer to have my valve bodies reworked vs an exchange or replacement.

Hardest part is keeping track of the wiring and disconnecting the stupid solenoid wires without breaking anything.

O.k. it is a 09G 6 speed Tiptronic. Where/how can I inform myself regarding to removing/installing the valve body prior to starting the work ? Would the Bentley Service Manual be the best choice ?

Search the Transmission section here, I have a lot of info and I think some others posted a lot of info as well. Also search Workshop manuals.

On my phone, but short story , buy a set of Rhino ramps for $40.

get a large diameter oil drain pan.

About 9 bolts to remove the trans pan.

Keep bolts grouped and bagged as you remove them.

2-3 bolts for filter. I recall about 12 bolts for the Valve body. Take pictures, mark wiring, write a diagram.

Valve body is heavy/tall, not real heavy, but bigger and heavier than you would expect.

You fill trans from the buttom drain, DO NOT TRY TO FILL TRANS FROM UPPER FILL PORT.

After reinstalling valve body and connecting wiring, but before pan is installed, turn ignition on, do not start engine, run trans through the gears and make sure no errors show up. Ask me how I know!

Thanx jfoj, you provide excellent and very helpful information to the community.
I still have a question concerning the valve body removal: My NB has a metal skid plate below that covers the engine and transmission and (it looks like) is held at its rear end by the two sub-frame mounting-bolts. If I am correct, do I have to unbolt the sub-frame to get the plate off ? Thank you for your reply.

The NBC skid pan is held on by mostly Triple Square or XZN fasteners. There a 2 standard bolted in the rear of the skid plate that only attach the skid plate. There are no suframe bolts to deal with. Go on Amazon and buy some XZN bits, you will need them. I remove the skid plate for every oil change.
