Master rebuild kit with gaskets for the Aisin 09G (TF-60SN) 6-speed in 2003-2013 VW Jetta, Golf, Beetle, Passat and Audi A3/TT.
A 2005-2013 Jetta, Golf, Beetle, Eos or Passat, or an Audi A3, A4 or TT, with the six-speed Tiptronic automatic that bangs into third, flares between fourth and fifth, or slips once the fluid gets hot needs more than a fluid change. When the clutches are burnt, the fix is a teardown with new plates, seals and gaskets. This master rebuild kit for the 09G (Aisin TF-60SN) supplies those parts, and the cross-reference numbers on it include T12900D, T12902A, T129080D, T129081A, 129300A and 129940, so you can match it against a kit number from a previous rebuild or a shop quote.
The 09G uses clutches K1, K2 and K3 and brakes B1 and B2 to produce six forward gears, and each one has its own control valve in the valve body. A useful habit during teardown is to note which pack is burnt, because the damage points to the circuit that failed. Sonnax ties specific valve body wear to specific burnt packs: B1 burnt with 1-2 and 5-6 flares and 2nd or 6th slip points to the B1 clutch control valve, a burnt K1 with coast-down neutral or delayed forward points to the K1 control valve, a burnt K2 with erratic timing and flare shifts points to the K2 control valve, and a 2-3 or 4-5 complaint with delayed reverse points to the K3 control valve. This kit replaces the frictions and steels in all of those packs plus the piston seals, sealing rings and gaskets, but it cannot correct a worn bore. Find the cause, or the new plates will burn the same way.
Scan for stored codes and record when each slip happens: which gear, hot or cold, and under how much throttle. That pattern tells you whether you are dealing with one failed circuit or a worn-out unit. Our Aisin slipping under load guide covers road-test steps and pressure checks, and the Aisin overheating guide explains why heat ends so many of these units. The linear solenoids can also cause flares and harsh downshifts. Sonnax notes Aisin linear solenoids can stick after a hot soak, so bench-test them hot, as described in our solenoid bench testing guide. If a solenoid sticks, add the 09G solenoid kit to the order.
The listed applications are 2003-2013 VW Jetta, Golf, Beetle, Eos and Passat, and Audi A3, A4 and TT, with the 09G six-speed automatic. These cars were also built with manual gearboxes and with DSG dual-clutch transmissions, which this kit does not fit. Confirm you have the 09G by the transmission code on the case or on the vehicle data sticker. Pistons and accumulator hardware changed during production, so compare the photos with your old parts, or send us your year and VIN and we will check fitment before it ships. Related parts, including valve bodies, drums and pumps, are on our Aisin transmission parts page.

T12900D is one of the cross-reference numbers listed for this kit, along with T12902A, T129080D, T129081A, 129300A and 129940. Compare the photos with the quote, and send us the year and VIN if you want us to check fitment.
That depends on which valve body circuit has worn. Sonnax links a burnt B1 to its control valve, a burnt K1 to the K1 control valve and a burnt K2 to the K2 control valve. Check the matching valve body bore before reassembly.
No. The DSG is a dual-clutch transmission with a mechatronic unit and shares no clutch or gasket parts with the 09G six-speed automatic. This kit is only for the 09G torque-converter automatic.
If the unit has high mileage or had flare and harsh-downshift complaints, yes. Aisin linear solenoids can stick when hot. Test them hot, and replace the set if any one is slow or sticking.
The 09G has no dipstick. Fill through the fill plug with VW-approved 09G fluid, run the engine, and check the level at the overflow plug at the temperature VW specifies. Then reset the adaptations and drive the car through all six gears.
