09G Overhaul Kit 2003-2013, new and ready to install. Fits the 09G. Ships fast from the USA.
A first-generation 09G that weeps ATF at the pump or axle seals, flares on upshifts once it is hot, or hesitates before Drive after sitting is often losing pressure past hardened seals. This 09G overhaul kit is the gasket and seal set for Gen 1 Aisin TF-60SN units built from 2003 to 2013, found in the Jetta, Golf, Beetle, Passat and Audi TT. It is what you install when the transmission is apart and every sealing surface needs to be renewed at once.
The 09G is a transverse six-speed that VW buys from Aisin; the same family is sold as the 09K and 09M, and BMW and Mini call it the 6F21WA. Its clutches (K1, K2, K3) and brakes are applied by pistons fed through sealing rings on the input shaft and pump support, while the case, pump, valve body and side covers are sealed with gaskets and O-rings. With the valve body managing clutch-to-clutch shifts with tight overlap, even a small leak in a feed circuit shows up as a flare or a slow apply, and the computer then piles on pressure or sets a ratio code.
This kit (Gen 1 seal and gasket set, part number K79900HGX, interchange T265002A) supplies the gaskets, sealing rings and seals for that job. It does not contain frictions, steels, pistons, bushings or a filter, so if your K1 or K2 plates are burnt you will need clutch parts as well. The earlier description on this page claimed frictions and steels were included; that was not correct.
Set the fluid level correctly first: the 09G has no dipstick and is checked at the fill plug at a set fluid temperature, and many problems on these cars come from an underfilled unit. If shift complaints persist with a correct level, read our Aisin harsh or delayed shift guide. Worn valve body bores are a known 09G fault that causes erratic timing and burnt clutches, so a unit that shifts badly with good fluid may need valve body work as well as seals. On teardown, hard or nicked sealing rings with plates still in good shape mean this kit is the right buy.
This listing is for Gen 1 09G and TF-60SN units, 2003 to 2013. Aisin and VW updated the accumulator body, valve body and some internal parts over production, and the Gen 2 unit that followed uses a different seal kit, our 09G overhaul kit for 2014-2022. Late 2010 to 2013 cars sit near that changeover, so compare the old gaskets to the new ones before you start, or send us your year, model and VIN. If you want frictions in the box as well, the 09G master rebuild kit for 2003-2013 covers the same years. More parts for this unit are on our Aisin transmission collection page.

Gen 1, the 2003 to 2013 units. The Gen 2 09G from 2014 on takes a different seal kit, which we list separately.
No. It is a gasket and seal set with sealing rings. Frictions, steels, pistons and the filter are not included.
Gen 1 09G and TF-60SN units were used in the VW Jetta, Golf, Beetle and Passat, and the Audi TT. The BMW and Mini 6F21WA version is a related unit; confirm parts against your old gaskets or VIN before using this kit on one.
Only if leakage is the cause. Worn valve body bores and burnt clutches cause the same symptom, so check the fluid level, scan for codes and inspect the valve body before relying on seals alone.
The 09G is filled and checked at the check plug with the engine running at the specified fluid temperature. Fill until fluid runs from the plug at that temperature, then reinstall it.
Yes. Reset the transmission adaptations with a scan tool and drive through the relearn cycle so the module learns new clutch fill times.
