09G Overhaul Kit 2003, new and ready to install. Fits the 09G. Ships fast from the USA.
Rebuilding a first-generation 09G six-speed automatic out of a VW Jetta, Golf, New Beetle, Passat, an Audi TT or a Mini Cooper? This kit is for early units, starting with the 2003 model year when the Aisin TF-60SN first went into these cars. It combines two things a slipping 09G needs: a full overhaul set of gaskets, rubber seals, O-rings and sealing rings, plus a set of friction plates for the clutches and brakes. Steel plates are not included, so you reuse good steels or buy them separately.
The 09G is the Volkswagen name for the Aisin TF-60SN, a transverse six-speed that also appears as the 09K, 09M and the 6F21WA in the Mini. It gets six forward gears from three clutches, K1, K2 and K3, and two brakes, B1 and B2, each applied by oil pressure from the valve body. K1 drives the car in first through fourth, so it carries more work than any other pack. Each piston is sealed with rubber, and oil reaches the turning drums through sealing rings, so a hard seal or a worn ring lets pressure bleed off. Once that happens the friction plates slip, heat up and glaze, and the transmission control module can only adapt so far before you feel flares and harsh shifts. Replacing the seals and the frictions at the same time is what restores holding power; fresh seals behind burnt frictions, or new frictions behind leaking seals, will not last.
Scan for codes and look at the fluid before you pull the unit. Not every early 09G complaint is worn clutches. Sonnax reports that worn clutch cutoff valve bores in the valve body cause erratic shift timing, harsh shifts, ratio codes and even burnt clutches, so a rebuild that ignores the valve body can fail again. Our Aisin harsh and delayed shift guide covers how to separate a hydraulic fault from worn plates, and the shift flare vs slip guide explains what each feel means. For the common failure patterns and what a rebuild costs, read our 09G TF-60SN problems and cost guide.
This listing is a 09G (TF-60SN) overhaul and friction kit for 2003-up first-generation units. The kit is cross-referenced to the 2003-2006 Audi TT 1.8T front-drive automatic, the New Beetle from 2003, the 2005-and-later Jetta and Passat, the 2007-2011 Golf/Rabbit and the 2005-2011 Mini Cooper with the six-speed automatic. Be aware that most 2003 Jetta and Golf automatics sold in the US still used the four-speed 01M, which this kit does not fit, so check the code on the case. Aisin changed parts inside the 09G over its run, including the accumulator body, so later 2014-up units should use the 2014-2022 09G overhaul kit. Send us your year and VIN if you are unsure. If you want new steels as well, the 09G master rebuild kit for 2003-2013 is the complete option, and every Aisin unit we support is on the Aisin transmission page.
Soak the new frictions in the VW-specified 09G fluid before assembly, inspect every steel for heat discoloration and flatness, and replace any that are blue or warped. Lube the sealing rings with assembly gel and air-check each clutch and brake circuit once the unit is together. Pay special attention to K1: Gears Magazine traced an intermittent no-forward on a Jetta 09G to a K1 drum hub that had separated from the outer drum, and a broken drum will defeat new seals and frictions. A 2003 09G clutch drum is available if yours is damaged. Check the 09G pump bushing and gears while the case is open. Finish with a new filter and pan gasket from our 09G filter and gasket kit, flush the cooler, set the level at the check plug at the specified temperature, then reset the adaptations and run the adaptive relearn.

No. It includes the overhaul gasket and seal set and the friction plates. Steels are not included, so reuse steels that are flat and not heat-blued, or choose the 09G master rebuild kit if you want new steels too.
Most 2003 Jetta and Golf automatics sold in the US used the four-speed 01M, not the 09G. Check the transmission code on the case; this kit only fits the six-speed 09G (TF-60SN).
The kit is cross-referenced to 2005-2011 Mini Cooper models with the Aisin six-speed, which is the same TF-60SN family sold as the 6F21WA. Send us your year and VIN so we can confirm before it ships.
A new filter and pan gasket, any heat-damaged steels, and a cracked K1 drum if you find one. Inspect the pump bushing and test the valve body, because worn valve body bores are a known cause of harsh shifts and burnt clutches on this unit.
Use the VW-specified 09G ATF, set the level at the check plug at the specified temperature, then reset the adaptations with a scan tool and complete the relearn drive cycle.
