09G Solenoid Kit 2006-2015, new and ready to install. Fits the 09G. Ships fast from the USA.
When a Volkswagen or Audi with the six-speed 09G automatic starts banging the 3-2 coastdown, flaring between gears once it is fully warm, or dropping into limp mode with a solenoid fault, the electrical side of the valve body is the first place to look. This kit replaces the complete set: as pictured, six linear pressure control solenoids and two small bracket-mounted on/off solenoids, the full eight-piece complement of the Aisin TF-60SN that VW calls the 09G. Replacing all eight at once gives every clutch circuit the same fresh response instead of mixing new parts with tired ones.
The 09G has no conventional shift valves switching clutches on and off. According to Transmission Digest's breakdown of Rostra's research, it uses six linear solenoids and two on/off solenoids. Four of the linear solenoids directly control clutches and brakes (N92 for K1, N282 for K2, N90 for K3 and N283 for B1), one controls line pressure and one controls torque converter lockup. The TCM drives them with a 300 Hz pulse-width signal, so it can ramp one clutch off while the next one comes on. The two on/off solenoids are normally closed and are energized for jobs like engine braking and converter lockup. Because every shift is an overlap between two or three elements, one slow solenoid is enough to spoil shift quality even with healthy clutches.
Pull codes from the TCM with a VW-capable tool and note which solenoid or clutch is named. A hot-only complaint points strongly at the solenoids: Sonnax describes plungers that begin to seize in their coil bushings at operating temperature, so a part can measure fine cold and still cause the problem. Resistance, function and hot-soak checks are covered in our guide to bench testing transmission solenoids. If the fluid is black and burnt, clutch wear has likely started, and if the complaint is a true slip rather than a flare, read our flare vs slip explainer before spending money on electrical parts.
This set is listed for 09G transmissions from 2006 through 2015, which covers front-drive VW Jetta, Passat, Golf, Rabbit, Beetle and related Audi models. That range crosses the 2008 change in solenoid size, so it is the one thing to check before ordering. With the pan down, measure the can of one linear solenoid: our large-can 09G kit with filter and gasket fits the 1.0 inch style and our slim-body 09G kit fits the 0.75 inch style. Compare the connector colors and the two small on/off solenoids against the photos, or send us your year and VIN and we will confirm before it ships. More Aisin six-speed parts are on our Aisin transmission page.
If new solenoids do not cure a hot flare, bore wear at the solenoid modulator or clutch control valves is the next suspect, and the valve body itself needs attention.

Eight, as pictured: six linear pressure control solenoids and two small on/off solenoids with mounting tabs. That matches the 09G layout of six linear and two on/off solenoids, so the whole valve body is covered in one order.
The listing covers 2006-2015, but the 09G changed solenoid size during 2008, so the year alone does not settle it. Measure one linear solenoid can with the pan off (about 1.0 inch versus 0.75 inch) and compare connectors with the photos, or send your year and VIN and we will check it for you.
The most common reason is a solenoid plunger that drags in its bushings once it reaches operating temperature, which shows up as a harsh 3-2 or a flared 2-3 above roughly 85 C. Worn bores in the solenoid modulator or clutch control valves can cause the same complaint, so if fresh solenoids do not fix it, look at the valve body.
Not always, but every 09G shift overlaps two or three clutches, and mixing one new solenoid with several worn ones can leave the timing uneven. Replacing the set avoids pulling the valve body a second time.
Use ATF meeting VW G 055 025, filled and checked at the level plug with the engine running at the specified fluid temperature. No programming is required, but reset the adaptations with a scan tool and drive through every gear so the TCM relearns the new solenoids.
