09G Solenoid Kit, remanufactured and ready to install. Fits the 09G. Ships fast from the USA.
If you are searching for a 09G solenoid kit, you probably own a front-drive Volkswagen or Audi with the Aisin six-speed automatic and a shift problem that a fluid change did not fix: a bump into gear, a flare between gears, or a solenoid fault that drops it into a fixed gear. This remanufactured kit is the full set for that valve body. As pictured it holds eight pieces: six linear solenoids, with yellow, brown, tan and three black connectors, and two compact on/off solenoids with bolt-down tabs.
Volkswagen used two related Aisin six-speeds. The 09G is the transverse TF-60SN found in front-drive cars such as the Jetta, Golf, Rabbit, New Beetle and Passat. The 09D, or TR-60SN, is the longitudinal version used in the Touareg and similar models. Sonnax notes the two work much the same way but their valve body parts do not interchange, so a 09D owner needs different parts. The transmission code is on the case tag and on the vehicle data sticker.
Each clutch and brake in a 09G has its own linear solenoid, so the TCM builds every shift by lowering pressure on one element while raising it on another. Transmission Digest's study of a 3-4 upshift shows the K2 clutch applying while K3 releases, with about 100 milliseconds where neither is fully holding. Stretch that gap past roughly a quarter second and engine speed rises as if in neutral, then drops, which you feel as a flare followed by a bump. Apply the next clutch too early and the gearbox briefly tries to run two gears at once, a bind-up. Worn solenoids that respond slowly or deliver the wrong pressure for a given signal produce exactly these errors.
Read TCM codes and note the circuit named. Then check each solenoid's resistance and operation; our multimeter solenoid test guide covers the electrical checks, and the bench testing guide covers function. Because a plunger can stick only when hot, Sonnax recommends heating a suspect solenoid and checking that the plunger moves freely.
This listing covers the 09G without naming a year range, so match the parts before ordering. VW changed the solenoid can size during 2008, and earlier units use a larger can than later ones. Drop the pan, measure a linear solenoid can, about 1.0 inch versus about 0.75 inch, and compare connector colors and the tab-mount solenoids with the photo. You can also send us your year and VIN and we will confirm the match. Other six-speed parts are on our Aisin transmission page.
Aisin calibrates this valve body with adjustment screws rather than adjustable solenoids. If a specific shift is still off after a relearn, either the valve body needs calibration or its bores are worn, and a 09G valve body with solenoids is the complete answer.

The 09G is the transverse front-drive Aisin TF-60SN and the 09D is the longitudinal TR-60SN. They work alike, but Sonnax states their valve body parts do not interchange, so this kit is for the 09G only.
Eight, as pictured: six linear solenoids with colored connectors and two small on/off solenoids with mounting tabs.
Measure one linear solenoid can with the pan off, roughly 1.0 inch on early units and 0.75 inch on later ones, and compare the connectors to the photo. If you would rather not guess, send us your year and VIN.
That pattern means too long a gap between one clutch releasing and the next applying. A slow linear solenoid is a common cause, though worn valve body bores or low fluid can do the same.
Usually close, but the TCM still holds adaptations learned on the old solenoids. Reset them and run a relearn drive; otherwise it can take up to about 50 miles of normal driving to settle.
