09G Tcc Solenoid 2003-2015, new and ready to install. Fits the 09G. Ships fast from the USA.
If your Jetta, Passat, Golf, Rabbit, Beetle or Audi A3 with the 09G six-speed automatic has a hard bump that feels like an extra shift around third gear, a converter clutch fault in the TCM, or cruise RPM that never settles down, the lockup control solenoid is one of the first parts to check. This is a single replacement linear solenoid listed for the torque converter clutch circuit of the 2003-2015 09G, the transmission Aisin builds as the TF-60SN. Buying the one solenoid makes sense when diagnosis has already pointed at lockup control and the rest of the valve body is behaving.
The 09G valve body carries six linear solenoids and two on/off solenoids. Four of the linear units feed the clutches and brakes directly, one sets line pressure, and the last one controls torque converter lockup. Transmission Digest points out that the lockup unit is the odd one out: the other five linear solenoids are normally open and lower their output as current rises, while the TCC solenoid is normally closed and raises its output pressure as the TCM feeds it more current. The two on/off solenoids are also energized during lockup and engine braking, so the converter clutch depends on more than one electrical part. Pressure for every linear solenoid comes from the solenoid modulator valve, and Sonnax notes that low modulator pressure shows up as flared or long shifts and poor converter clutch apply.
Start with a scan tool that can read the VW transmission module and watch commanded versus actual gear while you drive. Transmission Digest stresses this step because a hard lockup apply in third is easy to mistake for a rough 3-4 upshift, which would send you after the wrong clutch solenoid. Compare engine speed against turbine speed at a steady 45 to 55 mph to see whether the converter is actually locking. Our TCC shudder diagnosis guide walks through separating a slipping converter clutch from a control problem, and the solenoid bench testing guide covers resistance checks and a hot soak test for a plunger that only sticks when warm. One caution specific to this transmission: the common trick of swapping solenoids between bores to see if a fault follows the part does not work with the lockup unit, because it is the only normally closed linear solenoid in the body. If codes name several solenoids or the fluid is dark and burnt, a full 09G eight-piece solenoid kit is usually the better buy.
This listing covers 09G transmissions from 2003 through 2015 in front-drive Volkswagen and Audi models. That span crosses the 2008 production change in 09G solenoid size, so with the pan down measure the can of the solenoid you are replacing and compare the connector and body shape to the photo before ordering. A slim 0.75 inch can and a 1.0 inch can are not interchangeable. If you cannot get to the valve body yet, send us your year and VIN and we will check it before it ships. Other Aisin six-speed parts are collected on our Aisin transmission page.

It is listed for 2003-2015 09G six-speed automatics, the Aisin TF-60SN used in front-drive VW Jetta, Passat, Golf, Rabbit, Beetle and related Audi models. Because solenoid size changed during 2008, measure your old solenoid or send us your year and VIN before ordering.
No. The lockup solenoid is the only normally closed linear solenoid in the 09G, while the clutch, brake and line pressure solenoids are normally open, so moving it to another bore will not give you a valid test. Use a scan tool and a bench or hot soak test instead.
Common signs are a firm bump when the converter locks in third gear that feels like an extra shift, lockup cycling on and off at cruise, higher highway RPM, and problems that only show up once the transmission is hot.
Use ATF that meets VW G 055 540 A2 and check the level hot at the fill plug. Since the valve body has to come down for this job, replacing the filter and pan gasket at the same time is good practice.
Yes. The lockup solenoid is not adjustable, so the TCM makes the corrections. Clear codes and run a relearn drive with the fluid at operating temperature; full adaptation can take up to 50 miles of driving.
If diagnosis points only at lockup control, the single solenoid is the economical fix. If codes name several solenoids, shifts are harsh across multiple gears, or the transmission has high mileage on the original set, the complete eight-piece kit is the better choice.
