09G Shift Kit 2003-2008, new and ready to install. Fits the 09G. Ships fast from the USA.
If your Jetta, New Beetle or Passat with the Aisin six-speed automatic slams into gear on a hot coast-down, lets the engine run up between shifts, or shudders at light cruise, the clutches are often fine and the problem is in the valve body. This is the TransGo SK 09G, a valve body repair kit for the 09G (Aisin TF-60SN) used in Volkswagen, Audi and Mini cars. It replaces the hydraulic parts that wear out, so the shift quality comes back without buying a complete valve body.
The 09G is a transverse six-speed with an electronic valve body. Each clutch has its own linear solenoid, and those solenoids do not apply clutches directly. They send a signal pressure to regulator valves, and the valves decide how fast and how firmly a clutch fills and releases. Sonnax uses this exact transmission as its example of an Aisin six-speed whose valve body is sensitive to calibration. As the valves and their aluminum bores wear, signal oil leaks off, pressure rises slowly, and the computer cannot get the crisp apply it is asking for. The SK 09G puts back the control: TransGo lists a TCC regulator valve and bushing in the kit, the listing adds parts to restore the pressure control solenoid circuits, and the valves are drop-in pieces made for this valve body.
Scan the transmission control module for stored codes first, then pull a fluid sample. Fluid that is reasonably clean with no heavy clutch material points toward the valve body and solenoids; dark fluid full of debris means the clutches have already been hurt and a kit alone will not save the unit. Pay attention to when the complaint happens. A car that shifts well cold and gets rough only after a long drive is a classic hot valve-body and solenoid case. Our walkthrough on Aisin harsh or delayed shifts lays out the order of checks, and if a single solenoid is suspected, test it before you buy anything.
This listing is cataloged for 2003-2008 09G applications. The kit description names cars such as the 2005 VW Jetta and New Beetle, the 2006 Passat 2.0L and 3.6L, the 2006 Audi A4 2.0L and the 2008 Mini Clubman. TransGo's own fitment is wider and more precise: the SK 09G is listed for the 09G, 09M, 09K, AW TF-60SN and GAF21WA from 2003-13 with a 1.100 in solenoid can outside diameter. That measurement is the real deciding factor, because the 09G family changed during production. Measure a solenoid can, confirm the transmission code on the case tag, or send us your year and VIN before ordering. You can also browse every Aisin-built unit we carry on the Aisin transmission parts page.
If the bores in your valve body are too worn to repair, or a previous rebuild left it damaged, a complete 09G valve body with solenoids is the alternative; match its fitment to your transmission before ordering.

The 2.5L Jetta of that era uses the 09G six-speed automatic, which is the transmission this kit is built for. TransGo fits it to 09G family units with a 1.100 in solenoid can outside diameter, so confirm the transmission code or measure a can, or send us your VIN and we will check it.
No. The valve body comes out from under the car after the pan is removed. The kit is still detailed valve body work, so an experienced technician or a careful owner with the instructions and a clean bench is recommended.
Converter slip and shudder are among the complaints TransGo lists for this kit, which includes a TCC regulator valve and bushing. If the converter clutch lining itself is burned or the fluid is badly contaminated, the kit cannot repair that damage.
Use VW-spec ATF G 055 025 or an equivalent that meets that specification. The level is set at the check plug with the engine running and the fluid at the specified temperature, not with a dipstick.
Yes. The computer learned around the worn valve body, so clear the adaptations with a scan tool and drive the car through a full range of shifts so it relearns clutch fill times. Expect shifts to settle over the first several drives.
Test them while the valve body is out. Linear solenoids that stick at operating temperature cause the same hot harsh downshifts and flares as worn valves, so replace any that test slow or out of spec.
