09G Shift Kit, new and ready to install. Fits the 09G. Ships fast from the USA.
The usual 09G complaint goes like this: the car shifts fine on a cold morning, then after twenty minutes of driving it bangs into second or third as you slow down, flares on the 2-3 upshift, or the converter clutch slips at highway cruise. That pattern is typical of a worn valve body and tired linear solenoids, and that is exactly what the TransGo SK 09G repairs. It is a valve body repair kit for the six-speed Aisin unit VW calls the 09G (and 09M/09K), sold as the AW TF-60SN and used in Jetta, New Beetle, Passat, Audi A4 and TT and Mini Cooper models, so you can fix the hydraulics without buying a complete valve body.
In this transmission the computer controls each clutch through its own solenoid. TransGo's instructions separate them into two groups: N88 and N89 are on-off solenoids that read about 11-13 ohms, and the rest (N90, N91, N92, N93, N282 and N283) are pulse-width linear solenoids that read about 5-7 ohms. The linear solenoids send signal oil to the K1, K2, K3, B1 and TCC regulator valves, which set how hard each clutch applies. Over time the solenoid armatures drag in worn bushings and the signal circuits leak, so the regulators respond late and the clutch apply goes from crisp to sloppy. The SK 09G attacks both ends: it restores the large-body linear solenoids, opens specific signal-feed holes in the separator plate so the solenoids get a cleaner signal to their valves, and replaces the TCC regulator valve with a new valve and bushing. TransGo is clear that the drilled holes are not clutch feed holes, so this is a repair kit that restores factory-quality shifts, not a harsh racing calibration.
Read the transmission codes and look at the fluid first. Clean fluid with no heavy friction debris points toward the valve body; burnt fluid and a slipping clutch under load mean the unit needs a rebuild and a kit alone will not cure it. Our Aisin harsh or delayed shift walkthrough covers the checks in order. Because the first step in TransGo's procedure is a resistance test, you can check each solenoid with a meter before you commit; see how to test a transmission solenoid with a multimeter. A solenoid that is open, shorted or out of the 5-7 ohm range has to be replaced rather than repaired.
This is the TransGo SK 09G listed by TransGo for the 09G, 09M, 09K, AW TF-60SN and GAF21WA from 2003-2013, on valve bodies with a 1.100 in solenoid can outside diameter. The instruction sheet names applications including the 2003 VW Touran, 2005 Jetta 1.9-2.5L and New Beetle, 2006 Passat 2.0L and 3.6L, 2006 Audi A4 2.0L, 2003-04 Audi TT 1.8L, and the 2002 Mini Cooper and 2008 Clubman. Some valve bodies use small-body solenoids; the replacement end caps in this kit fit only the large-body style, so measure a solenoid can before you start. Confirm the transmission code on the case tag, or send us your year and VIN. Other parts for this Aisin family are on our Aisin transmission parts page.

TransGo lists this kit for 09G-family units from 2003 to 2013 with a 1.100 in solenoid can outside diameter. Later valve bodies changed, so check the transmission code on the case tag and measure a solenoid can, or send us your year and VIN before ordering.
Both are the TransGo SK 09G. The difference is the listing's year label; TransGo's own fitment covers 2003-2013 units with the large-body solenoids, so use whichever matches your order and confirm the solenoid can size either way.
No. TransGo's instructions state the enlarged separator plate holes are signal circuits between solenoids and valves, not clutch feed holes for firmer shifts. The goal is to restore normal, consistent shift quality on a worn valve body.
A digital ohmmeter, a micrometer or caliper to measure the solenoid shaft, a bench grinder for the end-cap crimp, a drill for the separator plate holes, brake cleaner, red threadlocker and a clean workspace. A scan tool is needed afterward to reset adaptations.
Install a new filter and pan gasket and refill with ATF that meets VW spec G 055 025. The 09G has no dipstick; the level is set at the check plug with the engine running and the fluid in the specified temperature range.
Usually not. Slipping in all gears with dark, burnt fluid points to worn clutches, and the unit needs a rebuild. The kit is for shift-quality and converter-slip complaints caused by valve body and solenoid wear.
