Replaces the worn shift and pressure control solenoids in the Aisin TF60-SN (VW 09G) six-speed behind 2.0L and 2.5L Jetta, Golf and Passat.
A 2.5L Jetta, Rabbit, Golf or Beetle, or a 2.0L Passat, that shifts fine cold and then starts slamming the 3-2 or flaring the 2-3 once it is hot is the classic picture of a tired 09G solenoid. This kit is built for that job on the Aisin TF-60SN six-speed that Volkswagen codes 09G. As pictured, the box holds six slim-body solenoids together with a pan filter and a molded pan gasket, so the pan comes off once and goes back on with fresh sealing parts.
The 09G does not use a conventional clutch switch valve. Every clutch and brake has its own linear solenoid that sets how fast that element fills and exhausts: N92 for K1, N282 for K2, N90 for K3 and N283 for B1, all fed by a solenoid modulator valve. Every shift is an overlap between two or three of these, timed by the TCM against load, rpm and temperature. Sonnax points out that N90 and N282 work hardest in city traffic, which is why one or both tends to hang up first and produce rough coastdown shifts. The remaining solenoids handle line pressure and converter clutch control.
Scan the TCM first and note which solenoid or clutch the faults point to. A hot-only complaint is a strong hint: debris lets the plunger seize in the coil bushings at operating temperature, so a solenoid can ohm out fine on a cold bench and still be the problem. Shops confirm it with a hot soak test, warming the solenoid and checking that the plunger rattles freely. Our bench testing guide for transmission solenoids covers resistance and function checks. If the fluid is black and burnt, clutch damage has likely started and solenoids alone will not fix it.
Listed fitment: VW Jetta 2.5L 2005-2010, Rabbit 2.5L 2006-2009, Passat 2.0L 2006-2010, Beetle 2.5L 2008-2017, Golf 2.5L 2010-2014 and CC 2.0L 2009. Be aware that VW changed solenoid size and filter design during 2008, and these year ranges straddle that change. The solenoids in this kit are the slim style; if you pull the pan and find fat 1.0 inch cans on your valve body, our large-can 09G eight-solenoid kit is the one to order. Compare your original solenoids and filter side by side with the photos, or send us your year and VIN and we will check before it ships.
If new solenoids do not cure a hot flare, the solenoid modulator or clutch control bores are worn and a 09G valve body with solenoids is the next step.

As pictured, six slim-body solenoids plus a transmission filter and a molded pan gasket. It does not include fluid; add a service kit or ATF meeting VW G 055 025.
VW changed solenoid size and filter design during 2008, so model year alone does not settle it. Compare your original solenoids to the photos, or send us your year and VIN. Large 1.0 inch cans need our eight-solenoid large-can kit instead.
Debris can make a linear solenoid plunger seize in its coil bushings at operating temperature. The result is good shifts cold and a harsh 3-2 or flared 2-3 hot. That is the most common reason to replace the solenoid set.
No programming, but reset the transmission adaptations with a scan tool and drive through all six gears so the TCM relearns clutch fill times against the new solenoids.
Only if new solenoids do not fix it or the scan data points to bore wear. Worn solenoid modulator or clutch control bores cause flares and harsh shifts that solenoids cannot cure, and then a valve body is the right repair.
