01M Solenoid Kit 1995-2006, remanufactured and ready to install. Fits the 01M. Ships fast from the USA.
If your Jetta, Golf, GTI, New Beetle or Cabrio automatic leaves every stop in third gear, refuses fourth, or slams into Drive, the seven solenoids on the 01M valve body are one of the first places to look. This is a remanufactured set covering the full 1995-2006 run of the 01M, so the same kit serves an early Mk3 Jetta and a late Mk4 Golf or New Beetle. Replacing all seven together makes sense on a transmission this age: when one coil has failed, the others have the same miles and heat cycles on them.
The 01M is a fully electronic four-speed. There is no governor or throttle valve cable; the transmission control module reads vehicle speed, engine load and throttle position and switches solenoids on the valve body to apply each clutch and brake. VW labels the seven positions N88 through N94. Six of them are shift and lockup solenoids that should read 55-65 ohms according to a Transmission Digest case study, and one, N93, is the electronic pressure control solenoid that should read only about 4.5-6.5 ohms. N93 sets line pressure, and N91 handles converter clutch lockup. The module watches every circuit, and if one reads open, shorted or out of range it falls back to its emergency program: third gear only, with no upshifts or downshifts. That is why a single weak solenoid can make the whole transmission feel broken.
Do the electrical work before buying anything. In the Transmission Digest case behind our sources, a 1998 Jetta with an 01M had already had two solenoids and the internal harness replaced on codes alone, and the codes came straight back. The real story took two steps to find: an aftermarket radio was loading the K-line so the scan tool could not talk to the module properly, and one solenoid read 4.7 ohms when it should have been near 60. Check battery voltage and the scan connection, then measure each solenoid from the module connector. Our guide on testing a transmission solenoid with a multimeter walks through the readings, and solenoid testing without a factory scan tool helps if you only have a basic reader. If the solenoids measure good at the valve body but bad at the module plug, the fault is wiring, and a new 01M internal wiring harness is the part you actually need.
The listing covers the 01M from 1995 through 2006. That family includes the Mk3 Golf, GTI, Jetta and Cabrio automatics, the Mk4 Golf, GTI and Jetta, and the New Beetle; transverse Passats of 1995-1997 also used it. Mk3 cars built before the 01M used the 096 four-speed, which looks similar from underneath, so read the code letters on the case rather than assuming by model. Lay your old solenoids next to the photo and match connector shapes, or send us your year and VIN and we will check it for you. Other 01M hard parts are on our hard parts page, including a lower-cost 1995-05 01M solenoid kit if you want to compare options.
Drain the fluid, drop the pan and strainer, unplug the internal harness and lower the valve body. Move one solenoid at a time so each goes back into its own bore, lube the new O-rings with clean ATF and make sure every retaining plate seats flat. Inspect the solenoid bores while you are there: worn bores in the aluminum valve body are a known 01M failure, and if a new solenoid sits loose, a 1999-2005 01M valve body is the better fix. Look hard at the pan and magnet too; heavy friction material means the clutches are going and an 01M overhaul kit belongs on the bench instead. Refill with ATF that meets VW G 052 162 A2 and set the level at the check plug with the fluid at VW's specified temperature, since the 01M has no dipstick. Finish by clearing codes and resetting adaptations, as covered in our adaptive relearn guide.

It is listed for the 01M from 1995 through 2006, which covers Mk3 and Mk4 Golf, GTI and Jetta automatics, the New Beetle and the Cabrio. Early Mk3 cars with the older 096 transmission are different, so check the case code letters or send us your VIN.
Seven, one for each of the N88 through N94 positions on the 01M valve body, including the N93 line-pressure solenoid and the N91 converter lockup solenoid.
The shift and lockup solenoids read about 55-65 ohms and the N93 pressure control solenoid about 4.5-6.5 ohms, measured from the module connector. A reading far below spec, like 4.7 ohms on a shift solenoid, means a shorted coil.
Not always. Third gear is the 01M fail-safe mode and it can be triggered by a cracked internal harness, corroded terminals, low voltage or a bad solenoid. Test the circuits first so you replace the right part.
Use ATF meeting VW G 052 162 A2. The 01M has no dipstick; fill through the fill plug and set the level at the check plug with the fluid at VW's specified temperature.
Clear the stored codes and reset the shift adaptations with a VW-capable scan tool, then drive the car through all four gears so the module relearns shift timing.
