Seven-piece shift, TCC and EPC solenoid set for the VW 01M 4-speed automatic in 1995-2005 Jetta, Golf, Beetle and Passat with harsh or stuck shifts.
The four-speed automatic in a Mk3 or Mk4 Jetta, Golf, GTI or New Beetle has a reputation, and a lot of it comes down to seven small solenoids. When a 1995-2005 Volkswagen with the 01M starts slamming into second, sticks in third with the shift lever doing nothing, or locks the converter with a shudder, this direct-replacement set lets you renew every solenoid on the valve body at once instead of guessing which one is next.
The 01M (also called the 097) has no throttle cable or vacuum modulator; the transmission control module does all the thinking and the solenoids do the work. VW numbers them N88 through N94. The on/off valves switch oil to the shift valves to select each gear and to apply and release the torque converter clutch. One solenoid, the electronic pressure control unit, is different: it has a much lower coil resistance and is driven with a varying current to set main pressure and shift feel. If that one weakens, every shift goes firm or soft at once; if a shift valve solenoid sticks, you lose one particular gear change. When the module sees an electrical fault it falls back to a fixed third gear so the car can still be driven, which is the classic 01M limp mode.
Pull faults with a scan tool that reads the VW transmission module. A solenoid fault means check the wiring first: the ribbon harness inside the pan and the case connector are common culprits, and a cracked or chafed 01M internal wiring harness sets the same codes as a dead solenoid. With the connector off, measure each circuit; the shift solenoids should read far higher than the pressure control solenoid, and one that is open or shorted is easy to spot. Our guide to solenoid testing without a factory scan tool walks through it, and testing with a multimeter covers the meter side. Also check for aftermarket electronics on the diagnostic line, which have caused false transmission faults on these cars.
This set is for the 01M (097) in 1995-2005 Jetta, Golf, GTI, Cabrio and New Beetle automatics, and the transverse-engine 1995-1997 Passat. It crosses to 095 927 331 and 095 927 333 D plus the aftermarket numbers 119952, 119954, 119957A, 75421A, 75431A and 75446K. The 1998-2005 Passat with the longitudinal engine is not an 01M; it uses the five-speed 01V, which takes a 5HP19 solenoid kit instead. The listing also names the related 096 (01N) and 098 (01P); those units vary, so compare connector color and body shape to your originals, or send us your year and VIN. More parts for this unit are under transmission hard parts.
Drain the fluid, remove the pan and strainer, and unplug the ribbon harness. Remove the valve body, then the retaining clips, and pull the solenoids one position at a time so each new one lands in the right bore with the matching connector color. Soak the O-rings in fresh ATF, seat each solenoid fully and refit its clip. While the valve body is out, look at the bores for scoring, a common 01M wear point; a badly worn body is better replaced with an 01M valve body. Refit with a new filter and gasket from the 01M service kit, fill with VW-specification ATF and set the level at the specified fluid temperature with the engine running. Clear faults and run the adaptation reset; adaptive relearn after a valve body job explains what the module needs to relearn.

Probably not. Passats built 1998-2005 with the longitudinal engine use the five-speed 01V. This set is for the 01M four-speed found in the Jetta, Golf, GTI, New Beetle, Cabrio and 1995-1997 Passat.
All seven have the same miles and heat on them. Replacing the whole bank costs little more than one valve body removal and keeps you from doing the job twice.
No. It is a direct-replacement aftermarket set that crosses to the VW part numbers listed on this page.
No. Third-gear limp mode is the module protecting itself after any electrical fault, including the internal harness, case connector or a speed sensor. Read the faults first.
Refill with VW-spec ATF, check level at the specified temperature, clear the faults and reset the adaptations so shift pressures are relearned.
