PCM / TCU / ECU Software Issue - Software issues can cause erratic shifting or downshifting issues.

This issue affects mainly newer VW models. Low Battery Voltage - In rare cases, the low battery voltage can trigger Volkswagen automatic transmission to get stuck in limp mode.If VW transmission shifts properly when you manually release the shifter from Park, the problem in most cases is the brake light switch or the shifter module itself. Manually override the shifter and move the gear selector to Drive.

The shifter can not be moved the transmission won't go into gear. Brake Light Switch - A faulty brake light switch can prevent the shifter from moving out or back in Park.A signal from the VSS is sent to the Powertrain Control Module (PCM), and the loss of the signal can cause one or more problems. Vehicle Speed Sensor - If your Volkswagen has developed a harsh shift between gears or is stuck in emergency mode (limp mode), the vehicle speed sensor (VSS) may be the problem.Depending on the competent that fails, it can cause limp mode, check engine light, the transmission may not shift past 2nd or 3rd gear or harsh shifting between gears. Mechatronic Unit / Valve Body - The valve body is complex and can fail in many ways the most common symptom is that your VW won't shift or go in gear.Shifter- A faulty shifter or shifter cable can cause the transmission to get stuck or not go in the selected gear.A more common issue on high mileage VW vehicles.

Worn Bands - Can cause delayed shifting, shifting at high RPM, harsh shifting, VW won't move, and no reverse gear.

Faulty Torque Converter - Can cause VW transmission to slip in all gears, shuddering, and overheating.

Low transmission fluid level - Low transmission fluid level can cause many issues, including erratic shifting, no shifting at all, delayed shifting, strange grinding noises, limp mode, and in some cases, check engine light comes on.

The transmission range sensor can fail, causing many issues such as the vehicle going in limp mode, transmission not shifting when placed in Drive or Reverse, and the engine may not start because the PCM can not detect the shift Park. The transmission range sensor then sends the signal to the Powertrain Control Module (PCM).

Transmission Range Sensor (F125) Volkswagen transmission range sensor serves many functions to determine the gear the driver has selected ( P R N D ).

Possible CausesĬommon problems that affect Volkswagen transmissions:

These symptoms can also indicate a serious problem: faulty valve body, clogged transmission filter, bad solenoids, bad VW mechatronic unit, and faulty torque converter. Volkswagen transmission problems such as erratic shifting, limp mode, no shifting, no reverse can be due to something as simple as low transmission fluid level.

Noise such as whining, humming, or clunking.

Here are some of the most common problems with Volkswagen transmissions: You will learn about transmission problems such as faulty transmission range sensor, reset Volkswagen transmission adaptive settings, check transmission fluid level, and retrieve transmission diagnostic trouble codes from the Transmission Control Module (TCM). Don't panic if your Volkswagen transmission is no longer shifting, shifts hard, or is stuck in gear.
