Transwin 01M927321B Automatic Transmission Speed Sensor for VW 01M 01N AG4
Product Description / Overview:
Restore flawless shift timing and eliminate speed signal dropouts with the premium Transwin Automatic Transmission Speed Sensor (OEM Number: 01M927321B / 01M 927 321 B). Specially engineered for the iconic Volkswagen (VW) Group 01M and 01N series 4-speed automatic gearboxes, this high-precision electromagnetic pickup sensor monitors internal gear rotational speeds to feed the Transmission Control Module (TCM). Manufactured to strict global aftermarket benchmarks, it effectively resolves common drivetrain diagnostic issues, including harsh limp-mode activation, cruise control failure, erratic speedometer readings, and gear hunting.

⚠️ Rebuilder Technical Hint:
When diagnosing an 01M transmission that suddenly drops into 3rd-gear limp mode with a 'No Speed Signal' diagnostic fault code (G68/G38 sensors), always check the wire harness leading to this 01M927321B sensor for cracks. Because these sensors sit externally on the casing, their wiring harnesses are highly prone to road debris impact and engine heat degradation.
