Workarounds Described

leaves car for 20 minutes then continues driving
mechanic checks but can't reproduce issue

Implied Software Gaps

Logging tool that captures transmission data over weeks to capture intermittent faults

App Concept

GearShift Diagnostic Recorder

A plug-in OBD-II device that continuously monitors transmission parameters (clutch actuation, shifter position, gear engagement force) and logs anomalies for later analysis. Stores 30 days of driving data, accessible via mobile app, to help mechanics pinpoint intermittent gear-shifting faults.

Key Features

Continuous 24/7 transmission data logging
Automated anomaly detection for gear engagement resistance
Mobile app with downloadable logs and diagnostic summary
Integration with common OBD-II protocols

Target Users: DIY car owners and independent mechanics who need to diagnose intermittent manual transmission issues

Revenue Model: $99 one-time device purchase plus $5/month cloud storage subscription
