- 6. LESSON: COMMON TROUBLES OF MANUAL TRANSMISSION
- 7. INTRODUCTION Manual transmission issues can develop because of high mileage, abuse, or lack of proper maintenance, however, they’re rather rare.
- 8. INTRODUCTION Most manual transmission problems originate not with the transmission itself, but from connected parts like the clutch assembly, linkage, or driveline: the parts that transmit turning power from the transmission to the wheels.
