Why does a manual transmission have a severe drag feeling when releasing the throttle?
2 Answers
Manual transmission has a severe drag feeling when releasing the throttle because the moment the throttle is released triggers the automatic transmission to upshift. After upshifting, the gear ratio decreases, causing the engine to lose RPM. Additionally, the throttle release instantly increases the RPM, so the reduced engine RPM after upshifting leads to decreased torque. With less power, the engine can no longer pull the moving vehicle effectively and instead gets dragged by the vehicle. A manual transmission, also known as a manual gearbox, is a type of gearbox and one of the most basic types in automotive transmissions. Its function is to change the gear ratio, also known as the gear ratio, which utilizes the principle of leverage to amplify engine torque using larger diameter gears in lower gears with longer radii, helping the vehicle start moving forward.
Manual transmission exhibits noticeable engine braking drag, which can stem from multiple causes. When the clutch is worn, engagement becomes less smooth, leading to jerky power delivery. Excessive play in worn CV joints causes driveshaft wobble upon throttle lift-off, resulting in abrupt 'nose-dives'. Additionally, cracked chassis rubber bushings lose damping effectiveness – particularly when rear suspension control arm bushings fail, creating pronounced rear-end squat. Many owners misdiagnose this as transmission issues, only to solve it by replacing engine mounts. Prioritize checking these components' clearances; regular bushing replacement is crucial for older vehicles to prevent entire-body clunking. If the symptom worsens after hard acceleration, also inspect spark plugs and intake systems.
