Grinding noises typically indicate worn-out gears or bearings, while whining can suggest gearbox or clutch assembly issues. Addressing these early can prevent further damage.

This may result from hydraulic problems, clutch actuator failures, or gearbox sensor issues. Common symptoms include lack of acceleration or dashboard "Gearbox Fault" messages.

Overheating can cause sluggish shifts, reduced power, or "limp mode." It's often due to low fluid levels, clogged filters, or cooling system problems.

Unresponsive paddle shifters may stem from faulty wiring, sensor issues, or mechanical failure, preventing manual gear changes.

This often results from clutch drag, where the clutch isn’t fully disengaging due to hydraulic issues or a faulty clutch master/slave cylinder.

Diagnostics include scanning for error codes, inspecting fluid levels, and examining the clutch actuators, TCM, and internal gearbox components.
