Rough shifting / hard gear engagement
Hard to select gears or notchy shifts; can be clutch, linkage, fluid, or synchros.
MEDIUM RISK
Common symptoms
- Hard into 1st/reverse
- Grinding on shifts
- Worse when cold
Cost expectations
Typical costs vary by car and region. Use this as a ballpark.
- DIY / parts: £20–£80
- Garage / labour: £80–£250
Most likely causes (ranked)
Start at the top. Rule out the common, cheap causes before expensive ones.
- Clutch not fully disengaging — Hydraulics/bleeding; causes gear crunch.
- Low/old gearbox oil — Cold notchiness improves when warm.
- Worn linkage/bushes — Sloppy or hard engagement.
- Synchro wear — Specific gear grind; requires rebuild.
- Dual-mass flywheel issues — Vibration + engagement issues.
Quick checks (fast, low-cost)
Fast checks you can do with basic tools before buying parts.
- Check clutch pedal feel and bite point.
- Try selecting gear with engine off vs on (difference suggests clutch drag).
- Inspect for clutch fluid leaks / low reservoir.
- Check linkage for play; adjust if applicable.
- Change gearbox oil with correct spec if due.

What to do next
- Fix clutch drag first before blaming gearbox.
- If only one gear grinds consistently, suspect synchro.
