Hi everyone!

I have a 2013 Skoda Octavia III 1.6 TDI 105 PS (CLHA), with a 5-speed manual gearbox and around 250,000 km.

The engine was originally remapped from 105 to 155 PS, and the exhaust system has since been modified and emptied out. I estimate it might now produce around 170 PS, although this hasn’t been confirmed on a dyno.

Recently, I’ve started having problems selecting gears, especially when downshifting into 4th, 3rd and 2nd.

Sometimes it feels as if the gear lever hits a mechanical stop, and I have to apply more pressure than normal to engage the gear. Rev-matching or giving the throttle a quick blip sometimes helps.

I’ve also noticed that 5th gear can be difficult to engage, and the lever doesn’t always seem to return smoothly from the 5th gear position. However, the lever seems to return to the centre normally from the other positions.

The clutch doesn’t slip, and gear selection doesn’t seem to improve significantly with the clutch pedal fully depressed.

The problems appeared after someone else drove the car quite aggressively, including some hard acceleration and rough gear changes.

I’ve already adjusted the gear selector cables following an online tutorial, but unfortunately the problem persists.

I’m wondering whether this could be caused by worn gearbox components, damaged synchronisers, a clutch issue, or something else.

Has anyone experienced similar symptoms with this 5-speed gearbox?

I’m also planning to check the gearbox oil level.

Any advice or experiences would be greatly appreciated!

Thanks in advance!

Where is the biting point of the clutch?

The biting point is around halfway through the pedal travel, perhaps slightly lower, closer to the floor.

With the clutch pedal fully depressed and a gear engaged, the car doesn’t try to move at all.

The clutch doesn’t slip under load either. Even when driving uphill in a high gear, the engine revs drop rather than the clutch slipping.

With the engine switched off, all gears engage more easily, even without pressing the clutch pedal. However, I can still feel the mechanical engagement of each gear through the gear lever, almost as if I can feel the gears engaging.

With the engine running, shifting is noticeably harder, especially when downshifting.

I’ve already adjusted the gear linkage following a tutorial, but unfortunately it hasn’t solved the problem.

Personally, I would suspect the plastic components in the gear linkage, the gearbox oil level or condition, or even worn synchronisers before blaming the clutch.

Of course, I could be wrong, but the clutch itself seems to be working fine to me.

What do you think?
