I was driving home from work in my 110TDi yesterday afternoon, and came to do a multi vehicle overtake. I dropped from 5th to 4th, and pulled out. Went past two cars and a lorry, and then I came to change to 5th, but it the gear lever refused to moved properly - just felt like there was something rubbery blocking it. I tried a couple of times, and then released my foot from the clutch, depressed it again and then I was able to enage 5th.

However by this point I had lost some speed, i dropped in infront of the lorry I had just overtaken, rather than completing the overtake (one final lorry).

I have noticed this problem once or twice before (and am sure I have posted about it). The problem always seem to occur at speed (and the worst possible moment) - ie. when performing an overtake - the other time that springs to mind was on a dual carriageway, so a drop of speed was not so much of an issue (but still a pain in the backside till I could engage 5th).

Any ideas?

Done the usual checks on gear alignment, console bush and dogbone bushes?

not as yet..... was interested as why it only seems to happen at speed as well....

Engine physically shifting at high speed/load?

You've done over 100k now, so it might be worth getting a couple of new wires for the gear change and putting a bit of suitable grease on the gear leaver ball joint.

Have you done a gear oil change in the last 50k?

Also worth checking the dogbone and other mounts out too, but if you do don't forget to put new bolts to the correct torque in.
