More gear selection issues - advice please?

GregorJP · 11-04-2012, 01:24 PM

So my car has decided that on the odd occasion, it doesn't like 4th gear when changing up very much and instead of selecting the gear, I get a horrible grinding sound and no gear (much the same as if driving a manual and selecting a gear without fully engaging the clutch). When it has happened, I've taken my foot off the gas, waited a second, selected 5th and it's fine. I can then select 4th again no problem.

Until the weekend, this had happened only 3 times in 5,000 miles and each time it happened on the track, under load and after a fair bit of track time. I assumed it was God's way of telling me to show more mechanical sympathy.

However, at the weekend, it happened just pootling down the road.

I've recently had a new clutch and flywheel, so I can only imagine it's a selector issue, but any ideas would be gratefully received. Cheers.

Murketts had mine in over a year ago now, I believe dear old Andy was still alive even so maybe longer, checked box, and said there was nothing wrong ...we need Gareth to give a view !

You need a new gearbox !

I changed everything on mine (2nd hand gearbox , acuator , pump) and it still had the same symptoms .
Then i bought a gearbox of a friends M3 (wich i knew was working perfect ) and now everything is fine .

I have booked whats left of my car into Elms for next Monday, but will probably trailer it over there sometime this week, probably Friday now, anyone else booked in ?

Ah, video brings back the exact god-awful sound I heard at the weekend. It's exactly the same as in Duncan's clip. Think I'll live with it as long as I can - it's only happened on very odd occasions so far...but I'll keep the group updated as it sounds like a common issue and I daresay a new gearbox will happen sooner or later.
