Disco 2 manual gearbox

Hi everyone.
Due to drive from Cornwall to Yorkshire on the 28th.
After problems with my oil pressure light the other day now been fixed, another problem has appeared.
I went to go into 2nd gear around a roundabout and it wouldn't go in so tried 3rd that wouldn't either. So rolled to side of road and pulled up. After restarting engine I managed to get in gear and drive home. Sometimes the gear changes were good, sometimes they crunched and sometimes I couldn't hit any gear at all. I've also heard a slight metallic knocking coming from underneath occasionally in 2nd and 3rd generally when under pressure. 3rd gear gets the knocking most accompanied by a whirring kind of noise.
Any one have any ideas as to what's causing it.
My garage is closed until new year now. Looks like the trip to Yorkshire will have to wait as this is my daily driver.
All help much appreciated.

I was going to suggest that the bias plate might have broke, but maybe not after reading your bit about the whirring noise.

OK thanks for replying I'm clueless myself, can't say I know much about gearboxes.

Have a shufty at this thread.

Not saying that this is the issue, but it's an easy enough to check. If it's not the bias plate, then it may be a tad more serious.

Thanks for that. I will take a look tomorrow and pray that this is the problem as I'm sure it will be the best problem I could ask for relating to this.
Fingers crossed. I'll post back tomorrow and let you know. Cheers for the help.

Post back with any findings as there are a lot more knowledgeable peeps on here than me, but they've probably all retired to bed by now.

I will do. Haha I would have retired to bed by now too but instead I'm up reading about my landrover problems . Oh I do love landrover's.

Just remembered also when I got into 3rd sometimes not all the time it was like there was juddering after I had accelerated for a while. So maybe its not the bias plate and I may be looking to remortgage shortly. Or could this still be a cause from the bias plate?
I will check it out tomorrow anyway. But this went away when I changed up into 4th or 5th.

Not sure anymore... maybe it is an actual gearbox issue rather than the bits attached to it..... Hopefully some of the more experienced members might offer up some of their wisdom gems when they fall out of bed

bias plate only makes selection more difficult,as gear stick isnt located properly at 3rd 4th position,theres lots of reasons for noise ie prop ujs but if its only in certain gears theres a box issue

Thanks James

OK thanks guys, obviously not what I was hoping for but it is what it is I guess. Looks like the trip to Yorkshire is cancelled until I can get her in the garage.

Just to update you all it was the gearbox been advised best to fit another gearbox.

Terminal then ??

Unfortunately so. Just sourced a 2nd hand gearbox what has to be delivered from Wales.
