325i gearbox...

[sunnyr83]

Anyone know the syptoms of a warn out gearbox? When the car is in idle there is a knocking/rattling sound but when i press the clucth halfway down it goes... Think i have read on here that its a gearbox problem..is it a replace only or something smaller job. Thanks..

That'll be wear in the layshaft. Its a common symptom on E30's. It could well go on like this for ages.

Make that.."could go on like that for years" , mine certainly did before it blew a rear seal and stuffed it properly.

Oh bugger....sounds exactly like my 325 cabby engine.Will a nice refill of new gearbox oil help?

Thanks for the replies guys....

I had it on my old 4 pot and that was for 3 years but i didnt know what it was so left it. Whats the solution then? Want to sort it out as its annoying me now.

The solution is a know good gearbox to fit onto the car

Has anyone bothered getting their noisy input shaft bearing replaced?

Is it worth doing, if you can source a known-to-be quiet secondhand 'box?? I'm sure I read somewhere that E30 Getrag 'boxes have been known to be noisy from new.

I got quoted £500 to rebuild a 325 cr sport box. . .

Once my 'box runs-up the white flag, I'll be replacing it with a c/r 'box. But what I'll probably do is;-
1) Make sure I can test it before I buy it
2) If there's any doubt about the input shaft bearing, get my local transmission specialist to replace it for me.

I can reassure you it's a worthwhile upgrade
