I have a brand new and unused clutch delay valve that I no longer need. It is the same as pictured here in red.

If you modify this valve and replace your old one with this, it makes a big improvement to the smoothness of gear changes, especially first and second.

This is a BMW part, is made in Germany, and has the part number 21 52 6 755 892.

£12 including P+P

Here is how to modify the valve:

I'm not sure Chris, definitely for 2.5i, 3.0i and 3.0si as per here: http://www.zeckhausen.com/CDV.htm

It makes it a lot smoother, especially from 1st to 2nd! BMW boxes are quite clunky anyway but the resrictor/piston makes it much worse. At £12 it's seriously good value for money! Of course you need to modify it first as above...
