The shifter feels fine, great actually. I don't recall the numbers, but I used the recommended redline oils for a manual trans. Also, my valve ticking seems to have quieted today with the warmer oat. I think I am going to replace the oil again with the standard BMW stuff and watch them this time.

I forgot to post this a few days ago... Normally when the you have a bad gear or transmission... you will get gear noise only at part throttle. IF you apply power it will go away. Because the gear's bearings are under load. When there is little power - like cruising - that is when you will hear a noisey (worn out) trans.
Also... gear noise from the diff... is different in that it is speed dependent. You will also only hear it while cruising at a steady speed. Apply some power and the noise will generally go away. Until the internal wear becomes so great it will just make noise ALL the time.
IF you suspect your trans is screwed up. The best thing would be to drain the trans fluid and inspect the old fluid for metallic bits. Feel it with your fingers for any grit. You could also send a sample out for analisis.
The best way to make sure your trans has the proper fluid level is to change it and keep filling the fill hole until fluid spills out of the fill hole. NOTE: your car must be on level ground too!
