Nissan Repair: 1996 Sentra manual transmission, clutch fluid, drain bolt

Question
I just bought a 96 Sentra five speed with 79K miles on it for my son and have been doing some maintenance on it.  I can't find anything in the manual for maintenance on the manual transmission.  Is there some gear oil fluid to change?  I haven't looked underneath for it, is there a drain bolt for it?  

Also, is the clutch pedal travel adjustment easy to make?  Where would I adjust that?  Seems like the free play at the beginning of the travel is too long.  

Thanks!

Clay,

Forgive me for taking so long to answer.  The server has been down for a couple of days.  The answer on the transmission is that you could change the fluid and use the recommended fluid from the owners manual.  I think it is Dextron II.  On the clutch there is no adjustment and the thing to do is change the clutch fluid to Ford High Performance Brake Fluid.  Currently, it has DOT3 and that is fine.  But, if you like a better pedal feel go with the fluid I recommend as it does not compress as much.
