Question
Hi Roger,
  I actually have several question for you.

1.  How would I go about changing the transmission fluid,
   I cannot seem to find the drain plug for the
   transmission and could you give me a step by step
   instruction.  
2.  I have a squeaky glove compartment and it drives me
   insane to listen to it make noise while I drive how
   would I eliminate the noise.  Step by Step instruction
   here, please.  
3.  The moon roof also makes noise when I go over unsmooth
   sections of the freeway.  How would I get it to stop?
   Step by Step instruction
   here, please.  
4.  I am interested in installing a methanol/alcohol
   injection system in my car.  What are the necessary
   products and up grades I need to purchase inorder to
   make this happen?  Can you please provide me with step
   by step instructions here also, please.

Thank you very, much Roger!

Daniel,  Number 1.  You need a transmission pan gasket kit and filter.  There is no drain plug on this one.  I dont do step by steps, sorry.  2.  No idea without looking at it.  3.  what kind of noise?  4.  I have no idea, never heard of anyone wanting to spend that kind of money on an S80.  Roger
