oops did it again

["David Templeton" <davidt@opentext.com>]

Afternoon all,

 

While out at lunch in the spitfire changed gears from 4th down to 3rd and
got a "crunch".  The last time this happened, the circlip that holds the
2nd/3rd gear cluster broke and fell down in the bottom of the gearbox.  The
gearbox is less than 7500km on this clip and it is GT6 MKIII with OD.  

 

Questions:

 

-          Is this normal given normal driving conditions?  

-          Is this a weak point of this gearbox?

-          Can I fix this easily?  Simply take out this and that in units
and put back is the reverse 

-          Instructions anyone????

 

Thanks in advance
