When you say "changing speed" do you mean changing gears?  It could be the 
switch mounted on the top of the transmission.  The one that detects when either 
third or fourth gear is selected.  First check to see if it is loose.  If it 
is not then try removing one of the shims used to adjust the height of the 
switch.

When you do this set the transmission in either third or fourth before 
screwing the switch in.  If the switch binds before it gets tight on the shims then 
it is too tight and you may need another switch.
